Description

The present invention relates to a water-based composition that can be used as a raw material for a polymerized / cured product, a curable material, etc. in various industrial applications, a method for polymerizing / curing the composition, and a polymerized / cured product.

Water-based compositions such as water-based resin compositions and water-based curable compositions include organic solvent-based compositions such as organic solvent-based resin compositions and curable compositions in which VOC (volatile organic compound) emission is a problem. In contrast, it is useful as a technology with low environmental impact.
By the way, an anion is a substance having a negative charge, and is present in an electrolyte solution or an ionic substance (so-called salt), and there are various inorganic and organic anions. Among them, the polymerizable unsaturated carboxylate anion which is an organic anion can be polymerized in an electrolyte solution such as an aqueous solution, and is often polymerized and cured in the form of an aqueous solution of a salt with a metal cation or an organic cation. The polymerized / cured product is mainly applied in water-based applications. As such a polymerizable unsaturated carboxylate anion, anions of (meth) acrylic acid, maleic acid, and itaconic acid are known, and in particular, the anion of (meth) acrylic acid is a highly polymerizable anion. It is also important industrially.

Among these, as an aqueous composition using a salt comprising an anion of (meth) acrylic acid and various cations, an aqueous polymerizable monomer composition obtained by neutralizing a carboxyl group of (meth) acrylic acid with a polyvalent metal ion An aqueous polymerizable monomer composition in which 10 to 90% of the carboxyl group is neutralized is disclosed (for example, Patent Document 1).
As described above, this aqueous composition is a composition that requires unneutralized (meth) acrylic acid, a polyvalent metal salt of (meth) acrylic acid, and water, and is not neutralized. It is characterized by containing a certain amount of (meth) acrylic acid. In other words, by making (meth) acrylic acid play a role as a reactive diluent, it is possible to impart film-forming properties to a polyvalent metal salt of (meth) acrylic acid, which is not film-forming by itself, It is characterized in that the curability of the resin can be improved. A gas barrier film can be produced by applying this aqueous composition on a base film and curing it in a wet state, or by sandwiching and curing between the base film and the base film, but has a low environmental impact. This is a useful technique because it is an aqueous composition and can employ a high productivity process utilizing ultraviolet curing.

On the other hand, as the polymerizable unsaturated carboxylic acid compound, like (meth) acrylic acid ester, α-allyloxymethyl as a polymerizable compound having a double bond activated by conjugation with an adjacent carbonyl group is used. Compounds in which an allyloxymethyl group is introduced at the α-position of an acrylate ester, such as ethyl acrylate and α-allyloxymethyl acrylate, are disclosed (for example, see Non-Patent Document 1 and Non-Patent Document 2). It is disclosed that this compound undergoes cyclopolymerization by a radical addition polymerization mechanism to produce a soluble polymer.

Robert D. Thompson, two others, “Macromolecules”, 1992, 25, p. 6455-6459 Michio Urushizaki, 4 others, “Macromolecules”, 1999, vol. 32, p. 322-327

However, water-based compositions tend to be limited in the types of functions that can be exhibited compared to organic solvent-based compositions, and have poor performance levels.
In addition, with regard to the conventional salt composed of a polymerizable unsaturated carboxylate anion, many of them are powdery or crystalline solids at room temperature and have poor film-forming properties. It was necessary to use some kind of reactive diluent like the reactive monomer composition. Therefore, the reactive diluent is required to be capable of providing a film-forming property by dissolving a high concentration of carboxylic acid metal salt, and to be soluble in water. Sexual diluents are very limited. Moreover, although it is also necessary to be highly polymerizable, polymerizable unsaturated carboxylic acids other than (meth) acrylic acid are not sufficiently polymerizable. Therefore, the practically useful reactive diluent is about (meth) acrylic acid, but (meth) acrylic acid does not have a sufficiently high boiling point. Therefore, when an aqueous curable composition containing (meth) acrylic acid is applied and dried, (Meth) acrylic acid is volatile. As a result, the carboxylic acid metal salt may precipitate and the coating film may be whitened, and careful attention is required to control the content of (meth) acrylic acid in the composition and the coating / drying conditions. In addition, a small amount of volatilized (meth) acrylic acid may cause damage to equipment or personnel health in the work environment.

On the other hand, regarding the polymerizable unsaturated carboxylic acid compound, the compound in which an allyloxymethyl group is introduced at the α-position of an acrylate ester such as ethyl α-allyloxymethylacrylate and methyl α-allyloxymethylacrylate is described above. In the prior art documents, addition polymerization properties based on a radical or anion mechanism are disclosed, but nothing is described about α-allyloxymethyl acrylate anion and salts thereof. In addition, there is no mention of what kind of problem a compound having an allyloxymethyl group introduced at the α-position of an acrylate ester has as a polymerizable compound.

The present invention has been made in view of the above problems, and includes a diene carboxylate anion or a salt thereof, which has not been studied so far, and has excellent film forming properties and polymerizability, and is environmentally friendly. An object is to provide an aqueous composition having a low load. Further, it provides a polymerization / curing method for the aqueous composition, and further provides a polymerized / cured product obtained by the polymerization / curing method, that is, water resistance, curability, hardness, scratch resistance, and fingerprint resistance. Properties, gas barrier properties, water vapor barrier properties, oxygen absorption properties, UV cut, infrared cut, color development / coloring, high refractive index, adhesion, various catalytic functions, fluorescence / light emission, light amplification, dispersibility, antistatic, Another object of the present invention is to provide a polymerized / cured product having excellent characteristics that are expressed by introducing ionic bonds, particularly ionic bonds via metal ions, into the polymerized / cured product.

The present inventor conducted various studies focusing on 1,6-diene-2-carboxylic acid compounds, and the anion of 1,6-diene-2-carboxylic acid and its salt are novel substances. It has different characteristics from polymerizable unsaturated carboxylate anions and their salts, and unsaturated carboxylate compounds that have an allyloxymethyl group at the α-position of an acrylate ester. I found that I can do it. That is, the diene carboxylate anion and its salt are found to have extremely excellent polymerizability and excellent film forming properties, and an aqueous composition containing the diene carboxylate anion or a salt thereof. Has been found to have excellent film-forming properties and polymerizability, and has been conceived to solve the above-mentioned problems.

Furthermore, the polymerized / cured product has water resistance, curability, hardness, scratch resistance, fingerprint resistance, gas barrier property, water vapor barrier property, oxygen absorption property, ultraviolet ray cut, infrared ray cut, coloring / coloring, high refractive index. Adhesiveness, various catalytic ability, fluorescence / luminous ability, light amplification, dispersibility, antistatic, and other excellent properties expressed by introducing ionic bonds and metal ions into the polymerized / cured product Because it has coating material, ionomer resin, adhesive, sealing material, adhesive, paint, pigment dispersion, reactive emulsifier, reactive surfactant, metal / metal oxide fine particle dispersion, ink, resist, MOD material , Molding material, gas barrier material, water vapor barrier material, oxygen absorbing material, lens, dental material, antibacterial agent, rubber, tire, lighting, solar cell, wiring material, electrode material, plating undercoat, optical fiber From optical waveguides, superconducting materials, semiconductor chips, magnetic materials, memories, capacitors, piezoelectrics, etc., I thought that it can be widely applied in various fields such as information technology (IT) field, automobile, architecture, medical care, daily necessities, The present invention has been achieved.

The present invention is described in detail below.
In this specification, “(meth) acrylic acid” represents acrylic acid or methacrylic acid. “(Meth) allyloxymethylacrylic acid” represents allyloxymethylacrylic acid or methallyloxymethylacrylic acid.

Regarding the constitution of the present invention, first, regarding the diene carboxylate anion and its salt, which are essential components of the aqueous composition of the present invention, (1) basic chemical structure of the diene carboxylate anion and its salt, (2 ) The performance derived from the diene carboxylate anion moiety, the preferred diene carboxylate anion structure, (3) The performance derived from the counter cation moiety, and the preferred counter cation structure, (4) Diene Specific examples of the carboxylic acid salt, (5) diene carboxylic acid anion and a method for producing the salt will be described. Next, the aqueous composition, the polymerization / curing method thereof, and the polymerization / cured product thereof will be described.

<Diene carboxylate anion and its salt>
(1) The basic chemical structure of the diene carboxylate anion and its salt will be described.
As shown in the general formula (1), the diene carboxylate anion in the present invention has a structure that is a monovalent anion in the whole bond of oxygen atom-carbon atom-oxygen atom. As in the case of the carboxylate anion, in the case of a highly polar solvent such as water, the solvent is solvated and ionized (so-called electrolyte solution), in a low polarity solvent or a poor solvent, or substantially In the absence of a solvent, it exists in the state of an ionic substance (so-called salt) bound to a counter cation by an ionic bond. In the present specification, “substantially solvent-free” means a form that does not contain a solvent and a form that contains a solvent but contains a trace amount so that the solvent effect is not exhibited. Yes.

In order to confirm that the diene carboxylate anion in the present invention exists in the “anion” state, it can be confirmed by the same method as that applied to the identification of a normal carboxylate anion. This will be described in detail below.
Carboxylate anion (COO) ^-, as shown by the following general formula (3), an oxygen atom - the carbon atom - two carbon atoms contained in the binding of the oxygen atoms - oxygen bonds are equivalent, the binding It is generally known that the strength is intermediate between a C═O double bond and a C—O single bond, and the entire bond of oxygen atom-carbon atom-oxygen atom is a monovalent anion (for example, , Identification method by spectrum of organic compound (4th edition) / Tokyo Chemical Dojin, p117).

On the other hand, as shown in the following general formula (4), in the carboxylic acid or carboxylic acid ester, the two carbon atom-oxygen atom bonds contained in the bond of oxygen atom-carbon atom-oxygen atom are not equivalent.

In the formula, R represents a hydrogen atom or a hydrocarbon group.

Such a difference in bond equivalence and bonding force appears prominently in the infrared spectrum, and carboxylic acids and carboxylic acid esters have a strong absorption band derived from C═O stretching vibration in the vicinity of 1700 to 1750 cm ⁻¹ and 1200 cm. while causing absorption band derived from C-O stretching vibration in the vicinity of ^-1, the carboxylate anion, the region between the C = O stretching vibration and C-O stretching vibration (COO) ^- antisymmetric and symmetric Absorption bands derived from stretching vibrations are generated. In general, the anti-symmetric stretching absorption band near 1600 cm ^-1, symmetric stretching absorption band near 1400 cm ^-1 is evidence that a carboxylate anion structure (e.g., the identification method according to the spectrum of the organic compound (a 4th edition) / Tokyo Chemical Doujin, p118).

The diene carboxylate anion in the present invention is similar to a normal carboxylate anion, although it varies to some extent depending on the sample concentration, the type of solvent, and the type of counter cation coexisting in the electrolyte solution or ionic substance. , in the infrared spectrum, resulting opposite symmetric stretching absorption band near 1600 cm ^-1, the symmetric stretching absorption band near 1400 cm ^-1. That is, the reverse symmetric stretch absorption band of the diene carboxylate anion is generated in a region having a frequency lower than the C═O stretch vibration of the corresponding diene carboxylic acid or diene carboxylate ester, and is usually 1500 to 1650 cm ^−1. Observed between. In addition, the symmetric stretch absorption band of the diene carboxylate anion is generated in a region having a higher frequency than the C—O stretch vibration of the corresponding diene carboxylic acid or diene carboxylate, and is usually 1300 to 1500 cm ⁻¹ . Observed between. Note that in the infrared spectrum of a sample containing a diene carboxylate anion, the C═O stretching vibration of the carboxylic acid may disappear almost completely, or significant intensity absorption may be observed. Depending on the synthesis conditions, the raw material carboxylic acid added excessively may remain, and the remaining protic neutral low molecular weight compounds such as water and alcohol and the diene carboxylic acid anion. This is because proton exchange may occur, and depending on the analysis conditions, absorption due to the strong C═O stretching vibration of carboxylic acid may be observed.

The unique phenomenon that can be attributed to the carboxylate anion structure can also be observed in the ¹³ C-NMR spectrum. For example, in general, the absorption of the central carbon atom of the carboxylate anion is often shifted to the lower magnetic field side than the absorption of the carbonyl carbon atom of the corresponding carboxylic acid or carboxylate ester. The same phenomenon is often observed in the diene carboxylate anion in the present invention.

Further, the diene carboxylate anion, due to the presence of the double bond of the hydrogen atom H _a and H _b in the vicinity of the carboxylate anion structure as shown in following general formula (5), ^{1 H-NMR} absorption of these H _a and H _b in the spectrum becomes a good indicator for confirming that you have a carboxylate anion structure. Specifically, in comparison with the double bond hydrogen atom of the corresponding diene carboxylic acid or carboxylic acid ester, a phenomenon in which the chemical shift values of H _a and H _b shift to a higher magnetic field side is often observed. .

The absolute value of the chemical shift value and the shift width of the characteristic absorption in the NMR spectrum vary depending on the sample concentration, the type of solvent, the type of counter cation coexisting in the electrolyte solution or ionic substance, and the like. In addition, depending on the type of counter cation, the peak may be broadened due to the formation of a polymeric stable complex, the influence of paramagnetism, etc., and fine assignment may be difficult. For example, it is considered that the peak is broadened when oxygen in the air, which is a paramagnetic substance, is easily combined with a counter cation to form a stable radical, or when the counter cation itself is a paramagnetic substance. Such peak broadening is often seen when the counter cation contains a transition metal.

The diene carboxylate anion in the present invention can be analyzed by various chromatographic techniques. For example, if an electrolyte solution containing a diene carboxylate anion or a salt containing a diene carboxylate anion is pretreated with a strong acid to obtain a diene carboxylate, it can be analyzed by gas chromatography or liquid chromatography. Examples of such strong acids include sulfuric acid, hydrochloric acid, nitric acid, organic sulfonic acid, phosphoric acid, and the like, and may be appropriately selected depending on the sample and the apparatus. In liquid chromatography, the same effect can be obtained by mixing a strong acid with the elution solvent. If ion chromatography or capillary electrophoresis is used, it can be directly analyzed as ions.

The diene carboxylate according to the present invention is an ionic substance in which an equivalent anion and a counter cation are ion-bonded to be electrically neutral as a whole (electrically neutralized), A diene carboxylate in which at least one of the anions is a diene carboxylate anion.

The diene carboxylate according to the present invention may have the same chemical formula depending on the structure and type of counter cation, solvent, sample concentration, temperature, etc. Even if the ratio of the ion to the counter cation is the same), the coordination structure may take a plurality of different structures. In addition, these different coordination structures can be easily and reversibly converted to each other, and as a result, it is not uncommon for them to be a mixture of multiple coordination structures. These multiple coordination structures are isolated or identified.・ It is not easy to quantify.
Such a phenomenon may occur when the counter cation can take a plurality of coordination numbers, and is particularly likely to occur when the counter cation is a metal atom or an atomic group composed of a metal atom. Taking a salt represented by chemical formula (RCOO) ₂ M (RCOO: carboxylate anion, M: metal cation) as an example, a plurality of coordination structures can be taken as shown in FIG. In addition, what was shown in FIG. 1 is a one part example, and does not show all the coordination structure examples.
In this way, the counter cation can take multiple coordination numbers, and the carboxylate anion can also take multiple coordination ways, so even with salts of the same chemical formula, they can take different coordination structures. Can do.

In general, the carboxylate anion is often monodentate (ligidentate), bidentate (brident), bridging, etc. It is known (for example, Non-Patent Document 3, Non-Patent Document 4, Non-Patent Document 5 below).
Non-Patent Document 3: BASIC INORGANIC CHEMISTRY (SECOND EDITION) / John Wiley & Sons, p143
Non-Patent Document 4: Principles and Applications of Organotransition Metal Chemistry / UNIVERSITY SCIENCE BOOKS, p59
Non-Patent Document 5: ADVANCED INORGANIC CHEMISTRY (FIFTH EDITION) / John Wiley & Sons, p483

As described above, there are many examples of anions other than carboxylate anions in which the actual coordination structure does not match the chemical formula. For example, titanium tetraalkoxide composed of alkoxide ions (RO ⁻ ) and titanium, usually expressed as Ti (OR) ₄ , is known to be a polymer having a tetramer structure as shown in FIG. (For example, BASIC INORGANIC CHEMISTRY (SECOND EDITION) / John Wiley & Sons, p142).
Therefore, the diene carboxylate in the present invention is not a concept indicating a single coordination structure, but is a salt represented by the same chemical formula (that is, the ratio of diene carboxylate anion to counter cation is A concept that includes a plurality of different coordination structures. In other words, if the chemical formulas are the same, it is a concept that treats different coordination structures (either a single coordination structure or a mixture of multiple coordination structures) as the same. .

In the diene carboxylate according to the present invention, at least one valence of the counter cation may be occupied by the diene carboxylate anion according to the present invention, and the remaining valence is diene carboxylate anion. It may be occupied by anions (anionic ligands) other than ions. In addition to the diene carboxylate anion and other anions, a neutral molecule (neutral molecular ligand) that can donate an electron may be coordinated to the counter cation. Examples of such anions (anionic ligands) include oxide ions (O ²⁻ ), halogen ions, hydroxide ions, alkoxide ions, and carboxylate anions other than diene carboxylate anions. Acetylacetonate ion, carbonate ion, bicarbonate ion, nitrate ion, nitrite ion, sulfate ion, sulfite ion, hydrogen sulfite ion, phosphate ion, silicate ion, borate ion and the like. Examples of the neutral molecular ligand include water, alcohols, ammonia, amines, phosphines, β-ketoesters, cyclopentadiene, and the like. In addition, a large number of anions (anionic ligands) and neutral molecular ligands are known. For example, inorganic chemistry and organic metals listed as Non-Patent Documents 3 to 5 above It is mentioned everywhere in chemistry books. The diene carboxylate according to the present invention contains only one kind of such an anionic ligand or neutral molecular ligand depending on the valence of the counter cation and the possible coordination number. You can also have multiple types of different types.

From the above, the diene carboxylate in the present invention is represented by a chemical formula comprising at least a chemical formula representing a diene carboxylate anion and a chemical formula representing a counter cation. In some cases, it is represented by a chemical formula including a chemical formula representing an anion (anionic ligand) other than the diene carboxylate anion and a neutral molecular ligand. The ratio of these diene carboxylate anions, counter cations, anions other than diene carboxylate anions (anionic ligands), and neutral molecular ligands is expressed by the smallest integer ratio. It is. If the diene carboxylate anion is RCOO, the anion other than the diene carboxylate anion (anionic ligand) is X, the neutral molecular ligand is L, and the counter cation is M. In the present invention, the diene carboxylic acid is “(RCOO) _a (X) _b (L) _c (M) _d ” (a, b, c, d is the minimum integer ratio, and a, d is 1 or more. And b and c are integers of 0 or more). However, for the neutral molecular ligand L, it may be difficult to distinguish whether it is a salt with L or a mixture of L and a salt as impurities.

(2) Performances derived from the diene carboxylate anion moiety and matters relating to a preferred diene carboxylate anion structure will be described.
The diene carboxylate anion in the present invention has extremely excellent polymerization and curability, and is solvated and ionized with a solvent molecule such as in a highly polar solvent such as water (so-called electrolyte solution). In an ionic substance (so-called salt state) bound to a counter cation by an ionic bond, such as in a low-polar solvent or a poor solvent, or substantially in the absence of a solvent.
This is because the diene carboxylate anion can be cyclopolymerized by the mechanism shown in FIG. 3, and the α-position of the double bond conjugated with the carbonyl group is sterically crowded. Nevertheless, it is considered to exhibit high polymerization / curability.

Among these, from the viewpoint of polymerization activity, it is preferable that X ¹ and Z ¹ are the same or different and a methylene group or a methylene group in which a hydrogen atom is substituted with a methyl group, Y ¹ = oxygen atom, and X ¹ = More preferably, Z ¹ = methylene group, Y ¹ = oxygen atom, that is, the diene carboxylate anion is an anion of α- (meth) allyloxymethylacrylic acid.

The diene carboxylates in the present invention exhibit excellent solubility and compatibility with various general-purpose organic solvents, reactive diluents, and resins from low polarity to high polarity, and in some cases Becomes liquid at room temperature. This is because the diene carboxylate anion contains many organic groups and an ether structure.

When the diene carboxylate anion in the present invention is such that Z ¹ in the general formula (1) is a methylene group, that is, when a (meth) allyl group is included in the structure, it is so-called in the presence of active oxygen. Polymerization and curing based on an oxygen curing (also referred to as oxidation polymerization) mechanism is possible. As a typical compound that polymerizes and cures based on the oxygen curing mechanism, there is a polyfunctional alkyl allyl ether compound. The curing mechanism is shown in FIG. 4 (FIG. 4 is a simplified conceptual diagram). The actual oxygen curing mechanism is quite complex). When Z ¹ in the general formula (1) is a methylene group, it can be polymerized and cured by the same mechanism as shown in FIG.
Therefore, it is preferable that X ¹ is a methylene group or a methylene group in which a hydrogen atom is substituted with a methyl group, Z ¹ is a methylene group, Y ¹ = oxygen atom, and X ¹ = Z ¹ = methylene group. , Y ¹ = oxygen atom, that is, the diene carboxylate anion is more preferably an anion of α- (meth) allyloxymethylacrylic acid.

(3) A description will be given of the performance that is derived from the counter cation moiety and the preferable counter cation structure.
The counter cation affects the solubility of the diene carboxylate, the film forming property, curability, and the properties of the cured product. What is necessary is just to select suitably according to the objective and a use.

The counter cation can be classified into a cation that is a metal element (metal atom) or an atomic group containing a metal atom, and a cation that is an atomic group composed of a non-metal atom. Examples of the former cation include sodium ion and potassium ion. Examples of the latter include alkali ions such as quaternized ions of group 15 elements (ammonium ions, phosphonium ions, etc.), and ions obtained by cationizing typical nonmetallic elements such as onium ions (also referred to as onium ions). It is done.

When the counter cation is an atomic group containing a metal atom and an atomic group containing both a metal atom and a non-metal atom, the entire atomic group containing a metal atom and a non-metal atom is conventionally used as 1 In some cases (for example, [ZrO] ²⁺ , [(C ₂ H ₅ O) Al] ²⁺ , [(n-C ₄ H ₉ ) ₂ Sn-O-Sn (n-C ₄ H ₉ ) ₂ ] ²⁺ ) etc.). In this case, from the viewpoint of the difference in electronegativity, there is a way of thinking that an atomic group consisting of only a metal atom or a metal atom is a cation and the other part is an anion ([ZrO] ²⁺ is Zr ⁴⁺ and O ²⁻ , [(C ₂ H ₅ O) Al] ²⁺ are Al ³⁺ and C ₂ H ₅ O ⁻ , [(n—C ₄ H ₉ ) ₂ Sn—O—Sn (n—C ₄ H ₉ ) _2] ^{2+ Sn 4+} 2 pieces and ^{O 2-} and _n-C 4 _{H 9} ^- 2 pieces). The diene carboxylate according to the present invention contains the diene carboxylate anion according to the present invention as an essential anion. If the salt is electrically neutral as a whole, the counter cation is a metal atom. And the whole atomic group containing non-metallic atoms may be regarded as one cation, or the atomic group consisting only of metal atoms or metal atoms strictly is a cation, and the other part is regarded as an anion. Also good.

In particular, when the counter cation is a cation which is a metal atom or an atomic group containing a metal atom, the polymer / cured product of a composition containing a diene carboxylate has not only a characteristic derived from ionic bonds but also a metal itself. Since the derived characteristics can be imparted, the utility value is very high. That is, the diene carboxylate in the present invention is a diene carboxylate whose counter cation is a cation that is a metal atom or an atomic group containing a metal atom (hereinafter also simply referred to as a diene carboxylate metal salt). More preferred).

The metal atom (metal element) is a typical metal element or a transition metal element. Typical metals are usually alkali metals (metals consisting of elements other than hydrogen in the periodic table group 1), alkaline earth metals (metals consisting of elements of the periodic table group 2), metals consisting of elements of the periodic table group 12 A metal consisting of an element other than boron in the periodic table group 13, a metal consisting of an element excluding carbon and silicon in the group 14 of the periodic table, a metal consisting of an element excluding nitrogen, phosphorus and arsenic in the group 15 of the periodic table, In Table 16, it refers to a metal composed of elements other than oxygen, sulfur, selenium, and tellurium, but in the present invention, it may be classified as a semimetal such as boron, silicon, arsenic, selenium, or tellurium. Elements can also be included as metal atoms. A transition metal refers to a metal composed of elements of Groups 3 to 11 of the periodic table.

Hereinafter, the diene carboxylic acid according to the present invention will be described in detail mainly with respect to the case where the counter cation is a metal atom or a cation that is an atomic group containing a metal atom (hereinafter sometimes simply referred to as a metal ion). The counter cation of the salt is not limited to the following examples, and does not exclude a cation (hereinafter sometimes referred to as an organic cation) which is an atomic group composed of nonmetallic atoms.

When a diene carboxylate containing a metal ion as a counter cation is polymerized / cured and a metal is introduced into the polymerized / cured product, so-called hard coat properties such as surface hardness and scratch resistance may be improved. At the same time, passive barrier properties (oxygen barrier properties, water vapor barrier properties, etc.) may be improved. Furthermore, when Z ¹ in the general formula (1) of the diene carboxylate anion is a methylene group, that is, when the diene carboxylate anion contains a (meth) allyl group in the structure, Thus, it is possible to exhibit barrier properties by an active mechanism (a mechanism that chemically absorbs oxygen). Therefore, it can be suitably used for hard coat materials, sealants, protective films, molding materials, gas barrier materials, water vapor barrier materials, and the like. Such an effect is often manifested when a metal ion has a high valence and a high-density crosslinked structure is formed by metal-mediated ionic bonds.

Therefore, the metal contained in the counter cation is preferably a metal capable of taking a valence of 2 or more, such as an alkaline earth metal, a typical metal of Groups 12 to 16 of the periodic table, and a transition metal of Groups 3 to 11 of the periodic table. . Considering the availability of metals and the ease of synthesis, magnesium, calcium, strontium, barium, scandium, yttrium, lanthanoids, titanium, zirconium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese , Iron, ruthenium, cobalt, rhodium, iridium, nickel, palladium, platinum, copper, silver, gold, zinc, aluminum, gallium, indium, silicon, germanium, tin, lead, antimony, bismuth and the like.
Since transition metal elements such as chromium, manganese, iron, and cobalt are often colored, if you do not want to color as much as possible, magnesium, calcium, strontium, barium, zinc, aluminum, gallium, indium, germanium, tin, lead, Typical metals such as antimony and bismuth, group 3 transition metals such as yttrium and lanthanum, and group 4 transition metals such as titanium and zirconium can be particularly preferably used.

When a diene carboxylate containing a metal ion as a counter cation is polymerized / cured and a metal is introduced into the polymerized / cured product, the refractive index may be increased by introducing the metal into the polymerized / cured product. Yes, it can be preferably used for optical materials such as lenses, optical films and optical fibers. In addition, when used as an optical material, it is often advantageous that the coloring is light or colorless. From this viewpoint, the metals contained in the counter cation include magnesium, calcium, strontium, barium, zinc, and aluminum. Typical metals such as gallium, indium, germanium, tin, lead, antimony and bismuth, group 3 metals such as yttrium and lanthanum, and group 4 transition metals such as titanium and zirconium can be particularly preferably used.

When a diene carboxylate containing a metal ion as a counter cation is polymerized / cured and a metal is introduced into the polymerized / cured product, electromagnetic waves in a specific wavelength range may be absorbed depending on the type of the metal. That is, since it can be utilized as a light-cutting agent or a polymerizable colorant for coloring, it can be used for ultraviolet-cutting, infrared-cutting, X-ray blocking, coloring filters, and the like. For example, in the case of a colorless to light color light filter, magnesium, calcium, strontium, barium, zinc, aluminum, gallium, indium, germanium, tin, lead, antimony, bismuth and other typical metals, yttrium, lanthanum and the like 3 Group 4 transition metals such as Group, Titanium, and Zirconium are particularly preferably used.

On the other hand, when used as a coloring filter (coloring agent), transition metals belonging to Group 5-11 such as vanadium, chromium, manganese, iron, cobalt, nickel, copper, etc. can be preferably used. Furthermore, particularly when used as a colorant, by combining a plurality of metal species or an organic cation such as an ammonium salt or a phosphonium salt, light absorption characteristics that cannot be produced with a single metal ion may be exhibited. Is possible. As such a combination of cations, any combination of cations is possible, but a combination including a transition metal is particularly preferable. For example, by combining copper and lanthanum, light absorption characteristics exhibiting a bright blue color that cannot be obtained with copper alone can be developed. Moreover, in order to change the light absorption characteristics, not only the adjustment of the counter cation moiety but also the combination of anions other than the diene carboxylate anion in the present invention, or the combination of neutral ligands such as amines and phosphines. It is also effective to do.

When a diene carboxylate containing a metal ion containing a rare earth metal element as a counter cation is polymerized / cured, and the rare earth element is introduced into the polymerized / cured product, it may be able to impart fluorescence / light emission capability, It can be applied to display devices, solar cells, optical fibers, etc. For example, when europium is introduced, red fluorescence can be developed, and when erbium is introduced, application to an optical fiber utilizing light amplification is possible. Similarly to the case of using as a colorant, fluorescence and luminescence can be obtained by combining a plurality of kinds of cations, anions other than the diene carboxylate anion in the present invention, or neutral ligands such as amines and phosphines. It is also possible to adjust the characteristics. The rare earth element refers to 17 elements including lanthanides from lanthanum to lutetium and scandium and yttrium.

When a diene carboxylate containing a metal ion as a counter cation is polymerized / cured and a metal is introduced into the polymerized / cured product, the polymerized / cured product may exhibit catalytic ability depending on the introduced metal. That is, it can be used as a solid catalyst. Since the diene carboxylic acid metal salt in the present invention is easily soluble in many organic solvents, reactive diluents and resins, it can be easily processed into various forms, for example, film-like, thin-film-like, particulate-like, It is possible to obtain a solid catalyst in a preferable form suitable for the method of use. The metal may be selected according to the intended reaction, but considering the types of reactions that can be handled, typical metals of Groups 12-16 of the periodic table and transition metals of Groups 3-11 of the periodic table are preferred. Specifically, for example, titanium, zirconium, zinc, aluminum, tin, lead and bismuth are catalysts for various organic reactions such as urethanization catalysts and transesterification catalysts, and vanadium, chromium, manganese, cobalt, cerium and the like are oxidized. It can be preferably used as a catalyst. Moreover, what polymerized and hardened the diene-type carboxylate in this invention which consists of a cation containing ammonium salt and phosphonium salt as a counter cation can also be used as a catalyst.

When diene carboxylates containing metal ions as counter cations are polymerized and cured, and when metal is introduced into the polymerized / cured product, antibacterial, bactericidal, antifungal and antibiotic adhesion can be imparted Therefore, it can be applied to antibacterial coating, sterilization coating, anti-mold coating, ship bottom coating and the like. As such a metal, zinc, copper, silver and the like are particularly preferable. In addition, a polymer obtained by polymerizing and curing the diene carboxylate according to the present invention, which includes a cation containing an onium ion such as an ammonium salt or a phosphonium salt as a counter cation, may exhibit the same effect.

A polymer obtained by polymerizing and curing a diene carboxylate may be capable of imparting antistatic ability. Examples of such counter cations include organic cations such as metal ions having high affinity with water such as magnesium, calcium, and barium, and quaternized ions of group 15 elements such as ammonium ions and phosphonium ions. .

A polymer obtained by polymerizing and curing a diene carboxylate can be applied as an adhesive or a primer because it exhibits good adhesion to both an inorganic material and a resin material. The type of counter cation may be a metal ion or an organic cation, and may be appropriately selected according to the type of adherend.

The shape of the adherend may be a block shape or a plate shape, and may be selected according to the purpose and application.
As a suitable plate-shaped adherend, inorganic substrates include: glass substrate; ceramic substrate; inorganic substrate such as calcium silicate plate, asbestos slate plate, cement slate plate; aluminum plate, copper plate, stainless steel plate, Although metal base materials, such as a plated steel plate, are mentioned, this invention is not limited only to this illustration.

Examples of suitable plate-shaped adherends include resin-based (meth) acrylic resins such as polymethyl methacrylate; polystyrene, polyvinyltoluene, polystyrene, styrene-methyl methacrylate copolymer, styrene-acrylonitrile. Copolymer, acrylonitrile-butadiene-styrene block copolymer, styrene resin such as poly (p-methylstyrene); polycarbonate; polyarylate; polyethersulfone; polyolefin resin such as polyethylene, polypropylene, ethylene-propylene; norbornene Cyclic olefin resins such as resins; halogen-containing resins such as vinyl chloride resins and chlorinated vinyl resins; polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polycyclohexane dimeta Polyester resins such as nylon terephthalate; polyamides such as nylon 6, nylon 66 and nylon 610; cellulose resins such as cellulose triacetate, cellulose acetate propionate and cellulose acetate butyrate; polyacetal resins; polyvinyl fluoride, polyfluoride Fluorine resins such as vinylidene, polychlorotrifluoroethylene, polyethylenetetrafluoroethylene, polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, tetrafluoroethylene-hexafluoropropylene copolymer; polyphenylene oxide; polyphenylene sulfide Polyetheretherketone, polyethernitrile, polysulfone, polyethersulfone, polyoxybenzile ; Polyamide-imide; silicone resin, resin base material and the like, the present invention is not limited only to those exemplified. Among these resins, (meth) acrylic resins, polyolefin-based resins, cyclic olefin-based resins, polyester-based resins, polyamides are versatile and adherent to those obtained by polymerizing and curing diene carboxylates. Cellulose resins and fluororesins are preferred, and (meth) acrylic resins, cyclic olefin resins, polyester resins, and cellulose resins are more preferred.

Although the thickness of the resin base material is not particularly limited, it is usually preferably about 10 to 800 μm.
In addition to the above-mentioned base materials, woody base materials such as plywood, MDF (medium density fiberboard), and particle board can also be used.

The diene carboxylate can be used as an undercoat agent when the resin is metal-plated. Usually, the types of resins that can be easily metal-plated are limited, and complicated pretreatments such as the treatment of unevenness on the surface of the resin to improve plating adhesion, treatment with a plating activator or a plating catalyst, etc. Although necessary, if a diene carboxylate is used as an undercoat agent, a part or most of the complicated pretreatment may be omitted. Such a counter cation may be a metal ion or an organic cation, and may be appropriately selected according to the type of resin or plating. A counter cation containing a transition metal is preferable, and in particular, noble metals such as silver, gold, and platinum are used. When it is included, it is possible to form metal nanoparticles at the same time as being cured by UV irradiation, and to perform electroless plating using the generated metal nanoparticles as a nucleus, or in some cases, electrolytic plating. When combined with microfabrication technology using photocuring such as photolithography and UV nanoimprint technology, fine conductive wiring and black matrix can be formed on a resin film without high-temperature heat treatment.

In addition, it is generally known that metal fine particles having a carboxylic acid moiety on the surface can be obtained from a carboxylic acid metal salt as a raw material by hydrolysis, oxidation treatment, reduction treatment, energy ray irradiation, etc. In the same manner, diene carboxylic acid metal salts containing metal ions can be made into fine particles. That is, polymerizable metal fine particles having a diene carboxylic acid moiety on the surface of the metal fine particles can also be obtained.

Diene carboxylates containing metal ions as counter cations are useful as raw materials for composites containing metal nanoparticles or metal oxide nanoparticles. In particular, when a metal (such as silver or gold) that has the property of being reduced from an ion to a metal by UV irradiation is included, the metal nanoparticles are generated at a very high concentration by being cured by UV irradiation and simultaneously generating metal nanoparticles. Thus, a uniformly dispersed composite can be easily prepared. If the particle diameter is controlled to be about several nm to 100 nm, a material having plasmon absorption peculiar to metal nanoparticles can be obtained, and it can be applied to a color material, a sensor or the like using plasmon absorption. Depending on the diameter and concentration of the metal particles, it can also be used as a conductive material. In addition, when combined with microfabrication technology using photocuring such as photolithography and UV nanoimprint technology, it is also useful as a raw material for producing fine wiring and metamaterials.

The diene carboxylate according to the present invention containing a metal ion as a counter cation can be used as a radical curable MOD (Metal Organic Decomposition) material. A conventional MOD material is a film-forming composition comprising a non-polymerizable organic solvent-soluble long-chain carboxylic acid metal salt or an organic solvent-soluble metal alkoxide, which is applied to a substrate and dried. The obtained coating film is a metal or metal oxide film (hereinafter sometimes simply referred to as a metal thin film) decomposed at high temperature, and then fired at high temperature to be densified and crystallized metal. It is a material for obtaining a thin film. However, in order to obtain a finely processed metal thin film using a conventional MOD material, the metal thin film is etched using a positive resist after the metal thin film is formed, or a high output energy beam such as an electron beam is dried. A complicated process such as irradiating the coating film to fire and crystallize only the irradiated part and an expensive apparatus are required. Since the diene carboxylic acid metal salt in the present invention has high radical curability, inexpensive energy rays such as a plate making process (photolithography) using a photomask and UV light, ultraviolet curable nanoimprint, visible light laser and infrared laser, etc. A simpler plate-making process such as direct drawing by thermosetting or thermosetting nanoimprinting can be employed.

Although a preferable metal changes according to the composition of the target metal thin film, a preferable metal species is particularly preferable for a semiconductor chip, a superconducting material, a magnetic material, a memory, a capacitor, and a piezoelectric body. Specifically, strontium, barium, scandium, yttrium, lanthanoid, titanium, zirconium, hafnium, niobium, thallium, chromium, molybdenum, manganese, iron, cobalt, nickel, copper, silver, zinc, aluminum, gallium, indium, silicon , Germanium, tin, lead, arsenic, antimony, bismuth, selenium, tellurium and the like. Also, diene carboxylate and conventional non-polymerizable metal salt can be mixed with diene carboxylate and conventional non-polymerizable metal salt. Even in the form of complex chlorination, both high radical curability and film forming properties can be achieved, and it can be suitably used as a MOD material.

In the diene carboxylic acid metal salt, when an alkali metal or alkaline earth metal is used as a metal, it is possible to obtain a polymer that is soluble or swells in an organic solvent or water, and such a polymer is dispersed. It can be used for agents, water-absorbing resins, materials for ion secondary batteries such as lithium ion batteries, and the like. Further, as will be described later, diene carboxylic acid alkali metal salts, especially sodium salts and potassium salts are also useful as intermediate raw materials for producing metal salts other than sodium salts and potassium salts.

As described above, the diene carboxylate in the present invention will exhibit various different properties depending on the type of counter cation to be combined, and is preferable as a metal atom or non-metal atom serving as a counter cation or an atomic group composed of these. Things will depend on the application of the diene carboxylate. Further, by combining an anion other than the diene carboxylic acid in the present invention, various performances can be adjusted according to the application while retaining the characteristics of the diene carboxylic acid in the present invention.
The diene carboxylate anion in the present invention can be combined with various metal atoms, nonmetal atoms, or atomic groups comprising these, and diene carboxylates that can be suitably used for various applications. It has a great technical significance in that it is an anion that can be formed.

(5) A method for producing a diene carboxylate anion and a salt thereof will be described.
Examples of the method for producing a diene carboxylate anion and a salt thereof in the present invention include (i) a method of reacting a diene carboxylic acid or an anhydride of a diene carboxylic acid with a basic substance or a latent basic substance, ii) A diene carboxylate or diene carboxylate nitrile is hydrolyzed with a basic substance or a latent basic substance to form a diene carboxylate, and then exchanged with another cation as required. There are two major methods.

Method (i) is a type of neutralization reaction and is also referred to as a direct method. In some cases, method (ii) means two steps. In particular, the process of exchanging the cation at the second step for another cation is sometimes referred to as a metathesis method. If these methods are performed in an electrolyte solution, an ionized diene carboxylate anion can be obtained. Moreover, after performing these methods in a non-electrolyte solution, or performing it in an electrolyte solution, it can also be set as the state of a diene carboxylate by performing operations, such as solvent removal, solvent exchange, and extraction.
The basic substance or latent basic substance is a substance capable of generating hydroxide ions by reacting with water (which may be heated), and various organic bases such as ammonia and amines, And a simple metal, a metal oxide, a metal hydroxide, a metal alkoxide, and the like (hereinafter sometimes simply referred to as a base).
Therefore, in order to obtain a diene carboxylate anion, any one of a diene carboxylate, an anhydride of a diene carboxylate, a diene carboxylate, and a diene carboxylate nitrile is used as a raw material.

However, it is industrially disadvantageous to obtain the diene acyl group structure shown in FIG. 5 by a method other than the method of converting the α-position of acrylate ester or acrylonitrile. That is, as shown in FIG. 6, industrially, first, acrylic acid ester or acrylonitrile is used as a raw material, and then converted to diene carboxylic acid ester or diene carboxylic nitrile, followed by hydrolysis with a base to diene carboxylic acid. Diene carboxylic acid is obtained by hydrolysis with a salt or acid. When a salt of another cation is used, a direct method or a metathesis method is used. The hydrolysis of the diene carboxylic acid ester or the diene carboxylic acid nitrile is more preferably hydrolyzed with a base from the viewpoint that side reactions hardly occur and corrosion of the reaction apparatus hardly occurs. When a trace amount of alkali metal is not desired to be mixed, it may be preferable to hydrolyze with an acid using a corrosion-resistant reactor.
That is, a method for producing a diene carboxylate anion and a salt thereof, wherein 1,6-diene-2-carboxylic acid ester or nitrile is hydrolyzed with a basic substance or a latent basic substance, or with an acid. The method for producing a diene carboxylate anion and a salt thereof including a hydrolysis step is one of the preferred embodiments of the method for producing a diene carboxylate anion and a salt thereof.

In the following, the industrially advantageous production method of the diene carboxylate anion and its salt in the present invention will be described in detail. As a representative example of the diene carboxylate anion and its salt, α-allyloxymethylacrylic acid An anion (AMA ion) and its salt (AMA salt) are taken up. First, a method for producing AMA ions and AMA salts of α-allyloxymethyl acrylate ester (AMA ester) or α-allyloxymethyl acrylate nitrile (AMA nitrile) by hydrolysis with a base will be described in detail. . Next, a metathesis method for converting an AMA salt obtained by hydrolysis with a base into a salt of another cation will be described in detail. Furthermore, although the AMA salt obtained by hydrolysis with a base is converted into α-allyloxymethylacrylic acid (AMA carboxylic acid), a method for producing a salt of another cation by a direct method is described in detail. The method for producing a diene carboxylate anion and a salt thereof in the present invention is not limited to these.

First, a method for producing AMA ions and AMA salts by hydrolysis of AMA ester or AMA nitrile with a base will be described.
In this method, the reaction is allowed to proceed by stirring a basic substance or a latent basic substance with an AMA ester or AMA nitrile, preferably in the presence of water.
From the viewpoint of safety to living bodies, AMA ester is more preferable as a raw material.
As the AMA ester, a lower ester is preferable because of easy hydrolysis, and an ester having 1 to 5 carbon atoms such as methyl, ethyl, propyl, butyl, glycidyl, and tetrahydrofurfuryl is particularly preferable.

As the basic substance or the latent basic substance, an alkali metal or alkaline earth metal hydroxide is preferable in view of availability and reactivity. Most AMA esters are separated from alkali metal / alkaline earth metal hydroxides or their aqueous solutions, so they are suspended at the beginning of the reaction, but emulsify as the reaction progresses, and finally they are uniformly transparent. In many cases, it becomes liquid and it is easy to confirm the progress of the reaction.
As alkali metals and alkaline earth metals, lithium hydroxide, sodium hydroxide, potassium hydroxide, magnesium hydroxide, calcium hydroxide, strontium hydroxide, hydroxide are available in terms of availability and ease of reaction. Barium is preferable, and sodium hydroxide and potassium hydroxide are particularly preferable.
When these alkali metal / alkaline earth metal hydroxides are used as an aqueous solution, the concentration may be appropriately selected according to the type of AMA ester, reaction temperature, etc., but preferably 0.1 to 60% by mass. 1 to 50% is more preferable, and 3 to 40% by mass is most preferable.
The reaction temperature may be appropriately selected depending on the alkali hydroxide concentration and the type of AMA ester, but is preferably -20 to 120 ° C, more preferably -10 to 100 ° C, and 0 to 80 ° C. Most preferred.

Next, a method for producing by the double decomposition method will be described.
This method includes the AMA salt comprising the cation _M ^{a +} (expressed as _{"M a} salt of AMA"), and a raw material salt composed of a cation _M ^{b +} (simply referred to as "raw material _{M b} salt"), both In some cases, the cation is exchanged by mixing in the presence of a catalyst in the presence of a catalyst to produce an AMA salt composed of the cation M _b ⁺ (expressed as “AMA M _b salt”).
The solvent is as long as it can dissolve any part of both the M _a salt and the raw material M _b salt of AMA, water, preferably an alcohol, water is most preferred.
The M _a salt of AMA, alkali metal, or alkaline earth metal salts are preferred, availability, in terms of progression easiness of the reaction, in particular sodium salts, potassium salts are preferred.

Material M _b alkali metal or alkaline earth metal other than the metal salts as salts or ammonium salts, although phosphonium salts are preferred, when using sodium or potassium as M _a, M _b sodium or alkali metal or non-potassium as Alkaline earth metals can also be used. As the raw material _Mb salt, salts with various acids soluble in a solvent can be used, and a water-soluble salt is particularly preferable. Such a salt may be appropriately selected according to the target metal, but sulfate, nitrate, hydrochloride, sulfonate, phosphate, perchlorate, hydrobromide, carbonate, Examples thereof include acetates, and sulfates, nitrates, and hydrochlorides (metal chlorides) are particularly preferable from the standpoints of availability, water solubility, stability, and ease of metal exchange.
The reaction temperature may be appropriately selected according to the type of each cation (M _a ⁺ , M _b ⁺ ), preferably −20 to 120 ° C., more preferably −10 to 100 ° C., and more preferably 0 to 80 ° C is most preferred.
M _b salt object of AMA may or may be separated without particular operation, suitable organic solvents (e.g., diethyl ether, toluene, chloroform and the like) extracted with, it may be separated.

Furthermore, a method for converting an AMA salt obtained by hydrolysis with a base into α-allyloxymethylacrylic acid (AMA carboxylic acid) and subsequently producing a salt of another cation by a direct method is described.
This process is divided into a step of obtaining an AMA carboxylic acid (previous step) and a step of converting it to a salt of another cation by a direct method performed subsequently (post step).
The preceding step is a step of treating the AMA salt with an acid (preferably a strong acid) in the presence of water, and it is simple and most preferable to mix the aqueous solution of the AMA salt and the strong acid. Preferred examples of the acid include sulfuric acid, nitric acid, hydrochloric acid, organic sulfonic acid (p-toluenesulfonic acid and the like), trifluoroacetic acid, phosphoric acid, and acidic ion exchange resins (particularly sulfonic acid type are preferable).
The reaction temperature is preferably −20 to 120 ° C., more preferably −10 to 100 ° C., and most preferably 0 to 80 ° C.
If necessary, the AMA carboxylic acid may be isolated and purified before the subsequent step. Although it does not specifically limit as an isolation / purification method, For example, the method of extracting and isolate | separating with a suitable organic solvent (For example, diethyl ether, toluene, chloroform etc.) is mentioned.

The post-stage process is a kind of neutralization reaction, and the AMA carboxylic acid obtained in the pre-stage process may be mixed with a base corresponding to the target cation. The reaction temperature is preferably −20 to 120 ° C., more preferably −10 to 100 ° C., and most preferably 0 to 80 ° C.
In the direct method, the target AMA salt is hydrolyzable and difficult to synthesize in an aqueous solution, or the AMA salt is water-soluble and difficult to extract, or the base (for example, metal hydroxide) , Amine, phosphine, etc.) are particularly effective when readily available.

The diene carboxylate in the present invention can contain an anion other than the diene carboxylate anion and a neutral molecular ligand. Such a salt can be easily obtained, for example, by hydrolysis with the above-mentioned base, metathesis method or direct method. To obtain a salt containing other carboxylate anions, e.g., in the hydrolysis step with a base or an acid, it is sufficient to coexist other carboxylic acid ester or carboxylic acid nitriles, also in double decomposition method, AMA of M _a What is necessary is just to make the Ma salt of other carboxylic acid coexist with _a salt. Further, in the direct method, other carboxylic acids may coexist. Other anions X ^- (e.g. sulfate ion, nitrate ion, halogen ion, etc.) in order to obtain a salt containing, for example, in double decomposition method, M _b salt as an anion X ^- and the multivalent M _b ions using a salt (e.g. divalent salt _M b _{(X) 2),} the amount of _{M a} salt of AMA to use (i.e. the amount of AMA ions), may be less than the equivalent of valence of _{M b.} In order to coordinate the neutral molecular ligand, the target neutral molecular ligand may be present in the reaction solution. For example, in the hydrolysis method, metathesis method or direct method, A neutral molecular ligand may be used as a solvent or added to the reaction solution.
Further, as a method for obtaining a diene carboxylate, a method of mixing two or more kinds of salts is also preferable, and a complex type salt is particularly easily obtained. For example, it is possible to obtain a composite M _a salt alone, acrylic acid -AMA carboxylic acid corresponding to the mixing ratio for mixing the M _a salt and AMA M _a salt of acrylic acid. Similarly, _M a -M _b composite salt of AMA carboxylic acid is obtained if you mixed with _{M a} salt and AMA _{M b} salt of the AMA.

When applying to the surface of a material with poor properties, it is preferable to lower the surface tension of the aqueous composition to such an extent that the surface of the material can be sufficiently wetted. Therefore, when the aqueous composition is used for application to the surface of a material having poor water absorption, it may further contain a compound having a lipophilic part and a hydrophilic part classified as a leveling agent or surfactant.
