(Adhesive material)
The adhesive material of the present embodiment is an adhesive material that satisfies the following formula 1.
Formula 1: 20 ° C. ≦ T (1 MPa) −T (10 MPa)
In Formula 1, T (1 MPa) represents a temperature at which the viscosity becomes 10 ⁴ Pa · s at an applied pressure of 1 MPa, measured using a flow tester, and T (10 MPa) was measured using a flow tester. Represents the temperature at which the viscosity becomes 10 ⁴ Pa · s at an applied pressure of 10 MPa.

The adhesive material of this embodiment is a novel adhesive material that is different from conventional adhesive materials.
When bonding a base material using the conventional adhesive material, it is necessary to heat the adhesive material together with the base material. On the other hand, the adhesive material of the present embodiment is bonded by pressure (also referred to as pressure bonding) when the substrate is bonded. That is, the adhesive material of the present embodiment reduces the heating amount to the base material at the time of bonding, or crimps without heating at all, so compared with the conventional adhesive material, Excellent energy saving, cost for bonding, bonding speed, and production of pressure-bonded printed matter.

Further, the adhesive material of the present embodiment is suitably used for producing a press-bonded printed material.
In the present embodiment, the pressure-bonded printed material refers to a printed material formed by bonding a folded base material, or a printed material formed by bonding two or more base materials.
The pressure-bonded printed material is not particularly limited, and examples thereof include a postcard-sized pressure-bonded printed material (hereinafter also referred to as “pressure-bonded postcard”).
Crimp postcards are available at the same rate as regular postcards. For this reason, the pressure-bonded postcard is used in place of the sealed letter, and the concealed description can be viewed by peeling. Crimp postcards are delivered concealing the items described. After delivery, the addressee peels off the concealed sheet and reads the written information. By using a crimped postcard, a confidential document is sent in the form of a postcard instead of a sealed letter. As a conventional technique, a method such as applying a liquid adhesive material or sandwiching an adhesive sheet is used to complete the postcard for posting by printing the character information inside the folded folded postcard. Has been.
In the production of a pressure-bonded printed matter, the placement of the adhesive material before printing of character information or the like is also referred to as a “front paste method”, and the placement of the adhesive material after printing is also referred to as a “rear paste method”.

The following points can be cited for existing crimped postcards.
Conventional crimped postcard paper generally has a expiration date of, for example, 3 to 6 months.
In the front paste method, when the printing rate increases, the adhesive force decreases, and thus there is a limitation on the printing area.
Further, in the front paste method, the image forming apparatus and the formed image may be contaminated by the glue detached from the base material during image formation.
The adhesive force may change greatly depending on the storage conditions and a significant change in humidity.
In a pressure-bonded postcard manufactured by a front paste or a back paste system, gloss unevenness may occur depending on the image density.
The post-glue method requires large-scale equipment and advanced technology, and requires large capital investment.
A film crimping method in which a special film for crimping is sandwiched between adhesive surfaces while applying heat while applying heat, or a UV (ultraviolet) curable varnish is applied to the adhesive surface, and UV is irradiated to cure and heat is applied. Since the UV varnish method for pressure bonding uses heat to perform pressure bonding, it takes time for pressure bonding.
Mail sealers used for film pressure bonding or UV varnish pressure bonding are expensive.
Since the film pressure bonding method uses a film, the operation cost is higher than other methods.
The UV varnish method further requires a large-scale UV varnish coating apparatus, and is unsuitable for production of a small amount of various products from the viewpoint of cost.

Most conventional adhesives, particularly powder adhesives (hereinafter also referred to as “toner adhesives”), are systems in which the toner adhesive is melted by heat energy and pressure is used in combination.
For example, in the production of a crimping postcard, when an adhesive material on a mating surface of a bi-fold or tri-fold postcard is to be thermocompression bonded by a hot roller device or the like, the thermal energy is transferred to the adhesive material via a postcard. Become. Since the thermal conductivity of the postcard is small, it acts as a thermal resistor, so melting the adhesive material requires a longer heating time than melting the surface adhesive material. For this reason, the pressure-bonding processing speed is reduced. When the adhesive material is thermally melted via a postcard, it usually requires, for example, 5 to 10 times longer heating time than the case where the adhesive material on the postcard surface is melted. Decreases to 1/5 to 1/10. In addition, when heat energy is applied to the postcard, curling or other deformation occurs in the postcard, or when an image of toner is recorded on the surface of the postcard in advance, the toner on the surface is dissolved, resulting in hot offset (high temperature offset). ) May occur.
When the adhesive material of the present embodiment is used, the heating offset of the substrate is suppressed by reducing the amount of heating of the base material at the time of pressing, or by pressing without heating at all.

In addition, the apparatus used for arranging and pressure-bonding the adhesive material according to the present embodiment is a relatively small apparatus as compared with conventional large-scale post-glue application apparatuses and UV varnish application apparatuses. For example, when using toner to be described later as the adhesive material, a small toner forming unit is used as the apparatus, and the apparatus can be downsized. Since conventional equipment requires large-scale equipment such as exhaust equipment, the users are limited to printing companies and specialists. On the other hand, it is used to place and crimp the adhesive material according to this embodiment. If it is a device to be used, it has the advantage that it is installed and used in an office, and there is no need for a person who operates the device exclusively.
In the adhesive material according to the present embodiment, plain paper or a special base material is used as a base material, not a special paper pre-applied with glue. In particular, the adhesive material according to the present embodiment reduces the amount of heating of the base material at the time of bonding compared to conventional adhesive materials, or is pressure-bonded by the action of pressure without applying heat at all. It is also used for inferior resin films.
Furthermore, since the adhesive material according to the present embodiment is stable against environmental changes, the adhesive force is less affected by humidity than the conventional adhesive materials, and the environmental stability is high. Furthermore, the expiration date is longer than that of conventional adhesive materials.
In addition, the adhesive material according to the present embodiment reduces the heating amount of the base material at the time of bonding or does not apply heat at all, and is pressure-bonded by pressure. , Energy saving and faster production (increased production) are realized.

As described above, the adhesive material according to this embodiment is high-speed, low-cost, high-quality, and on-demand printing (printing with different publication information) from a small number of parts compared to the conventional postcard pressure bonding method. We propose a method that can realize printing up to
That is, the present embodiment relates to a new method different from the conventional pressure bonding method and an adhesive material that realizes the new method.
The adhesive material according to the present embodiment is suitably used as an adhesive material for producing a press-bonded printed material.
One embodiment of a typical method for producing a pressure-bonded printed material is described in the following items 1 to 4.
1. An adhesive material is disposed on the surface of the image area and the non-image area as a pressure-sensitive adhesive on the base material on which the image is recorded by an electrophotographic method.
2. The arranged adhesive material is presupposed by pressure. (Adhesive material is fluidized by the action of pressure to form an adhesive material layer)
3. The substrate is bent so that the surface on which the adhesive material layer is formed is on the inside.
4). The bent base material is crimped by the action of only pressure using a crimping apparatus. (The adhesive material layer is fluidized and joined again by the action of pressure)
Hereinafter, the details of the adhesive material according to the present embodiment will be described.

<Plastic behavior against pressure>
The adhesive material according to the present embodiment satisfies the following formula (1), exhibits plastic behavior with respect to pressure even when not heated, and exhibits fluidity under a pressure higher than a predetermined pressure.
Formula 1: 20 ° C. ≦ T (1 MPa) −T (10 MPa)
In Formula 1, T (1 MPa) represents a temperature at which the viscosity becomes 10 ⁴ Pa · s at an applied pressure of 1 MPa, measured using a flow tester, and T (10 MPa) was measured using a flow tester. Represents the temperature at which the viscosity becomes 10 ⁴ Pa · s at an applied pressure of 10 MPa.

The temperature difference represented by T (1 MPa) −T (10 MPa) (hereinafter also referred to as “temperature difference ΔT”) is 20 ° C. or higher, preferably 40 ° C. or higher, more preferably 50 ° C. or higher, and 60 ° C. or lower. Further preferred. When the temperature difference ΔT is 20 ° C. or more, the plastic behavior with respect to pressure is sufficient, and excellent adhesion performance is exhibited.
Further, the temperature difference ΔT is preferably 120 ° C. or less, more preferably 100 ° C. or less, and further preferably 80 ° C. or less. When the temperature difference ΔT is 120 ° C. or less, the adhesive material does not become too soft, and is prevented from dropping or moving from the place where the adhesive material is disposed.
The value of T (10 MPa) is preferably 140 ° C. or lower, preferably 130 ° C. or lower, and more preferably 120 ° C. or lower. If the value of T (10 MPa) is 140 ° C. or less, it is easy to reduce the amount of heating of the base material during bonding using normal pressure applying means, or to bond only by pressure without heating. It becomes.
The value of T (10 MPa) is preferably 60 ° C. or higher, preferably 65 ° C. or higher, and more preferably 70 ° C. or higher. When the value of T (10 MPa) is 60 ° C. or higher, the adhesive material after bonding is cured and the adhesive strength is excellent.
The temperature difference ΔT is measured by a method using a flow tester. Examples of the flow tester include a flow tester CFT-500 manufactured by Shimadzu Corporation.
A specific method for measuring the temperature difference ΔT is as follows.
The adhesive material is compressed and solidified to produce a pellet-like sample. The prepared sample is set in a flow tester, and the measurement temperature is gradually heated from 50 ° C. within a range of 50 ° C. to 150 ° C. (temperature increase rate of + 1 ° C./min), and a predetermined extrusion pressure is applied. Below, the viscosity of the sample is measured. The applied pressure is fixed at 1 MPa, and the viscosity with respect to the temperature at 1 MPa is measured. From the obtained viscosity graph, the temperature T (1 MPa) when the viscosity becomes 10 ⁴ Pa · s at an applied pressure of 1 MPa is determined. T (10 MPa) is determined by the same method as T (1 MPa) except that the applied pressure is set to 10 MPa. A temperature difference ΔT (T (1 MPa) −T (10 MPa)) is calculated by taking a difference from the obtained T (1 MPa) and T (10 MPa).

The adhesive material according to the present embodiment is preferably particulate from the viewpoint of applicability to the substrate.
The adhesive material according to this embodiment may be disposed on the base material as an adhesive material dispersion in which the adhesive material is dispersed in a solvent, or the particulate adhesive material may be disposed on the base material without using a solvent. .
The adhesive material according to this embodiment is preferably an electrostatic image developing toner (hereinafter also simply referred to as “toner”).

When the adhesive material is disposed on the base material as an adhesive material dispersion, the solvent for dispersing the adhesive material is not particularly limited, and a known solvent can be used. From the viewpoint of low solubility of the adhesive material, water is preferable.
When the adhesive material is disposed on the substrate as an adhesive material dispersion, the volume average particle size of the adhesive material is preferably 1 μm to 50 μm, more preferably 2 μm to 30 μm, and even more preferably 3 μm to 25 μm.
The volume average particle diameter is measured by the same method as described later when the adhesive material is an electrostatic charge image developing toner.

When the adhesive material according to this embodiment is a toner for developing an electrostatic charge image, it can be applied to the base material by an electrophotographic method. It becomes easy to design in detail according to.
As the toner, a particulate adhesive material may be used as it is, or an externally added toner in which an external additive is further added to the particulate adhesive material. The particulate adhesive material in the present embodiment is also referred to as “adhesive material particle”, and the adhesive material particle in the case where the adhesive material in the present embodiment is toner is also particularly referred to as “toner particle”.

<Baro Plastic>
As the adhesive material of this embodiment, an adhesive material containing a resin is preferable, and an adhesive material containing baroplastic is more preferable.
Below, the preferable two forms are demonstrated and demonstrated about the baroplastic used for this embodiment.

[First Embodiment]
The adhesive material according to this embodiment includes at least two kinds of resins (also referred to as “binder resins”) having different glass transition temperatures (Tg) from the viewpoint of easily exhibiting plastic behavior when a pressure is applied. Is preferred. When the adhesive material according to the present embodiment includes at least the two kinds of resins, the adhesive material easily forms a phase separation structure. Therefore, it is considered that the adhesive material tends to exhibit fluidity under a pressure higher than a predetermined pressure, and excellent pressure fixing performance is easily exhibited.

  When the adhesive material which concerns on this embodiment contains 3 or more types of resin, the glass transition temperature of at least 2 types of resin should just differ among 3 or more types of resin.

In the adhesive material according to this embodiment, the glass transition temperatures of the two resins are preferably different by 30 ° C. or more, and more preferably different by 35 ° C. or more. When the glass transition temperatures of the two types of resins are different by 30 ° C. or more, the adhesive material containing these two types of resins is easily fixed at a lower pressure.
The adhesive material according to the present embodiment may include three or more kinds of resins, and in that case, it is preferable that two of them have the above relationship.

  Of the two types of resins, the content of the resin having a high glass transition temperature relative to the total mass of the two types of resins is preferably 5% by mass to 70% by mass, and more preferably 10% by mass to 60% by mass. 20 mass% or more and 50 mass% or less is still more preferable. When the content of the resin having a high glass transition temperature is 5% by mass or more and 70% by mass or less, adhesion at a low pressure is easily performed.

  When the adhesive material according to the present embodiment includes three or more types of resins, the content of the two types of resins with respect to the total mass of the three or more types of resins is 80% by mass or more and 99% by mass or less. It is preferably 85% by mass to 95% by mass, and more preferably 85% by mass to 95% by mass. When the content of the two kinds of resins is 80% by mass or more and 99% by mass or less, it is easy to perform pressure bonding at a low pressure.

  At least one of the two kinds of resins having different glass transition temperatures preferably has a glass transition temperature of 40 ° C or higher, more preferably 45 ° C or higher, and still more preferably 50 ° C or higher. When the glass transition temperature is 40 ° C. or higher, an adhesive material excellent in storage stability is easily obtained.

  The content of the resin having a glass transition temperature of 40 ° C. or higher is preferably 5% by mass or more and 70% by mass or less, and preferably 10% by mass or more and 60% by mass or less with respect to the mass of two types of resins having different glass transition temperatures. Preferably, 20 mass% or more and 50 mass% or less are more preferable.

  Of the two types of resins described above, the higher glass transition temperature is preferably 40 ° C. or higher, preferably 40 ° C. or higher and lower than 60 ° C., more preferably 40 ° C. or higher and lower than 55 ° C. When the temperature is less than 60 ° C., it is easy to perform adhesion by pressure at normal temperature (in-machine temperature of 50 ° C. or less).

  Of the two types of resins, the lower temperature of the glass transition temperature is preferably less than 10 ° C, preferably from -100 ° C to less than 10 ° C, and more preferably from -80 ° C to less than 10 ° C. When the temperature is less than 10 ° C., it is easy to perform pressure bonding at low pressure.

  The resin composition according to this embodiment may include three or more types of resins, in which case the glass transition temperatures of the two types of resins are different by 30 ° C. or more, and at least one of the glass transitions thereof. The temperature is preferably 40 ° C. or higher.

The aspect described above for “two types of resins having different glass transition temperatures” is also applicable to “two types of resins having different melting temperatures” and “amorphous resins and crystalline resins having different glass transition temperatures and melting temperatures”. It may be true.
The glass transition temperature can be controlled mainly by the density of rigid units such as aromatic rings and cyclohexane rings in the main chain of the resin. That is, if the density of methylene group, ethylene group, oxyethylene group, etc. in the main chain is high, the glass transition temperature decreases, and if the aromatic ring or cyclohexane ring increases, it increases. Furthermore, increasing the density of side chains such as aliphatic reduces the glass transition temperature. By taking these into consideration, resins having various glass transition temperatures can be obtained.
Similarly, the melting temperature can be controlled by the density of rigid units.

Hereinafter, when the two types of resins are two types of amorphous resins having different glass transition temperatures, the higher glass transition temperature is referred to as “high Tg resin”, and the lower glass transition temperature is referred to as “low Tg”. This will be described as “resin”.
When the two types of resins are two types of crystalline resins having different melting temperatures, the higher melting temperature is referred to as “high melting point resin” and the lower melting temperature is referred to as “low melting point resin”. To do.
When the two kinds of resins are an amorphous resin and a crystalline resin having different glass transition temperatures and melting temperatures, and the glass transition temperature is higher than the melting temperature, they are referred to as “high Tg resin” and “low melting point resin” When the transition temperature is lower than the melting temperature, it will be described as “low Tg resin” or “high melting point resin”.

  As an aspect in which the adhesive material according to the present embodiment includes a high Tg resin and a low Tg resin, an aspect capable of forming a phase separation structure that easily exhibits plastic behavior when pressure is applied is preferable. Examples of such an embodiment include an adhesive material containing a mixture containing both a high Tg resin and a low Tg resin; an adhesive material containing a resin in which a high Tg resin and a low Tg resin form a sea-island structure; And an adhesive material containing resin particles that form a core / shell structure with a low Tg resin.

Even when the adhesive material according to the present embodiment is an aspect including a high melting point resin and a low melting point resin, an aspect including a high Tg resin and a low melting point resin, and an aspect including a low Tg resin and a high melting point resin, Except having changed the kind of resin, it is the same as that of the aspect containing the above-mentioned high Tg resin and low Tg resin.
An example of the aspect of the adhesive material according to the present embodiment will be described in more detail below by taking an aspect including a high Tg resin and a low Tg resin as an example.

  As a mixture containing both the high Tg resin and the low Tg resin, a resin particle dispersion in which a resin particle dispersion in which particles of a high Tg resin are dispersed and a resin particle dispersion in which particles of a low Tg resin are dispersed is mixed. A powder obtained by mixing a powder containing a high Tg resin and a powder containing a low Tg resin; a solid obtained by melting and mixing a solid containing a high Tg resin and a solid containing a low Tg resin Thing; etc. are mentioned.

  A resin in which a high Tg resin and a low Tg resin form a sea-island structure forms a phase separation structure in which an island phase exists in the sea phase. The resin forming the sea-island structure may have a high Tg resin as a sea phase and a low Tg resin as an island phase, a high Tg resin as an island phase, and a low Tg resin as a sea phase. The high Tg resin is preferably the sea phase and the low Tg resin is preferably the island phase.

  The sea-island structure of the resin contained in the adhesive material is confirmed by the following method. After embedding the adhesive material in an epoxy resin, prepare a section with a diamond knife or the like, stain the prepared section with osmium tetroxide in a desiccator, observe the stained section with a transmission electron microscope, Check the resin structure. Here, the sea phase and the island phase of the sea-island structure are distinguished by shading caused by the degree of resin staining with osmium tetroxide.

  The major axis of the island phase is preferably 150 nm or less. When the high Tg resin is the sea phase and the low Tg resin is the island phase, the low Tg resin phase that is the island phase is preferably finely distributed. In such a case, the diameter of the island phase is preferably 150 nm or less, preferably 5 nm or more. 150 nm or less is more preferable, 50 nm or more and 140 nm or less is more preferable, and 100 nm or more and 130 nm or less is particularly preferable. When the diameter of the island phase is 150 nm or less, the pressure plastic behavior is likely to be sufficient, and fixing is facilitated during pressure fixing. When the island phase has a diameter of 5 nm or more, a high Tg resin and a low Tg resin are not mixed and dissolved, and it is easy to form a sea-island structure, and blocking is caused by plasticizing even at room temperature without pressure. Is less likely to occur.

  The major axis of the island phase is calculated by the following method. After embedding the adhesive material in an epoxy resin, a section is prepared with a diamond knife or the like, and the obtained section is observed with a transmission electron microscope. The major axis of the island phase is calculated by arbitrarily selecting 100 island phases observed in the section and calculating the average major axis using a Luzex image analyzer.

The ratio of the mass of the resin that forms the island phase to the mass of the resin that forms the sea phase is preferably 0.25 or more.
In order to develop an appropriate pressure plastic behavior, for example, when the high Tg resin is a sea phase and the low Tg resin is an island phase, the mass ratio of the low Tg resin is 0. 0 relative to the mass of the high Tg resin. 3 or more are preferable, 0.4 or more are more preferable, and 0.5 or more are still more preferable.
The mass ratio of the low Tg resin is preferably less than 1.5 with respect to the mass of the high Tg resin. When it is less than 1.5, plasticization at normal temperature hardly occurs.

  As the resin used for forming the sea-island structure, for example, an addition polymerization resin or a polycondensation resin is preferable.

The resin particles in which the high Tg resin and the low Tg resin form a core / shell structure are resin particles having a core part (core particle) and a coating layer (shell layer) covering the core part.
Preferred examples of the baroplastic include a resin obtained by aggregating resin particles in which a high Tg resin and a low Tg resin form a core / shell structure.

  The high Tg resin may be the core and the low Tg resin may be the coating layer, or the high Tg resin may be the coating layer and the low Tg resin may be the core, but the high Tg resin is the coating layer and the low Tg resin. Is preferably a core.

  The diameter of the core is preferably 10 nm or more and 200 nm or less, and more preferably 20 nm or more and 150 nm or less. The thickness of the coating layer is preferably 10 nm to 100 nm, and preferably 20 nm to 80 nm.

  The core / shell structure is confirmed by the following method. After embedding the adhesive material in an epoxy resin, a section is prepared with a diamond knife or the like, and the obtained section is observed with a transmission electron microscope to confirm the structure of the resin particles.

As the resin used for forming the core / shell structure, for example, an addition polymerization resin and a polycondensation resin are preferable.

[Second Embodiment]
The adhesive material according to the present embodiment preferably contains a resin having two glass transition temperatures in one molecule from the viewpoint of easily exhibiting plastic behavior when a pressure is applied. When the adhesive material according to the present embodiment includes the resin, the adhesive material easily forms a phase separation structure. Therefore, it is considered that the adhesive material easily exhibits fluidity under a pressure higher than a predetermined pressure, and excellent adhesive performance is easily exhibited.

  In the resin having two glass transition temperatures in one molecule, the two glass transition temperatures are preferably different by 30 ° C. or more, more preferably 50 ° C. or more, from the viewpoint that the adhesive material is easily bonded at a lower pressure. .

  When the resin has two glass transition temperatures in one molecule, the resin is preferably a block copolymer or a graft copolymer of resins having different glass transition temperatures. In this case, a segment derived from a resin having a higher glass transition temperature is referred to as a “high Tg segment”, and a segment derived from a resin having a lower glass transition temperature is referred to as a “low Tg segment”.

  The proportion of the high Tg segment in the resin is preferably 5% by mass to 70% by mass, and more preferably 10% by mass to 60% by mass. When the ratio of the high Tg segment is 5% by mass or more and 70% by mass or less, fixing at a low pressure is easily performed, and the fixing degree of the image is not easily deteriorated.

  The resin preferably has a glass transition temperature of 40 ° C. or higher, more preferably 45 ° C. or higher, and still more preferably 50 ° C. or higher. When the glass transition temperature is 40 ° C. or higher, an adhesive material excellent in storage stability is easily obtained.

As long as the block copolymer exhibits a plastic behavior when a pressure is applied, the connecting form of the constituent segments may be any.
Examples of the block copolymer include AB type, ABA type, BAB type, (AB) n type, (AB) nA type, B (AB) n, where A is a high Tg segment and B is a low Tg segment. Examples thereof include block copolymers such as molds.

  The phase-separated structure formed by the block copolymer has a thermodynamically most stable structure depending on the type and molecular weight of the constituent segments. In general, in a copolymer composed of a C segment and a D segment, Regardless of the type of connection, it depends only on the C / D composition ratio. As the C / D ratio increases, C is a spherical domain, D is a matrix (C sphere D matrix) (sea island), and C is a rod-like domain. Is a matrix (cylinder), C and D are nested (gyroid), C / D alternating layers (lamellar), D is a rod-like domain, C is a matrix (cylinder), D and C are nested (gyroid), D Is a spherical domain and C systematically changes into a matrix (D sphere C matrix) (sea island).

  However, when an adhesive material is produced by a wet method, the phase separation state is arbitrarily controlled depending on the solvent used, the drying speed, and the like. For example, even when the C / D ratio is large and thermodynamically the D sphere C matrix is used, if a solvent that is a good solvent for D and a poor solvent for C is selected as the solvent, the C sphere D matrix is selected. A structure is obtained.

  Moreover, when the good solvent of both C and D is used and a solvent is removed rapidly, the phase-separation structure (modulation structure) frozen in the spinodal decomposition state will be obtained. In addition, when a polymer compatible with only D is added to a copolymer having a large C / D ratio and thermodynamically taking D sphere C matrix, C is compatible with only sphere, D and D only. A phase separation structure in which the polymer serves as a matrix can also be obtained.

  The size of the repeating unit of the phase separation structure formed by the block copolymer increases as the molecular weight of the block copolymer increases. The weight average molecular weight of the block copolymer is preferably from 3,000 to 500,000, preferably from 5,000 to 400,000, and more preferably from 6,000 to 300,000.

This sea-island structure is the same as the sea-island structure formed by the high Tg resin and the low Tg resin described above.

  The block copolymer or graft copolymer having a high Tg segment and a low Tg segment can take the form of a resin particle forming a core / shell structure. The core / shell structure is the same as the core / shell structure formed by the high Tg resin and the low Tg resin described above.

  In addition, the method for producing resin particles in which the block copolymer or graft copolymer forms a core / shell structure is, for example, by producing aggregated particles that become a core portion by an emulsion aggregation method, and then forming a single particle on the surface of the aggregated particles. There is a method for producing the resin particles by polymerizing a monomer to form a shell layer.

The synthesis method of the block copolymer or graft polymer is as follows: “4th edition Experimental Chemistry Course 28 Polymer Synthesis (Maruzen, 1992)”, “Macromonomer Chemistry and Industry (IPC, 1990)”, “High Molecular Compatibilization and Evaluation Technology (Technical Information Society, 1992) "," New Polymer One Point 12 Polymer Alloy (Kyoritsu, 1988) "," Angew. Macromol. Chem., 143, pp.1-9 (1986) ) "," Journal of the Adhesion Society of Japan, 26, pp. 112-118 (1990) "," Macromolecules, 28, pp. 4893-4898 (1995) "," J. Am. Chem. Soc., 111, pp. 7641-7643 (1989) "," JP-A-6-83077 ", etc., any appropriate synthesis method described in the literature may be used.

It is the same as the method. Moreover, the measuring method of the glass transition temperature and the melting temperature of an adhesive material of a combination of other resins, such as an adhesive material containing a high Tg resin and a low melting point resin, is the same as that described above.

Etc. may be produced. Among these methods, from the viewpoint of easy control of the structure, average particle size, particle size distribution, and the like of the adhesive material, a so-called chemical production method such as an emulsion aggregation method, a dissolution suspension method, a suspension polymerization method, or a PxP method. The emulsion aggregation method and the dissolution suspension method are more preferable.
Hereinafter, an emulsion aggregation method and a dissolution suspension method will be described as typical production methods.

<Emulsion aggregation method>
In the present embodiment, the emulsification aggregation method fuses the aggregate with an emulsification step of emulsifying the raw material constituting the adhesive material to form resin particles (emulsion particles), an aggregation step of forming an aggregate containing the resin particles, and the aggregate. And a fusion step.

[Emulsification process]
For example, the resin particle dispersion may be produced by applying a shearing force to a solution obtained by mixing an aqueous medium and a binder resin with a disperser. At that time, particles may be formed by heating to lower the viscosity of the resin component. A dispersant may be used for stabilizing the dispersed resin particles.
Furthermore, if the resin is oily and dissolves in a solvent having a relatively low solubility in water, the resin is dissolved in these solvents and dispersed in water together with a dispersant and a polymer electrolyte, and then heated or decompressed. By evaporating the solvent, a resin particle dispersion is produced.

  In the present embodiment, it is preferable to use the aforementioned baroplastic as the binder resin used in the emulsification step.

Examples of the dispersant used in the emulsification step include water-soluble polymers such as polyvinyl alcohol, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, sodium polyacrylate, and sodium polymethacrylate; sodium dodecylbenzenesulfonate, Anionic surfactants such as sodium octadecyl sulfate, sodium oleate, sodium laurate, potassium stearate, cationic surfactants such as laurylamine acetate, stearylamine acetate, lauryltrimethylammonium chloride, amphoteric such as lauryldimethylamine oxide Ionic surfactant, polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene Surfactants such as nonionic surfactants such as alkyl amines; and the like are; tricalcium phosphate, aluminum hydroxide, calcium sulfate, calcium carbonate, inorganic salts such as barium carbonate.

  Examples of the disperser used for preparing the emulsion include a homogenizer, a homomixer, a pressure kneader, an extruder, and a media disperser. As the size of the resin particles, the average particle size (volume average particle size) is preferably 1.0 μm or less, more preferably in the range of 60 nm to 300 nm, and still more preferably in the range of 150 nm to 250 nm. . If it is less than 60 nm, the resin particles become stable particles in the dispersion, and thus aggregation of the resin particles may be difficult. On the other hand, if it exceeds 1.0 μm, the cohesiveness of the resin particles is improved and it becomes easy to produce adhesive material particles, but the particle size distribution of the adhesive material particles may be widened.

  In preparing the release agent dispersion, the release agent is dispersed in water together with an ionic surfactant, a polymer electrolyte such as a polymer acid or a polymer base, and then heated to a temperature equal to or higher than the melting temperature of the release agent. Dispersion treatment is performed using a homogenizer or a pressure discharge type disperser to which a strong shearing force is applied while heating. Through the above treatment, a release agent dispersion is obtained. During the dispersion treatment, an inorganic compound such as polyaluminum chloride may be added to the dispersion. Preferable inorganic compounds include, for example, polyaluminum chloride, aluminum sulfate, highly basic polyaluminum chloride (BAC), polyaluminum hydroxide, aluminum chloride and the like. Of these, polyaluminum chloride and aluminum sulfate are preferred. The release agent dispersion is used in the emulsion aggregation method, but the release agent dispersion may also be used when the adhesive material is produced by suspension polymerization.

When the volume average particle diameter is 100 nm or more, the release agent component is generally easily incorporated into the adhesive material, although it is influenced by the properties of the binder resin used. Moreover, when it is 500 nm or less, the dispersion state of the release agent in the adhesive material is improved.

  For the preparation of the colorant dispersion, a known dispersion method can be used. For example, a general dispersion means such as a rotary shear type homogenizer, a ball mill having a medium, a sand mill, a dyno mill, or an optimizer can be employed. Is not to be done. The colorant is dispersed in water together with a polymer electrolyte such as an ionic surfactant, a polymer acid, or a polymer base. The volume average particle diameter of the dispersed colorant particles may be 1 μm or less, but if the range is 80 nm or more and 500 nm or less, the dispersion of the colorant in the adhesive material is good without impairing the cohesiveness. preferable.

Inorganic metal salt polymers are more suitable.
In the present embodiment, it is preferable to use a polymer of a tetravalent inorganic metal salt containing aluminum in order to obtain a narrow particle size distribution.

[Fusion process]
In the fusion step, the agglomeration is stopped by increasing the pH of the suspension of the aggregated particles to a range of 3 to 9 under the stirring conditions in accordance with the aggregation step, and the glass transition temperature is higher than the glass transition temperature of the resin. The aggregated particles are fused by heating at a temperature. The heating time may be performed to the extent that fusion is performed, and may be performed for about 0.5 hour to 10 hours.

Cool after fusion to obtain fused particles. Further, in the cooling step, crystallization may be promoted by reducing the cooling rate in the vicinity of the glass transition temperature (range of glass transition temperature ± 10 ° C.) of the resin, so-called slow cooling.
