TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cosmetic material which has abrasion resistance and scratch resistance (prevents damage to a contact object itself), and which can also express a gloss mat design (surface gloss change pattern) and a pseudo three-dimensional effect.
[0002]
[Prior art]
Cosmetic materials made up of various base materials such as paper, resin sheets, and board materials are used for various purposes such as building interior materials and fittings. Is often provided with a resin layer of a curable resin such as a two-component curable resin or an ionizing radiation curable resin. Further, in order to further improve the abrasion resistance, the resin layer contains a hard inorganic powder such as alumina or silica as a lubricant (see Japanese Patent No. 2740943).
[0003]
On the other hand, in some cases, a gloss mat design (surface gloss change pattern) is required as a design expression of a cosmetic material. The gross mat design can also express a pseudo three-dimensional effect, and for example, can also simulate the unevenness of a wood grain conduit pattern. The decorative material 20 shown in the sectional view of FIG. 2 is an example of a decorative material having such a gloss mat design. That is, in the decorative material 20 of FIG. 1, a solid pattern layer 22 expressing a solid pattern and a pattern layer 23 expressing a pattern pattern are sequentially provided on a base material 21, and then a sealing resin layer 24 is formed on the entire surface. In this configuration, a matte resin layer 25 containing a matting agent is provided by expressing a wood grain conduit portion, and a wear-resistant resin layer 26 containing a lubricant a is provided on the entire surface as an outermost surface layer. . The matte resin layer 25 itself is not the outermost layer, but the abrasion-resistant resin layer 26 above the matte resin layer is partially glossy due to the matting agent contained in the matte resin layer immediately below. By penetrating into the decoloring resin layer, the surface becomes uneven and becomes a delustering part m with reduced luster. The gloss matt design is expressed by the surface of the abrasion-resistant resin layer 26 having a partially reduced gloss, and the matte portion m is a portion where the matte resin layer 25 is directly below and the matte resin layer 25 is not directly below. The portion becomes the glossy portion g. With such a configuration, a grout mat design synchronized with the conduit pattern of the pattern layer provides a decorative material having a pseudo three-dimensional effect on the conduit pattern.
[0004]
[Problems to be solved by the invention]
However, in the decorative material having the structure as shown in FIG. 2, the wear-resistant resin layer 22 has the outermost surface, so that the wear resistance is certainly good. However, the wear resistance performance of the wear-resistant resin layer containing the anti-wear agent is not only the hardness of the resin, but also the particle component that jumps out of the surface of the layer due to the fact that the hard anti-wear agent itself contains it. In general, alumina powder having a large particle diameter and the like are used as an anti-wear agent. For this reason, roughness appears on the surface of the wear-resistant resin layer, and other articles in contact with the surface of the decorative material are damaged, resulting in poor scratch resistance. That is, in the environment in which the cosmetic material is used, the object placed on the surface of the cosmetic material is easily scratched by the surface of the cosmetic material. In addition, the gloss matte pattern on the surface is obtained by partially forming the matte resin layer below it through a wear-resistant resin layer in a pattern shape, so the contour of the pattern is absolutely sweet and sharp No synchronizing effect is obtained. Therefore, for example, in the above-described design expression of the pseudo three-dimensional effect of the conduit pattern, the three-dimensional effect is poor. In this regard, if the wear-resistant resin layer is laminated thinly, the synchronizing effect is improved, but there is a problem that the essential wear resistance is greatly reduced.
[0005]
Therefore, a layer configuration in which the wear-resistant resin layer is on the inside and the layer for expressing the gloss mat is on the surface has been proposed. For example, in Japanese Unexamined Patent Publication No. 13-315286, a solid pattern layer 22 having a solid pattern and a pattern layer 23 having a pattern are sequentially provided on a base material 21 in this order, as in a decorative material 20 shown in the cross-sectional view of FIG. Thereafter, an abrasion-resistant matting resin layer 27 containing both the abrasion-resistant agent a and the matting agent and having both abrasion resistance and matting is provided on the entire surface, and a gloss-improving resin layer 28 is partially provided thereon. Configuration. The gloss matt design is represented by both a wear-resistant matte resin layer 27 and a gloss-enhancing resin layer 28. The matte portion m is the exposed surface of the wear-resistant matte resin layer 27, and the glossy portion g is the glossy portion. This is the part of the enhancement resin layer 28.
However, in such a configuration, since the surface of the abrasion-resistant matte resin layer is rough, when the gloss-enhancing resin layer is partially printed on the layer, the ink transfer property is poor, and The gloss enhancing resin layer cannot be partially formed in the pattern. Therefore, even if a large gloss matt design is sufficient, a fine design such as a pipe pattern is not sharp enough as a practical problem, and a sufficient design effect cannot be obtained.
[0006]
On the other hand, there is a configuration proposed in Japanese Patent Application Laid-Open No. 2001-138469 as another layer configuration in which the wear-resistant resin layer is on the inside and the layer for expressing the gloss mat is on the surface. That is, like the decorative material 20 shown in the cross-sectional view of FIG. 4, a solid pattern layer 22 having a solid pattern and a pattern layer 23 having a pattern are sequentially provided on a base material 21 in order, and then the anti-wear layer containing an anti-abrasive a is provided. The structure is such that a wear resin layer 26 is provided on the entire surface, a matte resin layer 25 is provided thereon, and a matte improving resin layer 28 is partially provided on the matte resin layer 25. The gross mat design is expressed by both the matte resin layer 25 and the matte improving resin layer 28. The matte part m is the exposed surface of the matte resin layer 25, and the matte part g is the matte improving resin layer 28. Part.
According to this configuration, as compared with the configuration of FIG. 3, the surface on which the gloss-enhancing resin layer is to be partially formed by printing is not the wear-resistant resin layer but the matte resin layer thereon, so that the ink transfer property can be improved. Has improved, and the problem of design effects based on the badness has improved. However, the matting degree of the matte resin layer is not stable, and even if the matte resin layer is thickened, it does not improve, and the design effect of the gloss mat is still insufficient.
[0007]
That is, an object of the present invention is to provide a cosmetic material having excellent abrasion resistance and scratch resistance as well as a glossy matte design on the surface.
[0008]
[Means for Solving the Problems]
Therefore, in order to solve the above-mentioned problem, the decorative material of the present invention includes a matting agent on the wear-resistant resin layer in a decorative material provided with a wear-resistant resin layer containing a lubricant on a substrate. After laminating a matte resin layer via a smoothing resin layer for smoothing the rough surface of the wear-resistant resin layer, a structure in which a gloss improving resin layer is further partially laminated on the matte resin layer is adopted. .
[0009]
With such a configuration, first, the wear resistance is obtained by the inner wear-resistant resin layer, and the gloss mat design is obtained by the matte resin layer and the gloss-enhancing resin layer provided thereon. In addition, the matte resin layer for the gloss mat design is provided on the surface of the wear-resistant resin layer with the smoothing resin layer interposed therebetween, so that the roughness of the surface of the wear-resistant resin layer is suppressed, and the matte resin layer is matted. Adjustment of the degree and partial formation of the gloss improving resin layer on the matte resin layer surface can be performed without any problem of ink transferability. Therefore, the gloss mat design has a sharp outline, and the degree of matting and the degree of gloss improvement can be easily adjusted. In addition, a deep painting feeling can be obtained. As a result, the design of the gloss mat is improved. In addition, since the surface of the wear-resistant resin layer has a smoothing resin layer, a matting resin layer, a gloss-improving resin layer, and the like, roughness of the surface of the wear-resistant resin layer is suppressed, and other articles that come into contact with the surface of the decorative material can be prevented. There is no damage and the scratch resistance is good. As a result, the decorative material can provide all of abrasion resistance, scratch resistance, and excellent gloss mat design feeling.
[0010]
In addition, the cosmetic material of the present invention has a configuration in which the smoothing resin layer further contains an extender pigment in the above configuration.
With such a configuration, the sealing effect of the smoothing resin layer is improved. As a result, the thickness of the matte resin layer can be increased, and the depth of coating can be increased.
[0011]
In addition, the decorative material of the present invention, in any one of the above constitutions, further comprises a pattern layer having a pattern synchronized with the pattern formed by the gloss improving resin layer laminated between the base material and the wear-resistant resin layer. And
With such a configuration, a gloss mat design having a higher design can be obtained. For example, a pseudo three-dimensional effect such as unevenness of a wood grain conduit pattern can be expressed. In the expression of a conduit, the non-formation part of the gloss enhancing resin layer is synchronized with the pattern of the pattern layer so that the part where the gloss-enhancing resin layer is not formed is the conduit part.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0013]
〔Overview〕
FIG. 1 is a cross-sectional view illustrating a cosmetic material 10 of the present invention in one form thereof.
The decorative material 10 illustrated in FIG. 1 is obtained by sequentially providing a solid pattern layer 2 having a full pattern and a pattern layer 3 having a pattern pattern on a substrate 1 in order, and then a wear-resistant resin layer 4 containing an anti-abrasive a. Is provided on the entire surface, after which a smoothing resin layer 5 is provided on the entire surface of the wear-resistant resin layer 4, a matting resin layer 6 is provided on the entire surface, and a pattern is partially formed on the matting resin layer 6. This is a configuration in which a gloss improving resin layer 7 is provided in a shape. The gloss matte design is expressed as a surface gloss change pattern by both the matte resin layer 6 and the gloss improving resin layer 7, and the matte portion m is the exposed surface portion of the matte resin layer 6, and the large portion g is the glossy portion. This is where the improvement resin layer 7 is formed.
[0014]
When the gloss-enhancing resin layer 7 is partially formed, if the pattern formed by the formation pattern is formed in synchronism with the pattern pattern of the pattern layer 3, the design becomes higher. For example, if the pattern is a wood-grain conduit pattern and the non-formation portion of the gloss improving resin layer 7 is formed on the pattern, a pseudo three-dimensional effect can be given to the wood-grain conduit pattern.
[0015]
It is needless to say that the solid pattern layer 2 and the pattern layer 3 can be omitted depending on the use, the design expression and the like, but it is preferable to provide the solid pattern layer 2 and the pattern layer 3 in terms of higher design.
[0016]
Hereinafter, the present invention will be described in detail for each layer in order from the substrate.
[0017]
〔Base material〕
As the base material 1, for example, in addition to sheets such as paper and resin sheets, plates, three-dimensional objects, and the like, the shape, material, and other characteristics of the base material are not particularly limited, and are conventionally known as base materials for decorative materials. Various substrates can be used according to the application.
[0018]
The material of the base material is, for example, paper, wood, metal, inorganic nonmetal (ceramic, non-ceramic ceramic, etc.), resin, and the like. Further, any of those having ink permeability (paper, nonwoven fabric, etc.) and those having no ink permeability (resin sheet, etc.) may be used. Above all, paper and resin sheets (films) are typical. If these are used as a base material, the decorative material of the present invention can be a decorative sheet.
[0019]
Further, as a fibrous base material other than a paper-based material, a non-woven fabric made of fibers such as polyester resin, acrylic resin, nylon, vinylon, and glass is also used. The nonwoven fabric may be a material to which a resin such as an acrylic resin, a styrene-butadiene rubber, a melamine resin, or a urethane resin is added (impregnated with a resin after papermaking or filled in at the time of papermaking) as in the case of the paper-based nonwoven fabric.
[0020]
As the resin base material, for example, polyethylene, polypropylene, polyolefin resin such as olefin thermoplastic elastomer, vinyl chloride resin, vinylidene chloride resin, polyvinyl alcohol, vinyl resin such as ethylene-vinyl alcohol copolymer, polyethylene resin Polyester resins such as terephthalate and polybutylene terephthalate, acrylic resins such as polymethyl methacrylate, polymethyl acrylate and polyethyl methacrylate, polystyrene, acrylonitrile-butadiene-styrene copolymer (ABS resin), cellulose triacetate, cellophane, There is a resin material such as a resin such as polycarbonate. These resins are used as sheets, plates, and three-dimensional objects.
Examples of the resin-based substrate include, for example, a thermosetting resin plate made of a thermosetting resin such as a phenol resin, a urea resin, an unsaturated polyester resin, a urethane resin, an epoxy resin, and a melamine resin, a phenol resin, and a urea resin. The so-called FRP (Fiber Reinforcement) is obtained by impregnating and curing a resin such as unsaturated polyester resin, urethane resin, epoxy resin, melamine resin, diallyl phthalate resin into glass fiber non-woven fabric, cloth, paper and other various fibrous base materials. There is also a resin plate such as a (plastic) plate.
[0021]
In addition, examples of the wood-based material include wood materials such as veneer, plywood, particle board, fiber board, and laminated wood made of cedar, cypress, oak, lauan, teak, and the like. Wood-based substrates are used as sheets, boards, and three-dimensional objects.
Examples of the metal-based substrate include metal materials such as iron, aluminum, stainless steel, and copper. Metal-based substrates are used as sheets (foil), plates, and three-dimensional objects.
Examples of the inorganic nonmetallic base material include, for example, extruded cement, slag cement, ALC (lightweight cellular concrete), GRC (glass fiber reinforced concrete), pulp cement, wood chip cement, asbestos cement, calcium silicate, gypsum, There are non-ceramic ceramic materials such as gypsum slag, ceramic materials such as earthenware, pottery, porcelain, setware, glass, and enamel. The inorganic nonmetallic base material is mainly used as a plate or a three-dimensional object.
[0022]
In addition, examples of the substrate include a substrate obtained by laminating two or more of the above various materials by a known means such as an adhesive or heat fusion to form a composite. For example, resin-impregnated paper, FRP, and the like are also examples.
Also, once a decorative material is prepared as a decorative sheet using a sheet-shaped base material, and the decorative sheet is attached to another base material (sheet, plate, three-dimensional object) using an adhesive or the like as appropriate. The laminated material is also a decorative material of the present invention, and the base material of the decorative material is an example of a configuration in which two or more materials are laminated.
[0023]
Further, the other characteristics of the base material include, for example, the presence or absence of permeation of the liquid. For example, the substrate having no ink permeability is a resin sheet made of vinyl chloride resin, polyethylene terephthalate (PET), polyolefin resin or the like, and the substrate having the ink permeability is, for example, pure white paper for printing, reinforcement between papers. Paper, papers such as impregnated paper impregnated with a curable resin, and other fibrous base materials such as woven and nonwoven fabrics.
In the case of a substrate having ink permeability, when the permeability is impaired, it is preferable to form a known sealing resin layer (sealer layer) on the substrate in advance. An acrylic resin, a urethane resin, or the like is used for the filling resin layer. In addition, the filling function can also be used in a solid pattern layer described later.
[0024]
The thickness of the base material depends on the shape, material, application, etc., for example, when a fibrous base material such as paper is used, the basis weight is 50 to 150 g / m2.²The thickness is desirably about 50 to 300 μm.
[0025]
(Solid pattern layer and pattern layer)
The solid pattern layer 2 and the pattern layer 3 are not indispensable layers, but are layers provided as needed, but it is preferable to provide at least one of them in order to obtain a more decorative decorative material. However, it is usual to provide both of these in order to obtain a higher design. Further, the solid pattern layer is usually provided on the substrate side of the pattern layer. These layers may be provided after the matte resin layer and the gloss improving resin layer are formed, that is, may be provided so as to be the outermost surface layer. Is provided between the wear-resistant resin layer and the base material. Specifically, it is provided for the base material.
[0026]
As the solid pattern layer and the pattern layer, conventionally known ones may be appropriately used depending on the application. That is, the solid pattern layer 2 and the pattern layer 3 are formed by a conventionally known printing method such as gravure printing, screen printing, offset printing, gravure offset printing, ink jet printing, or the like using ink (or paint). Just do it. In the case of a solid pattern layer having a solid pattern on the entire surface, it may be formed by a known coating method such as roll coating or gravure coating.
[0027]
As the pattern pattern of the pattern layer, for example, wood grain pattern (conduit pattern, plate grain, straight grain pattern, etc.), stone pattern, sand grain pattern, satin pattern, cloth grain pattern, tile pattern, brick pattern, leather pattern, A character, a geometric pattern, a solid surface, a combination of two or more of these, or the like is used.
[0028]
In addition, as the ink (or coating liquid) used for forming the solid pattern layer or the pattern layer, a general vehicle including a binder, a coloring agent such as a pigment or a dye, and various additives appropriately added thereto are used. be able to. For example, as the binder resin, nitrocellulose, cellulose acetate, cellulose resin such as cellulose acetate propionate, acrylic resin, urethane resin, vinyl chloride-vinyl acetate copolymer, polyester resin, alkyd resin and other resins alone. Or mixed. As the coloring agent, for example, titanium white, zinc white, carbon black, iron black, red iron oxide, cadmium red, graphite, titanium yellow, cobalt blue, inorganic pigments such as ultramarine blue, aniline black, quinacridone red, polyazo red, Organic pigments such as isoindolinone yellow, benzidine yellow, phthalocyanine blue, and induslen blue, brilliant pigments such as flaky foil powder such as titanium dioxide-coated mica, shells, brass, and aluminum, and other dyes are used.
[0029]
In particular, in the case of a solid pattern layer, a colorant having a high concealment property such as titanium white, carbon black (black ink), or metal foil powder pigment is used to form a concealment layer for concealing the color tone of the substrate. Often.
[0030]
(Abrasion resistant resin layer)
The abrasion-resistant resin layer 4 is a resin layer containing an anti-abrasive a in order to improve abrasion resistance. The abrasion-resistant resin layer is a layer whose surface is rough and rough due to the lubricant contained therein. As the anti-abrasive a and the resin in which the anti-abrasive is dispersed and contained, conventionally known ones can be appropriately used depending on the application. The abrasion resistance obtained by the abrasion-resistant resin layer is not to a gloss mat design by an upper layer of the layer, but to a lower pattern layer, a solid pattern layer, a design by a layer such as a base material. On the other hand, if abrasion resistance to these is obtained, a minimum level of design expression of the decorative material can be secured and maintained.
[0031]
First, as the anti-wear agent a, a hard inorganic powder such as alumina, silicon carbide, or crystalline silica is preferable in terms of abrasion resistance performance. Needless to say, the hardness of the used anti-wear agent is higher than that of the resin which disperses and holds the anti-wear agent.
The size of the anti-wear agent is preferably about 5 to 50 μm in average particle size. If the particle size is too small, the abrasion resistance effect is reduced, while if the particle size is too large, the roughness of the surface of the wear-resistant resin layer increases, making it difficult to suppress the roughness by the smoothing resin layer. The average particle size is usually preferably about 0.3 to 2 times the thickness of the wear-resistant resin layer. If the magnification is less than 0.3, it is difficult to obtain sufficient wear resistance, and if it is more than 2, the filler may protrude too much on the surface of the wear-resistant resin layer and fall off the layer. Even if the average particle size is about the same as the thickness of the wear-resistant resin layer, usually, since the particles of the anti-wear agent have a particle size distribution, the maximum particle size is larger than the average particle size. To partially roughen the surface of the layer.
[0032]
The particle shape of the anti-wear agent is basically not particularly limited, and is, for example, a sphere, a polyhedron, an irregular shape, a scale, and the like. Specifically, spherical α-alumina or the like is used. In particular, a spherical shape (including an elliptical sphere and the like) is preferable in terms of wear resistance and scratch resistance.
The content of the anti-wear agent is usually about 2 to 30 parts by mass per 100 parts by mass of the resin component. If the content is too small, the effect of improving the wear resistance of the anti-wear agent cannot be sufficiently obtained, and if the content is too high, the function of the resin component to disperse and hold the anti-wear agent as a resin binder decreases, The flexibility of the wear-resistant resin layer is likely to be reduced.
[0033]
Next, as the resin used for the abrasion-resistant resin layer, a thermoplastic resin may be used, but a curable resin is preferable in terms of firmly dispersing and holding the anti-wear agent, and having a strong film strength and abrasion resistance of the resin itself. . As the curable resin, a thermosetting resin, an ionizing radiation curable resin, and the like are representative.
[0034]
As a typical example of the thermosetting resin, a two-component curable resin such as a two-component curable urethane resin can be used. As the two-component curable urethane resin, a polyol such as an acrylic polyol, a polyester polyol, or a polyether polyol is used as a main component, and 2,4-tolylene diisocyanate, 1,6-hexamethylene diisocyanate, or isophorone is used as a crosslinking agent (curing agent). Any known urethane resin using a polyisocyanate such as diisocyanate or a multimer or adduct thereof may be appropriately selected. Incidentally, as the polyisocyanate, it is preferable to use an aliphatic (or alicyclic) isocyanate (for example, hexamethylene diisocyanate, isophorone diisocyanate, etc.) in terms of weather resistance and heat-resistant yellowing.
In addition, examples of the thermosetting resin include a melamine resin, an alkyd resin, an epoxy resin, and an unsaturated polyester resin.
[0035]
Further, as the ionizing radiation-curable resin, specifically, a prepolymer (including a so-called oligomer) and / or a monomer having a radical polymerizable unsaturated bond or a cationic polymerizable functional group in a molecule is appropriately mixed. Preferably, a composition curable by ionizing radiation is used. Here, the term “ionizing radiation” means an electromagnetic wave or a charged particle having energy capable of causing a cross-linking and curing reaction of a molecule, and usually ultraviolet (UV) or electron beam (EB) is used.
[0036]
The above-mentioned prepolymer or monomer is, specifically, a compound having a radical polymerizable unsaturated group such as a (meth) acryloyl group, a (meth) acryloyloxy group, or a cationic polymerizable functional group such as an epoxy group in a molecule. Become. These prepolymers and monomers are used alone or as a mixture of two or more. Here, for example, the (meth) acryloyl group means an acryloyl group or a methacryloyl group. Further, as the ionizing radiation-curable resin, a polyene / thiol prepolymer obtained by combining a polyene and a polythiol is also preferably used.
[0037]
Examples of the prepolymer having a radical polymerizable unsaturated group in the molecule include polyester (meth) acrylate, urethane (meth) acrylate, epoxy (meth) acrylate, melamine (meth) acrylate, triazine (meth) acrylate, silicone ( (Meth) acrylate and the like can be used. A molecular weight of about 250 to 100,000 is usually used.
[0038]
Examples of the monomer having a radical polymerizable unsaturated group in the molecule include monofunctional monomers such as methyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, and phenoxyethyl (meth) acrylate. Examples of the polyfunctional monomer include, for example, diethylene glycol di (meth) acrylate, propylene glycol di (meth) acrylate, hexanediol (meth) acrylate, trimethylpropane tri (meth) acrylate, and trimethylolpropane ethylene oxide tri (meth) acrylate. Pentaerythritol tetra (meth) acrylate, dipentaerythritol tetra (meth) acrylate, dipentaerythritol penta (meth) acrylate, dipentaerythritol hexa (meth) acrylate and the like.
[0039]
Examples of prepolymers having a cationically polymerizable functional group in the molecule include prepolymers of epoxy resins such as bisphenol epoxy resins and novolak epoxy compounds, and vinyl ether resins such as fatty acid vinyl ethers and aromatic vinyl ethers. .
Examples of the thiol include polythiols such as trimethylolpropane trithioglycolate and pentaerythritol tetrathioglycolate. Examples of the polyene include those obtained by adding allyl alcohol to both ends of a polyurethane made of a diol and a diisocyanate.
[0040]
When crosslinking and curing with ultraviolet light or visible light, a photopolymerization initiator is added to the ionizing radiation-curable resin. In the case of a resin having a radical polymerizable unsaturated group, acetophenones, benzophenones, thioxanthones, benzoin, benzoin methyl ethers can be used alone or in combination as a photopolymerization initiator. In the case of a resin having a cationically polymerizable functional group, an aromatic diazonium salt, an aromatic sulfonium salt, an aromatic iodonium salt, a metallocene compound, a benzoin sulfonic acid ester, or the like is used alone or as a mixture as a photopolymerization initiator. be able to.
The addition amount of these photopolymerization initiators is about 0.1 to 10 parts by mass with respect to 100 parts by mass of the ionizing radiation-curable resin.
[0041]
In addition, the ionizing radiation-curable resin may be further mixed with a thermoplastic resin such as a vinyl chloride-vinyl acetate copolymer, a vinyl acetate resin, an acrylic resin, or a cellulose resin, as necessary, for adjusting physical properties. You may.
[0042]
As a source of ionizing radiation, a light source such as an ultra-high pressure mercury lamp, a high pressure mercury lamp, a low pressure mercury lamp, a carbon arc lamp, a black light type fluorescent lamp, and a metal halide lamp is used as an ultraviolet light source. As a wavelength of the ultraviolet light, a wavelength range of 190 to 380 nm is usually mainly used.
Further, as the electron beam source, various electron beam accelerators such as a Cockcroft-Walton type, a Van degraft type, a resonance transformer type, an insulating core transformer type, or a linear type, a dynamitron type, a high frequency type, and the like are used. Preferably, one that irradiates electrons having an energy of 100 to 300 keV is used. The irradiation dose of the electron beam is usually about 20 to 150 kGy.
[0043]
The wear-resistant resin layer can be formed by a known coating film forming method using a coating solution (or ink, the same applies hereinafter) comprising the above-described anti-wear agent and resin. For example, coating is performed by a conventionally known coating method such as roll coating. If the resin is an ionizing radiation-curable resin, use a non-cured room temperature solid (non-adhesive) in the uncured state after coating. You can also. The thickness of the wear-resistant resin layer is not particularly limited as long as it is appropriately determined according to required physical properties such as wear resistance, and is, for example, about 5 to 50 μm.
[0044]
In the coating liquid (or ink), conventionally known additives such as a dispersion stabilizer, an anti-settling agent, a colorant, and the like may be further added as needed for adjusting physical properties and the like. .
In addition, when there is a pattern layer or a solid pattern layer thereunder, the wear-resistant resin layer is usually transparent (including semi-transparent and colored transparent) so that it can be seen through.
[0045]
(Smoothing resin layer)
The smoothing resin layer 5 is a layer provided to fill the surface roughness of the lower wear-resistant resin layer 4 due to the inclusion of the anti-wear agent to make the surface as smooth as possible. Therefore, the surface of the smoothing resin layer may be a completely smooth surface (mirror surface). Good if less. Further, in practice, even if the surface is not mirror-finished, a sufficient effect can be obtained as long as some irregularities remain.
[0046]
By providing such a smoothing resin layer, the roughness of the rough surface of the wear-resistant resin layer is suppressed, and the ink transfer property when partially forming the gloss-improving resin layer on the matte resin layer surface is formed. Is good, and the contour of the gloss improving resin layer can be sharpened. In addition, the degree of matting of the matte resin layer is not affected by the roughness of the wear-resistant resin layer, and is easily adjusted. For this reason, the gloss mat design has a sharp outline, and the degree of matting and the degree of gloss improvement (by the gloss improving resin layer) can be easily adjusted, so that the design of the gloss mat can be improved.
[0047]
The matting resin layer and the wear-resistant resin layer, which are the upper and lower layers of the smoothing resin layer, both have irregular surfaces. Therefore, it is considered that a matte resin layer should be provided directly on the wear-resistant resin layer without providing the smoothing resin layer, but it is common. In addition, it is necessary to provide a layer to make the surface unevenness due to the wear-resistant resin layer once smooth, and then to provide a matte resin layer with the surface unevenness again. It is usually considered meaningless to do so. However, in practice, it has been found that by providing this smoothing resin layer, the surface unevenness of the matte resin layer can be made perfect as a matte surface in design. In addition, even if the thickness of the matte resin layer is increased without providing the smoothing resin layer, the matte degree of the matte resin layer is hardly stabilized due to the influence of the surface roughness of the wear-resistant resin layer, Difficult to adjust to any matte degree.
[0048]
As the resin of the smoothing resin layer, a resin as described above for the abrasion-resistant resin can be used. That is, a thermosetting resin represented by a two-component curable urethane resin or a curable resin such as an ionizing radiation-curable resin is preferably used.
For example, as the two-component curable urethane resin, a polyol such as an acrylic polyol, a polyester polyol, or a polyether polyol is used as a main component, and 2,4-tolylene diisocyanate or 1,6-hexamethylene diisocyanate is used as a crosslinking agent (curing agent). , Isophorone diisocyanate, or a known urethane resin using a polyisocyanate such as a polymer or adduct thereof. In addition, as a polyisocyanate, it is preferable to use an aliphatic (or alicyclic) isocyanate (for example, hexamethylene diisocyanate, isophorone diisocyanate, etc.) in terms of weather resistance and heat-resistant yellowing.
[0049]
When the wear-resistant resin layer is permeable, an extender pigment is preferably added to the smoothing resin layer in order to improve the sealing function of the smoothing resin layer. As the extender, known inorganic pigments such as silica, barium sulfate, and aluminum hydroxide can be used. The extender pigment may be added in an appropriate amount, and is usually 1 to 20 parts by mass with respect to 100 parts by mass of the resin component. The average particle size of the extender used is usually about 0.1 to 1 μm.
[0050]
Note that the smoothing resin layer may be formed by a conventionally known film forming method such as a coating method such as roll coating or a printing method such as gravure printing or screen printing. Further, the thickness of the smoothing resin layer may be a thickness capable of improving the smoothness of the rough surface of the wear-resistant resin layer, and is usually about 1 to 10 μm, more preferably about 3 to 7 μm. If the thickness is too small, a sufficient smoothing effect cannot be obtained. Conversely, if the thickness is too large, the effect is only saturated.
In addition, when the smoothing resin layer has a pattern layer or a solid pattern layer on the lower side, similarly to the wear-resistant resin layer, it is usually transparent (including translucent and colored transparent) so that it can be seen through.
[0051]
(Matte resin layer)
The matting resin layer 6 is a resin layer that expresses surface matting by containing a matting agent. As the matting agent, a conventionally known matting agent represented by silica or the like may be appropriately used. The silica used as a matting agent is usually finely divided silica having a particle size on the order of several tens of nanometers. As the matting agent, inorganic particles such as magnesium carbonate, resin particles such as resin beads, and the like are also used.
The content of the matting agent is usually about 1 to 20 parts by mass with respect to 100 parts by mass of the resin component. If the content is too small, the matting effect cannot be sufficiently obtained, and if the content is too large, film forming aptitude such as coating aptitude deteriorates.
As the resin used for the matte resin layer, the above-mentioned abrasion-resistant resin and the resin as described for the smoothing resin layer can be used. That is, a thermosetting resin represented by a two-component curable urethane resin or a curable resin such as an ionizing radiation-curable resin can be used. Therefore, further description is omitted here.
[0052]
The matte resin layer may be formed by a conventionally known film forming method such as a coating method such as roll coating or a printing method such as gravure printing or screen printing. Further, the thickness of the matte resin layer only needs to be thick enough to express the matte feeling of the surface, and is usually about 5 to 20 μm.
When the matte resin layer has a pattern layer or a solid pattern layer on the lower side, similarly to the wear-resistant resin layer, the matte resin layer is usually transparent (including semi-transparent and colored transparent) so that it can be seen through.
[0053]
(Gloss improving resin layer)
The gloss improving resin layer 7 is a layer whose gloss is relatively larger than that of the matte resin layer. Therefore, the gloss of the gloss-improving resin layer may be the full gloss of the uppermost gloss, or may be a gloss (including a mat) having a lower gloss than the total gloss. For example, the matte resin layer and the matte improving resin layer are both matte, but the matte improving resin layer also includes a combination having a lower matte degree. Similarly, the matting degree of the matte resin layer described above does not need to be perfect matting, and may be a matte that is smaller than the matte provided by the matte improving resin layer. That is, it is sufficient that the gloss of the matte resin layer and the gloss of the gloss improving resin layer have a relative magnitude relationship. By providing such a gloss-enhancing resin layer partially on the matting resin layer in a pattern, the pattern of most of the gloss by the gloss-enhancing resin layer and the part exposed under the non-formed part of the gloss-enhancing resin layer The gloss matte design, which is a gloss change pattern, is expressed by the pattern of the small gloss (matte) portion by the matte resin layer.
[0054]
As the resin of the gloss improving resin layer, similarly to the matte resin layer, a resin as described in the above-mentioned abrasion resistant resin, smoothing resin layer and the like can be used. That is, a thermosetting resin represented by a two-component curable urethane resin or a curable resin such as an ionizing radiation-curable resin can be used. Therefore, further description is omitted here.
In order to adjust the degree of gloss, the gloss improving resin layer may contain a matting agent within a range not lower than the matting resin layer. As the matting agent, those described above for the matting resin layer can be used. Further, a lubricating agent such as silicone or wax may be added to the luster improving resin layer because the luster improving resin layer becomes the outermost surface layer. In addition, conventionally known additives such as a colorant and a light stabilizer can be appropriately added as needed.
[0055]
In addition, the resin of each layer of the wear-resistant resin layer, the smoothing resin layer, the matte resin layer, and the gloss-improving resin layer is preferably the same resin between adjacent resin layers, which is preferable in terms of interlayer adhesion. It is. For example, all four layers may be formed of the same urethane resin or may be formed of an ionizing radiation curable resin. Alternatively, among these, for example, three layers except the smoothing resin layer are made of the same resin. These may be appropriately determined according to required physical properties and the like.
[0056]
The gloss-enhancing resin layer may be formed by a method capable of forming a desired pattern, for example, by a known printing method such as gravure printing or screen printing. In addition, the thickness of the gloss improving resin layer is usually about 5 to 20 μm.
[0057]
By the way, the gloss mat design by the matte resin layer and the gloss improving resin layer, the surface gloss change pattern, by synchronizing the position of the pattern of the pattern layer provided between the substrate and the wear-resistant resin layer, Higher design expressions are possible. For example, a wood grain conduit pattern, a stone grain pattern, and the like. Also, by making the portion to be expressed as a concave portion a comparatively small gloss portion, that is, an exposed portion of the matte resin layer, a pseudo (more than a slight unevenness due to the thickness of the gloss enhancing resin layer but more than the actual concave portion). A three-dimensional effect can also be expressed. Such a pseudo three-dimensional design expression is, for example, a wood grain pipe pattern, a stone grain pattern, or the like.
Note that the position tuning includes a form in which the pattern portion of the pattern layer and a portion in which the gloss improving resin layer is formed coincide with a form in which a portion in which the gloss improving resin layer is not formed coincides.
[0058]

[Comparative Example 4]
As a decorative material 20 as illustrated in the cross-sectional view of FIG. 4, a decorative sheet expressing a pseudo three-dimensional effect of a wood grain conduit pattern was manufactured as follows.
Specifically, the solid pattern layer 22, the pattern layer 23, and the abrasion resistance were formed on the substrate 21 in the same manner as in Example 1 except that the formation of the smoothing resin layer 5 was omitted in Example 3. The desired resin material was obtained by laminating the conductive resin layer 26, the matte resin layer 25, and the gloss-improving resin layer 28 in the same manner with the same material as in Example 3.
[0091]
(Performance evaluation)
With respect to the decorative material (decorative sheet) produced in each of Examples and Comparative Examples, the design properties (gloss mat feeling, sharpness of the contour of the gloss mat pattern, depth of painting feeling) and abrasion resistance were evaluated. The design feeling was evaluated by visual observation.
The abrasion resistance was measured by using a Taber abrasion tester according to JIS K6902 for a decorative sheet obtained by attaching a decorative sheet to an MDF (medium fiber slab) with an adhesive. Under the conditions of −42 and a load of 9.81 N (1000 gf), evaluation was performed by the number of times (the number of middle points) until half of the pattern of the pattern layer was removed. The results are summarized in Table 1.
[0092]
The symbols in the table indicate that は is excellent, は is good, Δ is slightly good, and × is bad.
In the gloss matte feeling, when the gloss difference between the gloss part (large gloss part) and the mat part (small gloss part) is 50 or more, measured at 75 degrees by a gloss meter, 、, those having a gloss difference but not more than 30 were rated as △, and those having no gloss matt were rated as ×.
Also, in the sharpness, ◎ is for those that faithfully represent even fine conduits, ○ is for those that represent incomplete but fine conduits, and Δ is for those that do not adequately represent fine conduits. Is not represented as x.
In addition, in the depth, those in which the feeling of painting was thick were evaluated as ○, those in which there was a feeling of painting but the thickness was not felt were rated as Δ, and those in which the feeling of painting itself was not felt were rated as ×.
The abrasion resistance is good if it is 300 times or more, and excellent if it is 500 times or more.
[0093]
[Table 1]

[0094]
As a result, as shown in Table 1, in the examples, the sharpness and the depth of the painted feeling were generally improved, and the gloss matte feeling was good. Also, of course, there was no roughness on the surface of the decorative material and the scratch resistance was good. Specifically, in Example 1, the roughness of the surface of the abrasion-resistant resin layer was reduced by the smoothing resin layer, the transferability of the coating liquid / ink of the matte resin layer and the gloss-enhancing resin layer was improved, and the sharpness was improved. Tune effect was obtained.
In addition, in Example 2, the surface of the matte resin layer (matte but less affected by roughness of the lower wear-resistant resin layer was further reduced by adding an extender having an effect of filling to the smoothing resin layer. T) It became smooth, and the film thickness could be relatively increased, and the painting feeling and the depth were increased.
[0095]
Further, in Example 3, the matte resin was changed from a two-component curable urethane resin to an electron beam curable ionizing radiation curable resin for the wear-resistant resin layer, matte resin layer, and gloss improving resin layer. The matting agent (silica) added to the resin layer did not lift up to the surface, and the matte resin layer became glossy, and the gloss matte feeling was lower than in Example 2, but the abrasion resistance was improved.
In Example 4 using the same ionizing radiation-curable resin, the two-part curable urethane resin was used because the average particle size of the matting agent (silica) added to the matting resin layer was increased to 5 μm. The gloss mat effect equivalent to that of Example 2 was maintained, and the wear resistance was also improved.
Further, in Example 5, in which the resin of the smoothing resin layer was changed from a two-component curable urethane resin to an electron beam-curable ionizing radiation curable resin, the abrasion resistance was further improved.
[0096]
On the other hand, in Comparative Example 1 in which the abrasion-resistant resin layer was provided as the outermost surface layer, a sharp tuning effect could not be obtained because the surface of the decorative material had roughness and the amount of application was large.
In Comparative Example 2 in which the application amount of the wear-resistant resin layer was reduced, the tuning effect was improved, but the wear resistance was reduced.
Further, in Comparative Example 3 in which a wear-resistant matting resin layer containing the same layer of a wear-resistant agent and a matting agent was provided and a gloss-improving resin layer was provided thereon, the surface of the wear-resistant matting resin layer was The transfer agent of the ink at the time of forming the gloss improving resin layer was poor and lacked sharpness, and a sufficient design effect could not be obtained.
In Comparative Example 4 in which the smoothing resin layer was omitted (compared to Example 1), the sharpness was improved as compared with Comparative Example 3, but there was no deep coating feeling, and the design was still insufficient. Was.
[0097]
