Some are attached to a substrate, for example, (1)
A method of forming irregularities on a substrate sheet on which a pattern is applied by using an embossing roll, an embossing template, or the like; (2) Visually applying a matte conduit print or the like on the substrate sheet in a decorative manner. (3) forming a printed portion such as a conduit for forming a concave surface on a substrate sheet on which a pattern is formed with an ink containing a lyophobic agent,
A method of forming a concave portion by applying a transparent resin thereon and making the printed portion of the conduit or the like liquid-repellent, or (4) forming a printed portion of the conduit or the like with foaming ink, polishing by heating and foaming. Although a method of forming a concave portion is known, all of these methods apply an uneven pattern to the surface of a base sheet made of a synthetic resin sheet such as paper, vinyl chloride, and acrylic, and adhere it to a substrate. As a result, it is produced as a decorative material having a design with a concavo-convex pattern on the surface, and there is a problem that water resistance, weather resistance, heat resistance, and the like are poor.

Also, without using the above-described base sheet, a pattern such as a grain or a conduit is directly printed on the substrate by the same method as in the above (2), or the grain or the pipe is printed by a normal pattern printing. A method of forming a concave portion by the method (3) or (4) on a surface expressing a conduit or the like, or a method of forming a concave portion on a transfer sheet substrate by forming a printed portion such as a conduit with an ink containing a liquid repellent agent. Furthermore, a method of transferring the image onto a substrate using a transfer sheet provided with a pattern and then applying a transparent resin thereon can be considered. However, in the case of direct printing, the smoothness and printability of the substrate itself are based on the above-mentioned basic methods. Since the material sheet is generally inferior, the design of the pattern is not good, and the production efficiency at the time of printing the pattern is very poor. Because a pattern layer is provided on the upper surface, a delicate pattern cannot be formed. Adhesion of the picture pattern was there was a problem that it is inferior.

FIG. 1 is a cross-sectional view showing an embodiment of a decorative plate for forming a concavo-convex pattern of the present invention, FIG. 2 is a cross-sectional view showing another embodiment of a decorative plate for forming a concavo-convex pattern of the present invention, and FIG. FIG. 2 is a cross-sectional view for explaining an example of a method for manufacturing a plate, wherein 1 and 1 ′ are decorative plates forming a concavo-convex pattern, 2 is a base material, 3 is an adhesive layer, 4 is a liquid repellent agent layer, 5 is a picture layer, and 6 is a transfer. A picture layer, 7 is a transfer sheet substrate, 8 is a transfer sheet, and 9 is an uneven pattern layer.

As shown in an embodiment of FIG. 1, the basic structure of the decorative plate 1 having a concavo-convex pattern according to the present invention comprises a liquid repellent agent layer 4 formed on the surface of a base material 2 by ink containing a microcapsule liquid repellent. A picture layer 5 formed of normal ink is provided, and a transparent resin is laminated on the liquid repellent layer 4 formed of ink containing the microcapsule liquid repellent and the picture layer 5 of normal ink. The configuration is such that the uneven pattern layer 9 is formed by being repelled by the layer 4, and the configuration does not include paper, film, and the like.

As shown in another embodiment of FIG. 2, when the ink forming the picture layer 5 has no or low adhesion to the base material 2, the base material 2 and the picture As an arrangement in which the adhesive layer 3 is provided between the adhesive layer 3 and the layer 5, the decorative pattern forming decorative board 1 ′ in which the picture layer 5 is transferred and formed on the surface of the base material 2 via the adhesive layer 3 may be used. As the adhesive layer 3, a two-component curable urethane-based resin, a polyamide-based resin, or the like is used.

Next, an example of a method for producing the decorative board 1 'with a concavo-convex pattern of the present invention will be described with reference to the drawings. First,
As shown in FIG. 3A, a transfer sheet 8 provided with a transfer picture layer 6 composed of a liquid repellent agent layer 4 made of ink containing a microcapsule liquid repellent and a picture layer 5 made of ordinary ink on the surface of a transfer sheet base 7. Prepare Next, as shown in FIG. 3B, an adhesive layer 3 was provided on the surface of the substrate 2. Next, FIG.
As shown in (c), the transfer pattern layer 6 of the transfer sheet 8 is overlapped so as to face the adhesive layer 3 provided on the surface of the substrate 2, and the transfer sheet 8 is heated and pressed from the surface of the transfer sheet 8.
Next, as shown in FIG. 3D, the transfer sheet base 7 of the transfer sheet 8 is peeled off, and the liquid repellent agent layer 4 and the picture layer 5 are provided on the surface of the base 2. Further, as shown in FIG. 3 (e), a transparent resin is applied to the upper surface of the liquid repellent agent layer 4 and the picture layer 5, and then cured to form the liquid repellent agent layer 4 and the uneven pattern layer 9 made of the transparent resin. Thus, a decorative plate 1 ′ having a concavo-convex pattern is obtained.

The base material 2 used for the decorative pattern-formed decorative board 1 of the present invention is wood, plywood, particle board, M
It is possible to use inorganic base materials such as wood base materials such as DF, calcium silicate plate, asbestos slate plate, lightweight foam concrete plate and gypsum board, and metal base materials such as polished steel plate, galvanized steel plate and aluminum plate. .

As shown in FIG. 3A, the transfer sheet 8 used for producing the decorative boards 1 and 1 'having a concavo-convex pattern includes a capsule liquid repellent on the upper surface of the transfer sheet substrate 7. A transfer picture layer 6 composed of a liquid repellent layer 4 made of ink and a picture layer 5 made of ordinary ink is laminated. As the transfer sheet substrate 7, it is preferable to use a material used as a normal transfer sheet substrate, such as a plastic film such as polyethylene terephthalate, polyethylene, polypropylene, nylon, and cellophane, or a composite film of these and paper. If necessary, a release layer may be formed on the surface of the transfer sheet substrate. In addition, in the transfer sheet 8 of FIG. 3A, the pattern layer 5 is the outermost layer.
May be added. The reason why the adhesive layer 3 is not required is that the picture layer 5 may be capable of imparting adhesiveness to itself, and the other reason is that the decorative board substrate 2 on the side to which the picture is transferred is used. This is because the adhesive layer 3 may be provided on the surface.

Next, the ink containing the microcapsule liquid repellent forming the liquid repellent layer 4 is formed by using a known thermoplastic resin, thermosetting resin, ionizing radiation curable resin, or the like as a vehicle, and adding the liquid repellent to the vehicle. If necessary, other additives, for example, a colorant such as a pigment or a dye, an extender pigment, a solvent, a stabilizer, a plasticizer, a curing agent, and the like can be appropriately mixed.

The liquid-repellent used in the liquid-repellent ink may be, for example, silicone, polyethylene wax, paraffin wax, amide wax, wax wax, or the like, in hollow particles of a thermoplastic resin or in hollow portions of hollow microballoons formed of inorganic walls. And a capsule-like liquid repellent in which a liquid repellent substance such as a vinyl fluoride compound is enclosed. For the resin forming the capsule, a vinylidene chloride-acrylonitrile copolymer or the like can be used, and for the hollow microballoon composed of an inorganic wall, a glass microballoon,
Examples include silica microballoons, hollow calcium carbonate capsules and calcium sulfate capsules obtained by an interfacial polymerization method. A liquid repellent is penetrated into the inside of the hollow micro balloon and coated with an organic polymer to prevent volatilization and leakage of the core material. It is released and exhibits liquid repellency. That is, since the liquid repellent containing microcapsules does not exhibit liquid repellency at the time of printing, the printability of the picture layer is good, a fine pattern is formed, and the adhesion between the liquid repellent layer and the picture layer is also good. The capsule preferably has a particle size of 5 to 20 μm. The addition amount is desirably 0.1 to 10% by weight. If necessary, a matting agent may be added. Examples of the matting agent include silica, calcium carbonate, acrylic beads, and melamine beads.

The pattern layer 5 made of ordinary ink is printed with, for example, wood grain, stone grain, surface pattern of natural leather, cloth grain, abstract pattern, etc., and is used as a vehicle of the ink for forming an arbitrary pattern. A general-purpose resin made of an acrylic resin, a urethane resin, a vinyl chloride resin, or the like is used. Further, the pattern layer 5 can be composed of a solid ink layer of solid printing and a pattern ink layer of wood grain, stone grain, etc., and the solid ink layer can contain a brilliant pigment together with a coloring pigment. The solid ink layer may be configured so as to contain only the coloring pigment and not to include the glittering pigment, and to be configured to include the glittering pigment in the picture ink layer. When a bright pigment is contained in the picture ink layer, a special visual effect and a three-dimensional effect can be created by changing the color tone of the bright pigment and relating them to each other's pattern.

FIG. 3E shows a state in which a transparent or translucent resin is applied on the liquid repellent agent layer 4 and the picture layer 5 transferred to the base material 2. This transparent resin is repelled and thinned in the lyophobic agent layer 4 containing the lyophobic agent.
Alternatively, the liquid repellent agent layer 4 is formed to be relatively thick in a place where the liquid repellent agent layer 4 is not formed, so that unevenness is formed as a whole. When the transparent resin is dried and cured in this state, the uneven pattern layer 9 is formed, and the uneven pattern-formed decorative board 1 ′ of the present invention is formed.
Can be produced. As the transparent resin forming the concavo-convex pattern layer 9, it is desirable to form a film having excellent surface properties such as contamination, solvent properties, and scratch resistance. As the resin system, an acrylic resin, a urethane resin, or the like is used. Thermosetting resins, ionizing radiation-curable resins such as polyester acrylate and urethane acrylate are preferably used. Known coating methods such as flow coating, gravure coating, roll coating, and spray coating can be used as the coating method.
The coating amount is preferably from 10 to ²⁰⁰ g / m ² .

A transfer sheet was prepared as a layer. [Ink composition containing microcapsule liquid repellent] Acrylic polyol resin 100 parts by weight Polyisocyanate curing agent 10 Microcapsule liquid repellent 3 Separately, a two-part curable urethane resin adhesive is applied on the surface of a 3 mm thick MDF plate at 100 g / m. Coating was performed with a ^two- roll coater to prepare a base material for decorative board. Then placed as transfer pattern layer surface of the transfer sheet to the adhesive layer surface of the veneer substrate opposite the transfer conditions Temperature 220 ° C., a pressure 3 kg / cm ²
At 15 m / min for transfer. The transfer sheet substrate of the transfer sheet was peeled off to complete the transfer of the picture. Subsequently, as a top coat layer on the entire surface of the pattern layer, a transparent two-part curable urethane-based paint is applied in an amount of 100 g.
/ M was applied using a curtain flow coater at ^2, dried and cured, thinned repelled transparent two-component curable urethane resin layer in grain conduit shank by ink containing a microcapsule liquid repellent agent, and The portion became matte to form a concave portion, and a wood grain decorative plate having a channel concave portion synchronized with the wood grain pattern was obtained.

[0018]

As described above, according to the present invention, since the liquid repellent agent layer and the picture layer are provided on the surface of the base material without using a printing sheet by transfer, a fine picture pattern can appear. By forming a transparent resin layer on the liquid repellent agent layer and the pattern layer, a decorative plate having a concave / convex pattern having a good concave / convex pattern layer synchronized with the pattern on the surface can be obtained.

Since the liquid repellent is formed on the surface of the transfer sheet substrate by ink containing the microcapsule liquid repellent and is provided on the substrate surface by heating and pressing, the adhesiveness to the picture layer and the printability with the ordinary ink are also good. Thus, it is possible to obtain an embossed pattern-formed decorative board having a good pattern and an embossed pattern having excellent adhesion and good design.

Further, since the picture layer is directly provided on the surface of the base material by transfer without using printing paper, the picture layer is excellent in water resistance and weather resistance, and there is no decrease in adhesion when used around water. It can be used as interior materials for kitchens, bathrooms, etc.
