DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative paper which is laminated on a base material and is used for a storage member or furniture. Tuned three-dimensional decorative paper.

[0002]

2. Description of the Related Art Conventionally, after a pattern layer having a liquid repellent action is printed, a top coat paint is applied on the pattern layer, and the top coat paint is flicked only on the surface of the pattern layer and cured. 2. Description of the Related Art A decorative paper having an uneven pattern formed on its surface is known.

[0003] As shown in Fig. 3, a paper base material impregnated with a resin or mixed with a resin is repelled by a matting agent (eg, silica, calcium carbonate, etc.) and a silicone resin as shown in Fig. 3. The pattern layer which becomes the concave part of the concavo-convex pattern is provided with the thermosetting resin ink to which the liquid agent is added and mixed, and a curable top coat paint such as urethane is applied over the entire surface from above, and only the surface of the concave pattern layer is repelled. Japanese Unexamined Patent Publication No. Sho 61-29110 discloses a decorative paper having a concave-convex pattern in which a concave portion is formed and a convex portion of a top coat paint is formed in another portion.

[0004]

However, on the concave pattern layer (13) made of a thermosetting resin ink in which a matting agent and a liquid repellent agent are added and mixed, the remnant (1) of the top coat paint (12) is formed.
2a) (Top coat paint is likely to remain in a granular form on the concave pattern layer) easily occurs, and when sticking a turn roll of an applicator or this decorative paper to a base material, it has been a problem that it adheres to a laminate roll. . This is because the thermosetting resin ink that forms the concave pattern layer (13) mixes silica gel powder as a matting agent, but is buried in the ink because of the powder, and the top coat paint with silica gel powder is used. The absorbency of the paint becomes weaker, and the remnants (12a) of the paint become large particles and are deposited on the concave pattern layer. Therefore, the surface of the concave pattern layer did not become matte (low gloss) but became a gloss (high gloss) surface.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to eliminate the remnants of top coat paint remaining on a concave pattern layer having a liquid repellent action, and the paper interval has been strengthened by resin impregnation or resin mixing. On the paper substrate (10), a concave pattern layer (13) is formed with a curable ink containing a liquid repellent, a top coat paint (12) is applied on the concave pattern layer, and the surface of the concave pattern layer is coated. In a tuned three-dimensional decorative paper having an uneven pattern formed on its surface by popping a top coat paint, the curable ink containing a liquid repellent agent has a porous silica having an average particle size of 0.2 to 1.2 μm.
(K) is kneaded to form a porous three-dimensional decorative paper having the concave pattern layer formed thereon.

The present invention will be described in detail. Examples of the resin to be impregnated in the base paper include a urea resin, a melamine resin, and an acrylic resin, and a mixed paper obtained by mixing these resins at the time of papermaking may be used.

After the grain pattern printing (11) is appropriately performed on the base paper, the conduit portion of the grain pattern is printed as a concave pattern layer (13). The ink for forming the concave pattern layer is prepared by adding 2 to 5% of a silicone resin or a fluororesin as a liquid repellent to a thermosetting vehicle such as an acrylic urethane, urethane, or melamine resin to form a matting agent ( 5 to 10 parts of silica), and 1 to 4% of porous silica (K) having an average particle size of 0.2 to 1.2 μm, and a concave pattern layer made of a thermosetting resin ink colored with a coloring pigment. To form

After forming the concave pattern layer, a top coat paint (12) of a curable resin such as urethane, acrylic urethane, acrylic or melamine is applied to the entire surface from above, and the surface of the concave pattern layer (13) is coated. A concave part (conduit part) is formed by repelling only the paint, and a convex part is formed by the top coat paint (12) except for the concave part pattern layer. Obtainable.

[0009]

According to the present invention, there is provided a thermosetting resin ink for forming a concave pattern layer, wherein porous silica (having a particle size of 0.2 to 1.2) is used.
μm), the porous silica absorbs the repelling residue (12a) of the top coat paint (12), and fixes the paint to form a granular repellent on the surface of the concave pattern layer (13). The rest does not occur. As a result, the concave pattern layer surface becomes a beautiful matte surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described. FIG. 1 is an explanatory view showing an example of a laminated structure of a tuned three-dimensional decorative paper according to the embodiment of the present invention. FIG. 2 is an enlarged photograph (A) showing the surface portion of the tuned three-dimensional decorative paper according to the embodiment of the present invention, and an explanatory diagram (B) thereof. Further, FIG. 3 is an enlarged photograph (A) showing a surface portion of a tuned three-dimensional decorative paper by a conventional manufacturing method and an explanatory diagram (B) thereof.

A specific embodiment will be described based on the configuration shown in FIG.

Example 1 An acrylic resin was adsorbed on pulp fibers, and a 30 g / m ² thin paper made of paper (resin 50%) was printed with a wood grain pattern by an ordinary gravure printing method.
Thereafter, a concave pattern layer (conduit pattern section) for forming a concave is printed by a gravure printing method using the following thermosetting resin ink. Next, 7 g / m ² (dry) of a urethane resin was applied to the thin paper on which the wood pattern was printed by a gravure printing machine and dried to obtain a tuned three-dimensional decorative paper having a realistic feeling similar to natural wood. The composition of the thermosetting resin ink (for the concave pattern layer) is as follows. Polyol 20 parts Matting agent (silica) 10 parts Silica gel 2 parts (particle size 0.2-1.2 μm) Solvent 60 parts (toluene, ethyl acetate, etc.) Isocyanate 20 parts Silicone 1 part Color pigment a little

<Comparative Example 1> As a comparative example, a tuned solid printed with a thermosetting resin ink containing no porous silica under the same conditions as in Example 1 except for the thin paper (resin papermaking), the ink vehicle, and the amount of silicone added. A decorative paper was prepared and compared with the examples.

[0014]

[Table 1]

[0015]

According to the present invention, a thermosetting ink for a concave pattern layer forming a conduit pattern is added to a conventional matting agent in an amount of 0.2 to 0.2%.
By kneading the 1.2 μm porous silica, the remnants of the top coat paint on the concave pattern layer can be absorbed into the silica and the remaining remnants can be fixed, so that the particulate remnants are eliminated. Can be. Therefore, even if a large amount of decorative paper is printed, it is possible to prevent paint from adhering to the turn roll and the laminate roll. In addition, the porous silica makes it possible to obtain a mat surface with a beautiful concave pattern layer surface and to obtain a tuned three-dimensional decorative paper having a sharp uneven pattern. Furthermore, since no granular remnants remain as a secondary curing, even after a large number of laminated decorative papers of the present invention are laminated on a base material (particle board, MDF, etc.), the collapse of the load due to slippage is eliminated. Produces various excellent effects.
