DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the decorative sheet shown by 5452, since the colored ink containing a small amount of the liquid repellent is attached to the surface of the base material other than the concave portions (projections), the transparent or colored transparent coating layer and the base material The adhesive strength is insufficient, and in the case of a coating layer made of an ionizing radiation curable resin, there is a drawback that it may be partially peeled off after long-term use. In addition, in the conventional decorative sheet disclosed in Japanese Patent Laid-Open No. 4-305452,
Colored ink containing a small amount of liquid repellent is attached to areas other than depressions (projections) on the surface of the base material, so it should be transparent or colored in areas where it should not be repelled (projections). There is a drawback that the paint layer itself is partially repelled.

The present invention has been conceived in order to solve the above-mentioned drawbacks of the prior art, and it is applied to various furnitures, building interior materials, etc. for the purpose of decoration or surface protection. The present invention relates to a decorative sheet having a strong surface, particularly suitable for expressing uneven patterns such as wood grain and a surface having a strong decorative sheet, and a method for producing the same, in which the surface paint layer does not peel off. A high decorative sheet and a method for producing the same are provided.

The invention of a method for producing a decorative sheet is as follows: After filling a concave portion of a base material having a concave portion with a liquid-repellent resin, a primer and a transparent or colored transparent paint are sequentially coated on the surface of the base material. Then, the primer and the paint adhered to the surface of the liquid-repellent resin layer are repelled by the liquid-repellent performance of the liquid-repellent resin layer filled in the recess, and then the primer and the paint are solidified.

While laminating by thermal bonding, may be a laminated sheet by so-called doubling emboss obtained by performing shaping by embossing on the surface of the laminated plastic film, but in particular,
Using a laminated sheet obtained by doubling and embossing another polyvinyl chloride film on a polyvinyl chloride sheet with a printed surface makes it possible to create a feeling of depth and flesh. It is most preferable in that a good decorative sheet can be obtained and excellent design characteristics can be obtained. Incidentally, in the embossing step of shaping the concave portion on the surface of the base material, following the pressing step with the embossing plate having the convex portion, a flattening treatment for crushing the burr on the edge of the concave portion formed by the embossing plate is performed. For example, it is preferable to perform the pressing by a mirror surface or a matte surface.

To form the liquid-repellent resin layer filled in the recesses on the surface of the substrate of the present invention, an ink or paint containing a liquid-repellent substance is wiped onto the surface of the substrate. The method applied by the valley print method is used.

The liquid-repellent resin layer filled in the concave portion is a coating material for forming a transparent or colored transparent coating material layer formed so as to cover the surface of the base material other than the concave portion. However, when the width of the resin layer is less than 200 μm, the liquid repellency becomes insufficient, and when it exceeds 700 μm, it is used for forming a transparent or colored transparent coating layer. Tumbling occurs due to unpainted residue of the paint. Therefore, the recess of the base material has a surface width of the liquid-repellent resin layer filled in the recess of 200 to 700 μm.
m, preferably 300 to 500 μm.

Of a coating material having a resin-forming property or a thermoplastic resin as a film-forming component, for example, roll coating, curtain flow coating, wire bar coating, reverse coating,
It is formed by coating and solidifying with gravure coat, gravure reverse coat, air knife coat, kiss coat, blade coat, smooth coat, comma coat and the like.

The transparent or colored transparent coating layer forming the top coat layer is as thick as possible since the thickness of the coating layer leads to improvement of sharpness of the recesses formed on the surface of the decorative sheet.

The obtained decorative sheet was a decorative sheet with an unnatural design because the transparent paint layer was repelled even in the areas other than the concave sections (projections) having a shape corresponding to the conduit pattern on the surface of the oak plate. Furthermore, the adhesion between the transparent paint layer and the transparent polyvinyl chloride film was insufficient because there was no primer layer in between, and it was easily peeled off with a cellophane tape or the like.
