摘要：
The present invention relates to a decorative paper with high abrasion resistance. The present invention provides a thin film containing a thermosetting resin hardener on a sheet of decorative paper. The decorative paper is then impregnated with thermosetting resin. In the press process to manufacture a decorative board, since the thermosetting resin around the printed layer hardens faster than the resin of the raw paper, the resin on the surface is not absorbed and forms a thick hardened film. This provides a decorative board of excellent surface properties including high abrasion resistance.
技术问题语段：
Although high quality products can be obtained from this manufacturing process, there are disadvantages.|Further, sanding of the adhesive surface is required, and numerous processes are involved.|However, it is easy to compromise the characteristics of the surface such as a decrease in luster in the process where water content starts evaporating as steam and escapes from the formed surface.|Otherwise it is difficult to control the luster and its consistency.|As a result, abrasion resistance of the decorative paper layer of the product tends to be insufficient.|However, the effect is not sufficient, and especially in the latter, heat stability decreases in the forming process and the properties of the surface of the product tend to be poor.
技术功效语段：
As stated above, in the impregnated paper of the present invention which uniformly contains thermosetting resin hardener in a surface layer of the decorative paper, thermosetting resin around the layer containing the hardener hardens more rapidly than the resin of other areas due to the effect of the hardener. The resin closer to the surface is prevented from shifting and gives a decorative board excellent surface properties by forming a film of thick hardened resin on the surface. At the same time, the resin layer which rapidly hardens due to the effect of the hardener is formed over the raw paper, and because the thermosetting resin in the paper which is required as an adhesive is not prevented from transferring to the base material from within the raw paper or the back side of the raw paper, adhesive strength between the decorative paper and the base material does not decrease as compared with when no hardener is contained.
权利要求：
I claim:
1. A decorative material comprising:
a sheet of substrate paper;
a layer of printing ink having a first side and a second side and containing thermosetting resin, the second side facing the sheet of substrate paper; and
a layer coating the first side of the layer of printing ink and having approximately 100 weight part varnish and approximately 6 weight part thermosetting resin hardener so that a value of at least 94% is obtained in a glossmeter measurement using a glossmeter of 60.degree. incidence and 60.degree. photometry when the laminated material is disposed in a base material.
2. A decorative material comprising:
a sheet of substrate paper;
a layer of printing ink for providing a print pattern; and
a layer having substantially 100 weight part varnish ink and substantially 6 weight part resin hardener disposed between the sheet of substrate paper and the layer of printing ink so that at least 50% of the print pattern remains in the decorative material after approximately 100 abrasions in JAS Taber's abrasion test performed on the laminated material coupled to a base material, wherein the layer of printing ink includes a thermosetting resin and a thermosetting resin hardener.
