上の欠点が目立ち、特に、ベタ調やメタリック調の外観
を有した欠点のない熱硬化性樹脂化粧板を得ることは難
しかった。However, since the impregnated paper used here is porous, which is easily impregnated, minute ink dropouts occur when printing the desired pattern with ink, and this also occurs when printing patterns. , the defects are very noticeable in solid printing. For this reason, the obtained thermosetting resin decorative board has noticeable defects in appearance, and it has been particularly difficult to obtain a thermosetting resin decorative board without defects having a solid or metallic appearance.

板表面がインキ層となる為、物理化学的性質が劣る。In order to solve the above drawbacks, there is a method of stacking a transfer film on impregnated paper so that the ink layer is in contact with the impregnated paper, hot-pressing molding, and peeling off the release paper of the transfer film, but the surface of the decorative board is not the same as the ink layer. Therefore, the physicochemical properties are inferior.
本発明の目的は、上記従来技術の欠点ないし問題点を解
消し、表面物性、意匠性いずれにも優れた熱硬化性樹脂
化粧板が得られる製造法を提供することにある。An object of the present invention is to provide a manufacturing method that eliminates the drawbacks and problems of the above-mentioned conventional techniques and provides a thermosetting resin decorative board with excellent surface properties and design properties.

った。The object of the present invention is to directly form an ink layer on resin-impregnated paper constituting a thermosetting resin decorative board. It has been found that this can be achieved by polymerizing the film on which the ink layer has been formed onto the resin-impregnated paper and integrating it under heat and pressure.

If you use a film such as polyvinyl alcohol film, cellophane, etc. that has hydroxyl groups in its molecular structure and undergoes a condensation reaction when curing melamine resin or benzoguanamine resin, resulting in an adhesive bond, the resin-impregnated paper and printing layer can be bonded together. This is preferable because it has good adhesion to the coated film. Also, when the thermosetting resin-impregnated paper is diallyl phthalate resin or unsaturated polyester resin-impregnated paper, the polymerization side of the film to the thermosetting resin-impregnated paper should be pre-treated. , be subjected to adhesive treatment such as corona treatment, plasma treatment, radiation treatment, flame treatment, etc., or coated with hot melt adhesive such as acrylic, vinyl chloride, alkyd, or ethylene vinyl acetate. The thickness of the above-mentioned film is preferably thinner from an economic point of view, but it is necessary to have printability. Therefore, 12 to 50μ is preferable.

た化粧板を製造しうる。The thermosetting resin-impregnated decorative board obtained by the method of the present invention has physicochemical properties such as surface abrasion resistance, solvent resistance, chemical resistance, and kill resistance that are superior to general high-pressure laminated decorative boards using overlay paper. It is equivalent to a board. In addition, since the surface of impregnated paper cannot be made smoother to maintain its impregnating properties, conventional techniques for printing on impregnated paper
Although printing defects are unavoidable, the method of this invention
Since printing is performed on a film with a smooth surface and laminated as is, it is possible to produce a decorative board with excellent design without the printing ink sticking (no ink leakage).
