DECORATIVE PAPER SHEET HAVING BRIGHTNESS AND THERMOSETTING RESIN DECORATIVE SHEET

摘要

PROBLEM TO BE SOLVED: To prevent the surface irregularity of brightness (feeling) caused at the time of resin impregnation or thermocompression forming when brightness is applied to the design of a thermosetting resin decorative sheet or decorative paper sheet therefor without adding a transparent ink layer to the surface of the decorative paper sheet additionally.

SOLUTION: A bright ink layer 3 containing a brilliant pigment comprising scaly foil pieces of a bright substance is provided on a paper base material 1 as the outermost surface layer and ink, wherein an aqueous resin such as a casein resin, an acrylic resin or the like is used together with a urethane resin emulsion as the resin of the ink of the bright ink layer, is used to obtain the decorative paper sheet 10 having brightness. If a pattern ink layer 2 by usual ink is provided between the ink layer and the paper base material, the design of the decorative paper sheet 10 is further enhanced. The decorative paper sheet 10 is impregnated with a thermosetting resin such as a melamine resin or the like and the impregnated decorative paper sheet is laminated on an adherend 6 such as a backing base material 4 or overlay paper sheet 5 and the whole is subjected to thermocompression forming to cure the resin to obtain the thermosetting resin decorative sheet 20 having brightness.
