<p><P>PROBLEM TO BE SOLVED: To provide a thick decorative sheet made of a thermosetting resin having low dimensional shrinkage. <P>SOLUTION: A prepreg as a core layer 2, which is obtained by impregnating a woven or non-woven fabric of an inorganic fiber with a slurry containing an organic resin component, calcium carbonate and a silane coupling agent and by drying, is subjected to heat press molding together with a dried, resin-impregnated decorative paper 1, which is obtained by impregnating a decorative paper with a resin liquid consisting mainly of a thermosetting resin and by drying. The combination ratio of the organic resin component and the calcium carbonate is 1:3-20 based on a weight ratio of the solids, and as the calcium carbonate there are used a plurality of kinds having an average particle size in the range of 1-5μm. The combination ratio of the organic resin component and the silane coupling agent is 1:0.01-0.5 based on a weight ratio of the solids. The content of the slurry in the prepreg is set to 500-2,000%. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
