<p>PURPOSE:To realize spot patterns having a plurality of hues and sizes by imparting granite like patterns formed by cutting colored paper to constitute a papermaking internal additive for a hot-pressed molded object and using said additive as a design imparting material of a granite like artificial solid material. CONSTITUTION:A papermaking internal additive for a hot-pressed molded object is constituted by imparting or grinding colored paper. At this time, the colored paper is subjected to waterproofing treatment by a thermosetting resin. Further, the colored paper is ground by a grinder to be classified so as to obtain an arbitrary particle size. The papermaking internal additive for the hot-pressed molded object thus constituted is used as the design imparting substance contained in the pattern paper of a granite like artificial solid material and further used in a state added to the overlay or pattern paper of a granite like thermosetting resin decorative panel. By this constitution, spot patterns requiring a plurality of hues and sizes are pref. expressed and a special raw material is made unnecessary.</p> |
