    • A granitic stone ( so-called Mikage-ishi)-like artificial solid material produced by impregnating a paper sheet having a granitic pattern with a thermosetting resin to give a paper containing from 25 to 60% by weight of the resin at the dry basis; drying the resin-impregnated paper sheet; and hot-pressing a laminate comprising a plurality of the dried sheets; is claimed, said paper mainly comprising (A) from 20 to 80% by weight of cellulose pulp, (B) from 2 to 40% by weight of an artificial fiber, (C) from 10 to 70% by weight of an inorganic filler less than 10 .mu.m in average diameter, and (D) from 1 to 30% by weight of a fine-grained additive consisting of grains from 10 to 500 .mu.m in average diameter, having a color hue different from that of the inorganic filler (C).The artificial granite solid material has an excellent machinability, workability, and physical properties (strength), as well as good-looking textures (inorganic material like appearance, expressing by itself heaviness, hardness, and thickness; exhibits a very granitic look as a whole) with an ornamental and luxurious appearance.
    • 通过用热固性树脂浸渍具有花岗岩图案的纸张制成的花岗石(所谓的Mikage-ishi)样人造固体材料,得到以干基计含有25至60重量%的树脂的纸; 干燥树脂浸渍纸片; 和热压包含多个所述干燥片材的层压体; 所述纸主要包含(A)20-80重量%的纤维素纸浆,(B)2至40重量%的人造纤维,(C)10至70重量%的无机填料 平均直径小于10微米,(D)1〜30重量%的由平均直径为10〜500μm的粒子组成的细粒添加剂,其色调与无机填料的颜色不同 (C)。 人造花岗岩固体材料具有优异的机械加工性,可加工性和物理性能(强度)以及良好的纹理(无机材料如外观,本身沉重,硬度和厚度表现出来)表现出非常花式的外观 )具有装饰和豪华的外观。
