A granitic stone (so-called Mikage-ishi)-like artificial solid material produced by impregnating a paper sheet having a granitic stone-like fleck 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 sheet; 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 µm in average diameter, and (D) from 1 to 30 % by weight of a fine- grained additive consisting of grains from 10 to 500 µm in average diameter, having a color hue different from that of the inorganic filler (C). The granitic stone-like artificial 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, arid thickness; exhibits a very granitic stone-like looking as a whole) with an ornamental and luxurious appearance.
