PROBLEM TO BE SOLVED: To provide an acrylic artificial marble which is excellent in the antifungus property, productivity, appearance, heat resistance, weatherability and hot-water resistance. SOLUTION: This acrylic premix, comprising (a) methyl meth-acrylate or a (meth)acrylic monomer mixture, (b) a poly(methyl methacrylate) or an acrylic copolymer, (c) an inorganic filler and (d) an inorganic antifungus agent, is characterized in that (d) the inorganic antifungus agent contains at least one kind of (d1) an inorganic antifungus agent of a sintered product made by supporting an antifungus metal on a phosphate and sintering, and (d2) an inorganic antifungus agent produced by supporting an antifungus metallic ion on a zinc and calcium salt of phosphoric acid by chemical bond. An acrylic SMC or BMC contains the acrylic premix and a polymer powder. A preparative process for an acrylic artificial marble comprises heating, pressing and curing the acrylic SMC or BMC at a temp. ranging from 90 to 150 deg.C.
