This invention is directed to a setting resin composition for making artificial marble, comprising (A) a radically polymerisable monomer, (B) a thermoplastic resin soluble or dispersible in the monomer (A), (C) an epoxy resin, (D) at least one polyfunctional carboxylic acid compound selected from said group consisting of polyfunctional carboxylic acids and anhydrides thereof, and (E) an inorganic filler. The components are present in proportions such that, based on 100 parts by weight of the radically polymerisable monomer (A), the amount of the thermoplastic resin (B) is in the range of 5 to 75 parts by weight, that of the epoxy resin (C) in the range of 10 to 100 parts by weight, that of the inorganic filler (E) in the range of 100 to 1,000 parts by eights, and that of the polyfunctional carboxylic acid compound (D) in the range of 0.5 to 4.0 equivalent weights per equivalent weight of the epoxy resin (C), and in which an acid anhydride group is assumed to be bifunctional.
