Artificial stone molded product

A process for producing an artificial stone molded product in which embedded grooves for a figure or a pattern are integrally provided in a flat surface of a substrate, a main composition of the stone molded product comprises an aggregate of an inorganic material and a resin, and luminous or fluorescent light-emitting portions are embedded in at least a part of said embedded grooves, so that the light-emitting portions are present only in said embedded grooves, which comprises

• injecting a mixture for resin molding containing an aggregate of an inorganic material into protrusions formed in an inner bottom surface of a mold and corresponding to the embedded grooves of the molded product, curing or half-curing the mixture, withdrawing the product from the mold, injecting a mixture for resin molding containing an aggregate of a transparent inorganic material having a surface baked with a luminous or fluorescent material, having a luminescence or a luminousness accompanied by ultraviolet absorption, as at least a part of the aggregate of the inorganic material into grooves formed in the surface of the molded product, and curing the mixture, wherein the aggregate of the transparent inorganic material baked with the luminous or fluorescent material is contained in the light-emitting portions at a ratio of from 5 to 65% by weight based on the total amount of the composition of the light-emitting portions.
