Molding particles are prepared by forming a reaction compound and crushing the reaction compound into a predetermined size. The reaction compound is formed by mixing a starting material A having a plurality of reactive substituent groups, a starting material B reactive with the starting material A, and a monomer 1 in liquid phase which is polymerizable by a radical polymerization reaction, and then linking the starting materials A and B by a reaction other than a radical reaction. A molding compound is prepared by mixing the molding particles with a monomer 2 copolymerizable with the monomer 1. It is thus possible to prepare the molding compound capable of developing desired markings, for example, a so-called streaked, or scrolled appearance. By molding the molding compound, it is possible to easily produce a three-dimensional molding, for example, an artificial stone having an appearance resembling a natural stone, for example, granite and marble, in a simplified manner. |
