。The liquid resin composition (hereinafter referred to as a compound) used for matrix molding in the present invention has a viscosity suitable for cast molding, transparency to the extent that the colored granules described below can be seen through, and a specific gravity equivalent to that of the colored granules. Insofar, it is different from ordinary resin comparands for cast molding. For example, thermosetting epoxy resins, unsaturated polyester resins, and acrylic resins are preferably used as liquid resins. In addition to these resins, compounds can be formulated with transparent or translucent inorganic fillers such as aluminum hydroxide, powdered silica, and glass powder to increase surface hardness and dimensional precision, and to create colored granules as described below. It is preferable to easily adjust the specific gravity with the body.

ものを選択して着色粒状体とする。The resin constituting the colored granules is a solid thermosetting resin with a softening point higher than the curing temperature of the matrix, and epoxy resins, unsaturated polyester resins, acrylic resins, etc. are preferable.0 In order to obtain colored granules, , an inorganic filler such as aluminum hydroxide, powdered silica, glass powder, etc. is mixed with the above-mentioned resin in a proportion such that the difference in specific gravity with the above-mentioned liquid resin compound is 0.2 to +0.5 or less, and if necessary. Additives such as coloring agents such as pigments, curing agents, curing accelerators, various stabilizers, etc. to give any color tone depending on the color, heat and melt, mix, and after cooling, the resulting uncured heat Grind the curable resin mixture. To facilitate grinding, the mixture is preferably obtained in sheet form. The pulverized uncured filler-containing resin is classified, and those having a desired particle size are selected to form colored granules.
