Abstract

PURPOSE: To obtain the titled colored moldings having no color shading by a method wherein hydrogenated bisphenol group unsaturated polyester resin containing a styrene monomer and polystyrene powder and the like are used as blanks, and thermocompression-molded together with a colorant, etc.
CONSTITUTION: Hydrogenated bisphenol group unsaturated polyester resin containing a styrene monomer and polysturene powder are employed as molding blanks, and a viscosity increasing agent such as magnesium oxide, a hardening initiator such as t-butylperoxybenzoate, a release agent such as calcium stearic acid, a filler such as calcium carbonate, a reinforcing agent such as glass fiber and a colorant are added to the blanks. the molding material is heated, pressed and molded, and colored moldings as targets are obtained.
