PROBLEM TO BE SOLVED: To provide a method for producing a thermoplastic resin molded article excellent in appearance of a coating film, wherein the surface of the thermoplastic resin molded article is coated with a coating agent in a molding die. SOLUTION: A thermoplastic resin molding material colored in a predetermined color is molded by an injection molding method or an injection compression molding method in a cavity formed by a movable mold and a fixed mold, and is molded in the same mold. Then, a coating agent is injected between the obtained molded product and the inner wall of the mold, and after the coating material is cured, the coated molded product is removed from the mold. The coating agent comprises the following components: (A) at least one oligomer having at least two (meth) acrylate groups, or at least one unsaturated polyester resin 100 parts by weight (B) ethylenically unsaturated monomer 20 to 200 parts by weight ( C) A scaly pigment having an average particle size of 5 to 150 μm and an aspect ratio of 1.5 to 100. 0.1 to 25 parts by weight of (D) a polymerization initiator containing 0.5 to 15 parts by weight, and a hiding ratio of which is applied. When the volume is 1 ml / 100 cm 2 , it is 0.6 or less. |
