WIPO Patent Application WO/2024/070325

A1

[Problem] To provide a method for manufacturing an in-mold-coated molded article in which a step for coating an outer surface of a molding base material with a liquid coating agent and a step for forming a desired pattern are performed simultaneously. [Solution] Provided is a method for manufacturing an in-mold-coated molded article 28 in which a molding base material 2 is attached to a first mold 1, the first mold 1 is abutted on a second mold 3 so as to cover the molding base material 2, a coating gap is formed between an inner surface of the second mold 3 and an outer surface of the molding base material 2, and a liquid coating agent (paint 5) is injected into the coating gap 4 and attached to the outer surface of the molding base material 2, wherein a convex part 30 corresponding to a pattern desired to be added to the outer surface of the molding base material 2 is formed on the inner surface of the second mold 3 to a height H corresponding to the coating gap 4, and the liquid coating agent 5 is injected into the coating gap 4 with the first mold 1 abutted on the second mold 3 and with the convex part 30 pressed onto the outer surface of the molding base material 2.
