Patent ID: 7790081

Claim:
A process for producing an in-mold coated molded product, comprising: molding a thermoplastic resin material under a mold-clamping pressure in a mold comprising a fixed mold part and a movable mold part each heated at a predetermined temperature to obtain a molded product; separating the fixed mold part and the movable mold part when a surface of the molded product is solidified to such a degree that the surface is durable to a pressure of injection and flow of a coating agent; injecting the coating agent containing a thermosetting resin material between an inner surface of the mold and the molded product; coating the surface of the molded product with the coating agent as the mold is re-clamped after injecting the coating agent; removing the molded product coated with the coating agent when the coating agent is cured to such a degree that the coating agent is not peeled off nor cracked by opening the mold; and re-heating the molded product after removing the molded product by applying external thermal energy; wherein: the temperature of re-heating the molded product is higher than the temperature of the mold; an organic peroxide is used as an initiator for a curing reaction of the thermosetting resin material; the organic peroxide comprises at least two types of organic peroxides; and at least one of the organic peroxides has a one-minute half-life temperature higher than the temperature of the mold.
