In-mold molding method and in-mold transfer film and manufacturing method thereof

摘要

In the in-mold molding method of the present invention, an in-mold transfer film having a transfer portion (31) of a hard coat layer (3) and a printing layer (32) is placed in a cavity of an injection molding die (101, When the molded product molded by filling the cavity with the molding resin (104) is opened and removed, the transfer part (31) transferred to the molding resin is peeled off from the base film (1) of the in-mold transfer film A method for molding, characterized in that the required elongation percentage of the in-mold transfer film on the side surface of the molded article is A%, the elongation at break of the hard coat layer (3) on the side surface of the molded article is A% + 2% , And the hard coat layer (3) is broken in the mold opening step while setting the range of A% + 40%. With this configuration, peeling of the in-mold transfer film during in-mold molding can be stabilized.
