Abstract: An in-mold molding method of the present invention is a method including: placing an in-mold transfer film in the cavity of an injection molding mold, the in-mold transfer film having a hard coating layer and a transfer section of a printed layer; and peeling, from the base material film of the in-mold transfer film, the transfer section transferred to a molding resin when a molding molded by injecting the molding resin into the cavity is removed by mold opening. The hard coating layer is ruptured in a mold opening process while the in-mold transfer film has a necessary elongation of A % on the side of the molding and the hard coating layer has a rupture elongation of at least A %+2% and less than A %+40% on the side of the molding. With this configuration, the in-mold transfer film can be stably peeled during in-mold molding.

Abstract translation: 本发明的模内成型方法是将模内转印膜配置在注射成型模具的型腔内的方式，具有硬涂层和印刷层的转印部的模内转印膜 ; 并且通过模具开口去除通过将模制树脂注入到模腔中而成型的模制树脂时，从模内转印膜的基材膜剥离转印部。 模内转印膜在模制品侧具有必要的A％伸长率，硬质涂层在开模过程中破裂，硬涂层的断裂伸长率至少为A％+ 2％以下 比成型品侧面的A％+ 40％。 通过这种构造，可以在模内成型时稳定地剥离模内转印膜。
