| 摘要 |
The present invention relates to a method for manufacturing an undercoating layer for an in-mold molding film, comprising the steps of: (1) applying an undercoating composition on a substrate and performing heat curing; and (2) irradiating the applied substrate with light with a wavelength of 340-400 nm and maturing the irradiated substrate. The undercoating layer manufactured by the method of the present invention provides high hardness and elongation, thereby being used for manufacturing an in-mold molding film. |
