Embodiment Construction

[0079] Hereinafter, the manufacturing method of the in-mold decoration molded article of this invention is demonstrated based on embodiment.

[0080] It should be noted that, for the Figure 7 ~ Figure 9 Components having the same function are assigned the same reference numerals and described.

[0081] figure 1 An enlarged cross-section in the width direction of the in-mold transfer foil 20 used in the manufacturing method of the in-mold decorative molded article of the present invention is shown. figure 2 Shows its front view.

[0082] In-mold transfer foil 20 forms in-mold blank 21 by forming release layer 12 , surface protection layer 13 , and primer layer 14 on base film 11 . The release layer 12, the surface protection layer 13, and the primer layer 14 are formed by a coating method such as gravure coating and slot die coating.

[0083] The base film 11 mainly uses polyethylene terephthalate (PET: Polyethylene Terephthalate) as a material, and can also be comprised...
