Abstract: A decorative film for a vehicle exterior of an embodiment of the present disclosure includes a resin layer and an adhesive layer, wherein tearing strength of the resin layer is approximately 8.0 N or more at 20° C., the adhesive layer includes a reaction product of a crosslinking agent and a (meth)acrylate polymer obtained from a material containing a monoethylenically unsaturated monomer and an unsaturated monomer containing a carboxyl group, a glass transition temperature of the (meth)acrylate polymer is approximately −58° C. or more and approximately −40° C. or less, and the unsaturated monomer containing a carboxyl group is incorporated by an amount of approximately 3 mass % or more and approximately 10 mass % or less of a total amount of 100 mass % of the monoethylenically unsaturated monomer and the unsaturated monomer containing a carboxyl group is described. The decorative film may be capable of reducing a defect such as lifting p even in exposure to wind, rain, wind pressure and the like.

Abstract: The present disclosure relates to a method for manufacturing the laminated film that is BSPC (Back Side Printable Clear) and has excellent interlayer adhesion. The method involves a first UV curing step and a second UV curing step and the laminated film includes a transparent film layer, a UV curable ink layer, and an adhesive layer. The first UV curing step includes disposing the UV curable ink layer on the transparent film layer and partially curing the UV curable ink layer by performing a first UV irradiation. The second UV curing step includes disposing the adhesive layer on a surface of the UV curable ink layer opposite the transparent film layer, and further curing the UV curable ink layer by performing a second UV irradiation.
