Abstract:
A decorative film for use in plastics molding and used for obtaining an integrally molded product with the decorative film by a process which comprises setting the decorative film on an inner side of an injection mold and subjecting a molding polyolefin resin to injection molding, said decorative film being a laminate film prepared by outwardly and successively laminating a polyolefin film layer, a primer layer, optionally a topcoating layer and a releasable layer, said primer layer being a coating film formed from an isocyanate-curing resin composition containing (A) a hydroxyl group-containing resin having a hydroxyl number of 30 to 200 KOH mg/g on an average and a weight average molecular weight of 1000 to 80000, (B) a polyolefin resin and (C) a (blocked) polyisocyanate compound in such mixing amounts that a number of the isocyanate group in the component (C) is in the range of 0.1 to 0.9 per one hydroxyl group in the component (A) and that the component (B) is in the range of 1 to 90 percent by weight based on a total weight of the components (A), (B) and (C), and having a static glass transition temperature of 20 to 70Â° C., an elongation of 10 percent or more and a tensile strength of 0.5 kgf/mm2 or more.
