Summary: | PROBLEM TO BE SOLVED: To provide a plastic molded article for a bumper with excellent finishing appearance. SOLUTION: A decorative film for molding a plastic which is a film laminated successively with a polyolefin film layer, a primer layer, if necessary, a top coat layer and a releasable film layer and wherein the primer layer is a film formed of an isocyanate-curable resin compsn. prepd. by compounding a hydroxyl group-contg. resin (A) with a hydroxyl group value of 30-200 KOHmg/g on average and an Mw of 1,000-80,000, a polyolefin resin (B) and a (blocked) polyisocyanate compd. (C) by 0.1-0.9 isocyanate group of the ingredient (C) per one hydroxyl group of the ingredient (A) and 1-90 wt.% ingredient (B) per total ingredients (A)-(C) in terms of wt. and the film has a static glass transition temp. of 20-70 deg.C, an elongation of at least 10 % and a tensile force of at least 0.5 kgf/mm2, is provided. In addition, an injection-molded article prepd. by setting the decorative film in a mold and injection-molding a polyolefin resin, is provided. |
