Abstract:
A process for preparing a decorative film for use in plastics molding, which process comprises coating an isocyanate-curing coating 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, (C) a (blocked)polyisocyanate compound and (E) an organic solvent 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% by weight based on a total weight of the components (A), (B) and (C) onto one side of a polyolefin film layer, followed by drying at normal temperature or by heating to form a primer layer having a static glass transition temperature of 20 to 70Â° C., an elongation of 10% or more and a tensile strength of 0.5 kgf/mm2 or more.
