ABSTRACT:
The invention relates to a coating composition suitable for application to plastic surfaces. The coating composition comprises, as essential components, 100 parts by weight of a chlorotrifluoroethylene based copolymer having hydroxyl group as a functional group, a curing agent for the copolymer such as a polyisocyanate, 0.5-30 parts by weight of an acrylic or methacrylic polymer which serves as an adhesion improving component, and an organic solvent. Usually the composition contains an ultraviolet absorber and another light stabilizer. For example, on a polycarbonate article this composition provides a durable coating film without marring the transparency and healthiness of the polycarbonate substrate. By the addition of a pigment the coating is modified into a paint composition which is particularly useful for repairing a bake finished paint film formed by using a polyvinylidene based paint.
