ABSTRACT:
Painting of an article formed of a synthetic resin, e.g. an automobile bumper formed of polyurethane resin, is accomplished by simplified operations and at reduced cost by using a paint of a desired color containing 5-40 wt % of an aprotic polar solvent, preferbly N-methyl-2-pyrrolidone. The paint is applied directly to a cleaned surface of the plastic article, followed by usual drying and baking. Application of a usual primer is omitted since the paint containing an adequate amount of aprotic polar solvent is excellent in adhesion to plastic surfaces. The obtained paint film is comparable to an ordinary top coat paint film formed on a primer layer in appearance, whether resistance and chemical resistance. When a two-toned paint coat is wished, another paint not containing any aprotic polar solvent is applied onto a selected area of the initially formed paint film, followed by drying and baking.
