ABSTRACT:
A method for finish coating on polyurethane formed articles, which comprises formulating a finish coating composition so as to have a content of pyrrolidone or its derivative represented by the general formula ##STR1## in which R stands for hydrogen or an alkyl group having at the most 4 carbon atoms, in an amount of 5-40% by weight upon the coating, applying this finish coating composition on the polyurethane formed article directly and heating the so called polyurethane formed article at a temperature of at least 50.degree. C. but lower than the thermal deformation temperature of the polyurethane formed article, said method being capable of attaining a coating layer exhibiting both the properties for a primer coat, namely, a better adhesion onto polyurethane formed articles, and for a finish coat, namely, better weather resistance, higher chemical resistance, favorable appearance and so on, with only a single application and permitting thus to dispense with the primer coating and the heat drying procedure therefor.
