ABSTRACT:
A process for forming a cured paint film from a paint containing, as a binder, a resin containing a carbonyl group, or a resin, or a resin mixture containing a carbonyl group and a carboxyl group or a paint containing, as a binder, a resin containing a resin or a resin mixture containing a group which forms a carboxyl group in the subsequent contact step with a hydrazine compound or polyhydrazide compound. The uncured paint film, which contains a carbonyl group, or a carbonyl group and a carboxyl group or a group that forms a carboxyl group, is subjected to a step of curing the paint film by allowing the uncured paint film to contact with a hydrazine compound or a polyhydrazide compound.
