Abstract
A heat-curable resin composition obtained by mixing (A) a polyester resulting from the depolymerization of a polyester of a high degree of polymerization comprising an aromatic dicarboxylic acid and an aliphatic dialcohol using a compound containing about 2 to about 12 carboxyl groups per molecule with (B) a polyoxirane compound containing about 2 to about 100 oxirane groups per molecule. A heat-curable resin composition obtained by adding to the above resin composition a salt formed between an aliphatic monocarboxylic acid containing 2 to 20 carbon atoms and an element of Group II of the Periodic Table as a curing accelerator is an especially superior material for powder paints. Powder paints prepared from these heat-curable resin compositions provide coatings having superior appearance and properties upon baking after coating by a method such as an electrostatic spray coating method or a fluidized dip coating method.
