Abstract

PURPOSE: To prepare a coating resin having a sharp molecular weight distribution and improved air-drying property, capable of giving high-strength films, by depolymerizing an unsaturated polyester having a specific molecular weight with a hydroxyl group-containing polyhydric alcohol allyl ether.
CONSTITUTION: A coating resin is prepared by depolymerizing (A) an unsaturated polyester having a molecular weight of 3 x 103 - 106 and free of a polyhydric alcohol allyl ether, with (B) a polyhydric alcohol allyl ether having one or more hydroxyl groups at 150W250°C. As for the component (B), partially allyl-etherified derivatives of trimethylolpropane, glycerol, pentaerythrithol, sorbitol, etc., may be preferably cited.
