Abstract
A tin-containing polyurethane resin having a melting temperature of 40 to 180° C., measured by DSC at a heating rate of 10 K/min and prepared by carrying out a condensation reaction between a diorganotin compound and carboxyl groups of a carboxyl-functional polyurethane resin, wherein the molar ratio between the tin and the carboxyl groups is 1:2-20; and liquid coating compositions containing solid particles of the tin-containing polyurethane resin.
