Title:
POLYESTER RESIN, METHOD FOR PRODUCING POLYESTER RESIN, AND COATING COMPOSITION INCLUDING POLYESTER RESIN
Document Type and Number:
WIPO Patent Application WO/2015/163400
Kind Code:
A1
Abstract:
Provided is a polyester resin having excellent solubility in general-purpose solvents, particularly at a temperature of 0°C or below. By using this polyester resin having excellent solubility in general-purpose solvents, solubility can be improved at low temperatures, particularly at or below 0°C, and paints, coating agents, and the like are easily adjusted. This polyester resin includes, with respect to 1 mole of a structural unit derived from a polyvalent carboxylic acid, 0.05 to 0.5 moles of a structural unit derived from isosorbide, and 0.015 to 0.4 moles of a structural unit derived from a trivalent or higher alcohol.
