<p>A glycidylester composition produced by reacting a carboxyl functional polyester compound wherein the carboxyl functional polyester resin mainly are produced by reacting: (a) at least one compound A, said compound A is an anhydride having formula (VIII) wherein R and R' each independently represents hydrogen or an alkyl group having from 1 to 4 carbon atoms connected to the cyclohexane ring or together may form a cyclohexane ring, or a diacid containing one secondary acid group and one tertiary acid group; (b) at least one compound B, said compound B has an oxygen content of at most 35 wt% and contains two aliphatic or cycloaliphatic hydroxyl groups and is a di-secondary hydroxyl compound or a di-primary hydroxyl compound which does not contain beta hydrogen atoms and contains at least three carbon atoms between the two hydroxyl groups. Said carboxyl functional polyester compound being substantially free of unreacted diacid monomers.</p> |
