ABSTRACT:
Polyesters obtained by reacting from 5 to 50 parts of at least one linear or branched, aliphatic or cycloaliphatic, at least dihydric alcohol, from 2 to 40 parts of at least one at least dibasic, aromatic carboxylic acid, from 0 to 40 parts of at least one 2-alkenyldicarboxylic anhydride, from 10 to 30 parts of at least one at least dibasic, linear or branched, aliphatic carboxylic acid, from 0 to 15 parts of an aliphatic, linear or branched hydroxy acid, from 0 to 15 parts of an aliphatic, linear or branched polyamine having at least one primary and at least one secondary or tertiary amino group, from 0 to 15 parts of a glycidyl ester of a branched, aliphatic monocarboxylic acid or of a glycidyl ether of a branched, aliphatic alcohol, and from 0 to 15 parts of polyhydroxyamine are useful, for example, as additives in coating compositions.
