Abstract
The present invention relates to an alkyd resin comprising the condensation product of at least the following components (A) a polybasic acid, (B) a polyhydric alcohol, and (C) a linear C12-C60 hydrocarbo monocarboxylic acid, and optionally (D) at least one component other than any of components A to C characterized in that at least a part of the polybasic acid (A) is a (optionally hydrogenated) Diels Alder adduct of citraconic acid with C4-C14 conjugated diene, a (optionally hydrogenated) Diels Alder adduct of citraconic anhydride with C4-C14 conjugated diene, a half ester of such a Diels Alder adduct and/or a diester of such a Diels Alder adduct.
Claims21
An alkyd resin comprising the condensation product of at least the following components:
- (A) a polybasic acid,
- (B) a polyhydric alcohol, and
- (C) a linear C12-C60 hydrocarbo monocarboxylic acid, and optionally
- (D) at least one component other than the components (A) to (C), wherein
