Patent ID: 6946088

Claim:
Thermosetting coating material comprising (A) a carboxyl-functional polyester produced by a condensation reaction from aliphatic and/or cycloaliphatic polyols with aliphatic and/or cycloaliphatic and/or aromatic polycarboxylic acid and anhydrides, the polyester having a Tg in the range of 30° C. to 80° C. and an acid value of approximately 20 to 100 (mg KOH/g), and/or comprising a carboxyl-functional polyacrylate produced by polymensation of unsaturated compounds, the polyacrylate having an acid value of 20 to 300 (mg KOH/g), and (B) a β-hydroxyalkylamide which is defined by Formula I, R1 being hydrogen or C1-C5 alkyl and R2 being wherein R1 has the previously indicated meaning and that one or two OH groups are masked and A is a chemical bond or a monovalent or multivalent organic group derived from saturated, unsaturated or aromatic hydrocarbon groups including substituted hydrocarbon groups with 2 to 20 carbon atoms, m is 1 to 2, n is 0 to 2 and m+n is at least 2, the equivalent ratio of β-hydroxyalkylamide equivalents to carboxylic acid equivalents being within the range of 0.6 to 1.6:1.
