Abstract
Described herein is a coating composition including (A) a physically curing, reactively self-curing and/or externally curing component, including, based on a total solids content of component (A), from 0.1% by weight to about 2.5% by weight of a branched polyester polyol, preparable by: (a) reacting a polyol including at least three hydroxyl groups with an aliphatic dicarboxylic acid having from 6 to 36 carbon atoms or an esterifiable derivative of the aliphatic dicarboxylic acid to form a hydroxyl-functional first intermediate product; (b) reacting the first intermediate product with a cyclic carboxylic acid anhydride to form a carboxylic acid-functional second intermediate product; and (c) reacting the second intermediate product with an epoxide-functional compound having one epoxide group to form the branched polyester polyol; and (B) a crosslinking component in case component (A) includes one or more externally curing components; and optionally (C), a diluent component.
