Abstract
A liquid coating composition based on a polymer containing acetoacetate groups and a polyamine in the form of the corresponding aldimine or ketimine, the polymer containing acetoacetate groups being obtained by reacting a polyepoxide containing hydroxyl groups, or a polyepoxide which is partially or completely reacted with monocarboxylic acids, with acetoacetic acid derivatives. These liquid coating compositions are suitable in particular as binders in two-component fillers for automotive refinishing or as two-component primers.
