CA 2157185

A crosslinkable liquid carrier-based coating composition formulated from components comprising an organic polymer(s) having acetoacetyl group functionality, a polyamine compound(s) having at least two acetoacetyl-reactive amino groups per molecule, and a non- polymeric monoacetoacetyl compound(s) which can evaporate on coating formulation selected from at least one of alkyl acetoacetate, alkyl acetoacetamide and 1-alkyl-1,3-butanedione where said alkyl groups in said compounds have from 1 to 3 carbon atoms, and wherein the ratio of the number of acetoacetyl groups from said monoacetoacetyl compound(s) to the number of polymer-bound acetoacetyl groups from said organic polymer(s) having acetoacetyl group functionality is within the range of from 0.8/1 to 15/1. The preferred monoacetoacetyl compound is methyl acetoacetate.
