Abstract
This invention relates to a curable coating composition comprising: I. at least one acetoacetate functional polyester further comprising the residues of a. a hydroxyl component comprising: i. a diol in an amount ranging from 70 to 100 mole %, based on the total moles of (i) and (ii); and ii. a polyol in an amount ranging from 0 to 30 mole %, based on the total moles of (i) and (ii); b. a carboxyl component comprising a polycarboxylic acid compound, a derivative of polycarboxylic acid compound, or a combination thereof; and c. an alkyl acetoacetate, a diketene, or a combination thereof in an amount ranging from about 5 to about 50 weight %, based on the total weight of (a), (b), and (c). II. a curing agent having two or more aldehyde functional groups, and III. a basic catalyst.
