Acetoacetate-functional monomers are disclosed that correspond to the following formula 1: in which R is hydrogen, or a methylgroup; X is a branched alkyl or a branched cyclic alkyl having from 5 to 8 carbon atoms; and Y1 and Y2 are independently hydrogen or methyl. Also disclosed are emulsion, suspension, and solution polymers comprising residues from the acetoacetate-functional monomer of formula 1 and one or more additional ethylenically unsaturated monomers. Self-curing coating compositions are likewise disclosed that comprise the acetoacetate-functional monomer of formula 1, and optionally one or more additional ethylenically unsaturated monomers. Latex formulations are also disclosed that comprise a polymer having residues from the acetoacetate-functional monomer of formula 1 dispersed in an evaporable aqueous carrier.
