Abstract
The specification describes various polymers having monomer of formula (I): ##STR1## In formula (I), R1 and R2 are, independently, hydrogen, a C.sub.1 -C.sub.24 alkyl group, an aromatic or heteroaromatic group, a C.sub.3 -C.sub.8 cycloalkyl or C.sub.2 -C.sub.7 heterocycloalkyl group, or a --C(O)R3 group. Preferably R1 and R2 are both a a --C(O)R3 group where R3 which can the same of different is selected from the group consisting of a C.sub.1 -C.sub.24 alkyl group, an aromatic or heteroaromatic group, a C.sub.3 -C.sub.8 cycloalkyl or C.sub.2 -C.sub.7 heterocyclic group; or a --CH.sub.2 --C(O)--R4 group in which R4 is a C.sub.1 -C.sub.6 alkyl group. At lease one of R1 and R2 is a --C(O)R3 group. The polymer may be a homopolymer or a copolymer containing other ethylenically unsaturated monomers. The polymer may be used in a variety of coating compositions such as inks, adhesives, paints and films. Unique monomers where both R1 and R2 are acetoacetyl groups and novel monomers where R2 is an acetoacetyl group are also described.
