Abstract:
A coating composition comprisinga self cross-linking functionalized polymer having functionally active cross-linking groups, the self cross-linking polymer further comprising the partial reaction product of a) a cleavable carbonyl polymer having a cleavable unit containing an activated carbonyl group adjacent to an oxygen or a nitrogen atom, the activated carbonyl group being in the polymer backbone, the cleavable polymer having a weight average molecular weight of greater than 10,000 and less than 300,000; and b) a polyester multifunctional compound, polymer or oligomer having a weight average molecular weight of less than 2,000, the polyester multifunctional compound, polymer or oligomer having at least one functionally reactive group capable of reacting with the cleavable carbonyl polymer to cleave the polymer at the activated carbonyl group and form a bond with the cleaved polymer, the polyester multifunctional compound, polymer or oligomer having at least one functionally active cross-linking group.
