摘要:
A curable resin composition may include a component having two or more active methylene groups and/or active methine groups, a component having at least two α,β-unsaturated carbonyl groups, and a triphenylphosphine catalyst that promotes a Michael reaction between the other two components. The composition can be used to coat metal substrates and can exhibit particularly good performance characteristics when applied to unprimed, bare metal surfaces.
