Classification: CPC C  B | IPC B  C

Claim 12:
13. A method of coating a substrate comprising:
mixing a curable resin composition comprising (a) at least one component comprising two or more active methylene groups and/or active methine groups, (b) at least one component comprising at least two α, β-unsaturated carbonyl groups, and (c) from 0.5 weight percent to 7.5 weight percent of a triphenylphosphine catalyst, thereby promoting a Michael reaction between the at least one component comprising two or more active methylene groups and/or active methine groups and the at least one component comprising at least two α, β-unsaturated carbonyl groups;
applying the curable resin composition to a substrate,
wherein the curable resin composition cures at ambient conditions; and
wherein the curable resin composition exhibits a viscosity substantially similar to the viscosity of one or more of (a) or (b) for a period of at least 15 minutes.
