Zusammenfassung:	This invention relates to a curable composition comprising:I. Component (I) comprising a resin having at least one functional group selected from the group consisting of β-ketoester and malonate functional groups;II. Component (II) comprising at least one curing agent having at least one aldehyde functional group;III. Component (III) comprising at least one amine, salts thereof, or combinations thereof; and, optionallyIV. Component (IV) comprising at least one reactivity delayer; wherein said curing agent is at least one dialdehyde selected from the group consisting of 1,3-cyclohexanedicarboxaldehyde; 1,4 -cyclohexanedicarboxaldehyde; mixtures of 1,3-cyclohexanedicarboxaldehyde and 1,4-cyclohexanedicarboxaldehyde; 2,6-norbornanedicarboxaldehyde; 2,5-norbornanedicarboxaldehyde; cyclododecane-1,4,8-tricarbaldehyde; 3-(4 -formylcyclohexyl)propanal; tricyclodecane dialdehyde; o-phthalaldehyde; terephthalaldehyde; isophthalaldehyde; cyclopentane-1,3-dicarbaldehyde; cyclopenta-3,5-diene-1,3-dicarbaldehyde; glutaraldehyde; benzenedipropanal; any isomers thereof; and any mixtures thereof.
