The invention relates to enamine resins which are the reaction products of a) an acetoacetylated resin, and a C.sub.1-C.sub.20 alkyl amine or a mixture of C.sub.1-C.sub.20 alkyl amines. The acetoacetylated resin is the reaction product of a polyol having 4 or more hydroxyl groups; and at least one acetoacetate. The invention also relates to an acetoacetylated resin which is the reaction product of a polyol having 4 or more hydroxyl groups and at least one acetoacetate, where a portion of the hydroxyl groups of the polyol are replaced by acetoacetate groups and the remaining hydroxyl groups are replaced by a saturated monofunctional carboxylic acid ester, unsaturated monofunctional carboxylic acid ester, or a mixture thereof; as well as to enamine resins prepared from these acetoacetylated resins. The invention also relates to curable coating compositions containing such resins or a mixture of those resins, at least one metallic drier compound; and optionally one or more solvents.

Methods of preparing poly(cyanocinnamate)s are provided, with those involving mild conditions and resulting in a soluble polymer that is stable at room temperature and can be coated onto microelectronic substrates. The polymer includes at least one bis(cyanoacetate) monomer and at least one aromatic dialdehyde monomer. The polymer exhibits good thermal and structural properties and high absorbance in the UV range.

A curable composition including a first component containing aldehyde group-containing compounds and a second component containing cyanoacetate group-containing compounds, wherein the average molecular weight Mn of the first and second components, with respect to the aldehyde or cyanoacetate group-containing compounds, ranges from 400 to 20,000 g/mol, and the average functionality of at least one of the two components, with respect to the aldehyde or the cyanoacetate group-containing compounds, is greater than 2.0. The composition is largely free of toxic ingredients and cures in ambient conditions using conventional catalysts quickly and in a trouble-free manner in order to form a non-tacky elastic polymer with a high degree of strength, elasticity, and resistance to tear propagation. The composition is particularly suitable for use as an elastic adhesive, sealant, or coating with a high degree of robustness during production, storage, and processing as well as a high degree of resistance after curing.
