Abstract
The invention is directed to resins which are the reaction product of an amino or mercapto substituted azole and a polyepoxide wherein the ratio of equivalents of the azole to the polyepoxide is from about 0.5:1.0 to about 1.5:1.0, preferably from about 0.9:1.0 to about 1.1:1.0. The resins can be acid or base solulized depending on whether amino or mercapto substituted azoles were used in their preparation. The invention is also directed to storage stable compositions which cure at relatively low temperatures in short periods of time comprising specified amounts of the resin containing azole-functionality, polyepoxides, organic solvents, and optionally pigments and additives.
