Abstract
Abstract Polymers comprising the reaction product of: A. unsymmetrical disubstituted hydrazine and B. a material selected from the group consisting of: 1. EPOXY-ESTERS HAVING AT LEAST ONE REACTIVE EPOXIDE GROUP AND AT LEAST ONE REACTIVE CARBOXYLIC ACID ESTER GROUP, AND 2. MIXTURES OF POLYEPOXIDES HAVING A PLURALITY OF REACTIVE EPOXIDE GROUPS AND POLYESTERS HAVING A PLURALITY OF REACTIVE ESTER GROUPS. These polymers find utility as decorative and/or protective coatings when applied to substrates.
