US 6,232,433 B1 · Radiation curable polyesters

Abstract

A composition comprising the reaction product of: a) a polycarboxylic member selected from the group consisting of polycarboxylic acids comprised of a diacid having more than about 12 carbon atoms and reactive derivatives thereof (e.g. alkyl esters thereof wherein the alkyl group has from 1 to 4 carbon atoms), b) an ethylenically unsaturated member selected from the group consisting of ethylenically unsaturated mono-carboxylic acids and reactive derivatives thereof, (e.g. alkyl esters thereof wherein the alkyl group thereof has from 1 to 4 carbon atoms), and c) an ethoxylated alkanetriol having an average degree of ethoxylation per hydroxyl of less than about 2 and comprised predominantly of ethoxylated alkanetriol species having one ethoxylate group per hydroxyl. This composition is useful as a polymerizable component, particularly for UV curable coatings and inks.
