Abstract

The present invention provides a radiation curable composition comprising a hydroxyl functional urethane (meth)acrylate compound (A) having an hydroxyl value between 10 and 80 mg KOH/g and which is the reaction product of a hydroxyl functional (meth)acrylate compound (A1) obtained from the reaction a or b: a. at least one diepoxy functional compound (A11a) with a (meth)acrylate compound (A11b) comprising at least one (meth)acrylate group and one carboxylic acid functional group or b. a carboxylic acid functional compound (A12a) comprising two carboxylic acid groups with an epoxy (meth)acrylate compound (A12b) comprising one glycidyl group and at least one (meth)acrylate group, with a diisocyanate functional compound (A3), and optionally a compound (A2) different of compound (A1) comprising two hydroxyl groups. Such composition is useful for example for dual curable compositions or for thick pigmented systems.
