Abstract

Abstract A solvent-free printing ink or coating composition vehicle which is curable by exposure to a source of radiation comprises (1) the reaction product of the alcoholysis of a fatty acid ester oilmodified epoxy resin or a fatty alkyl ester-modified epoxy resin with an ethylenically unsaturated acid and (2) a photoinitiator. The reaction product may be further modified by reaction with an end-capping agent. Formulations containing these vehicles may also include additional monomeric ethylenically unsaturated esters.
