RADIATION CURABLE INKJETTABLE ADHESIVE

摘要

A radiation curable inkjettable adhesive composition combining the advantages of radical and cationic cure is described. The composition includes an acrylate ester of carboxylate acid ester, copolymerized with a di-functional component, which is preferably an aliphatic epoxy, utilizing both a photocation polymerization initiator and a free-radical photoinitiator. The adhesive composition is advantageously utilized in drop-on-demand printheads, resulting in a polymeric film having dark cure and excellent adhesion to multiple substrates.
