Patent ID: 6949297

Claim:
A curable adhesive composition comprising polyacrylate component comprising an acrylic acid reactive functional group, epoxy component, and cationic initiator, wherein the uncured adhesive exhibits properties of a pressure sensitive adhesive and is optically clear such that the luminous transmission of the composition is greater than 90%, the haze of the composition is less than 2%, and the opacity of the composition is less than 1%, wherein the uncured, curable adhesive can be cured to form an adhesive comprising an inter-reacted interpenetrating polymer network, and wherein after aging the cured adhesive at 90° C. for 500 hours the luminous transmission of the cured and aged adhesive is greater than 90%, the haze of the cured and aged adhesive is less than 2%, and the opacity of the cured and aged adhesive is less than 1%.
