Optical Adhesive With Diffusive Properties

摘要

Optical adhesives that also diffuse visible light include a blend of an adhesive matrix which is an optical adhesive and a block copolymer. The adhesive may be a pressure sensitive adhesive and contains either acid or basic functionality. The block copolymer, which may be a diblock copolymer, contains a high Tg block and a functional block, the functionality of the functional block is complimentary to the functionality of the adhesive matrix to form an acid-base interaction. The adhesive may also contain a crosslinking agent.
