Abstract: This invention is directed to optical adhesives useful in light transmitting devices, and more particularly to fluorosubstituted monoacrylate based adhesives having low refractive index. The optical adhesive of the present invention is soluble in organic solvents, and in particular, in non-fluorinated organic solvents. The polymer of the optical adhesive of the present invention has a low glass transition temperature and has the ability to bond well with substrates, including glass substrates and polyethylene terephthalate polyester film substrates typically used in optical devices. The invention is further directed to transfer tapes comprised of at least one layer of a fluorosubstituted monoacrylate based adhesive.

Abstract: A transparent and low refractive index optical coating for use in light transmitting electronic devices is disclosed. The optical coating comprises a hydrogel having a refractive index of less than 1.40.

Abstract: There is provided a curable pressure-sensitive-adhesive layer comprising an interpolymerized hard-monomer system including one alkyl methacrylate present in an amount up to about 25% by weight, based on the total weight of the monomers, and a soft-monomer system present in an amount of from about 50% to about 95% by weight, and comprising at least one alkyl monoester or diester of an unsaturated dicarboxylic acid containing 4 carbon atoms wherein each alkyl group independently contains from 4 to about 8 carbon atoms, the monoester or diester being present in a total amount of up to about 30% by weight, based on the total weight of the monomers, and at least one alkyl acrylate. Cure occurs by electron-beam radiation or by ultraviolet radiation, the former at a dosage of up to 200 kiloGray, after application to a substrate. A multifunctional monomer may be used to enhance radiant-energy cure.
