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.
