International ClassesC09J 109/02C09J 133/08 AbstractThe current invention provides a photopolymerized pressure-sensitive adhesive which adheres well to all common surfaces and has an outstanding ability to bond to plasticized vinyl substrates and to remain firmly bonded thereto even after remaining in contact therewith for extended periods of time comprising an acrylic copolymer and a nitrile butadiene rubber or mixture of rubbers. Preferred pressure-sensitive adhesives of the invention comprise from about 1 to about 10 parts of the nitrile rubber or a mixture thereof.Other References
