Radiation-curable pressure-sensitive adhesive having improved adhesion
to plasticized vinyl substrates
Abstract:
The 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 the in contact therewith for extended periods of time comprising the photopolymerization reaction product of a mixture containing about: 60-95 parts of alkyl acrylate; 5-40 parts monoethylenically unsaturated polar copolymerizable monomer; 10-30 parts ethylene vinylacetate copolymer containing about 40% to 70% vinylacetate; and 0.1-1 part photoinitiator.
