  • Patent number: 5462797
    Abstract: The present invention provides a pressure-sensitive adhesive composition and a method for producing the same. The pressure-sensitive adhesive composition is produced by the combination of at least one free-radically photopolymerizable monomer and at least one set of polyurethane precursors, and a suitable photoinitiation system consisting of at least one salt of a cationic organometallic complex, an additional free-radical photo initiator and the application of sufficient energy to photopolymerize same by sequential exposure to visible electromagnetic radiation and then to ultraviolet electromagnetic radiation.
