  • Photocured lamina of unsaturated urethane/monomer adhesive blend with a transparent layer
    Patent number: 4355077
    Abstract: A photo-hardenable adhesive composition particularly suitable for use in the bonding of glass to other materials, especially plastics, as in the production of safety glass and armored glass laminates and comprising(A) a photopolymerizable ester of an .alpha.,.beta.-ethylenically unsaturated acid and a hydroxylated urethane or urea and having a molecular weight of 500 to 10,000(B) a photoinitiator(C) a substituted or unsubstituted aliphatic or cycloaliphatic N,N-dialkylamino alcohol ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, said alcohol having an alkylene moiety of up to six carbon atoms between hydroxy and the amino functions, and(D) an .alpha.,.beta.-ethylenically unsaturated carboxylic acid in an amount equal to one mole per mole of C, (C) and (D) being capable of reacting together to form a betaine, and preferably(E) at least one further copolymerizable monomer or oligomer and which may comprise an excess of (C) or (D) over equimolar.
