Abstract
Halogenated photopolymerizable adhesive, which comprises: (a) 20 to 70% by weight of at least one halogenated polymer, which: (1) has a chain interrupted by at least one oxygen or nitrogen atom, (2) contains from 4 to 70% by weight of halogen atoms attached to carbon atoms having the electronic configuration sp.sup.2, (called "active halogen atoms"), (3) has an average molecular weight between 700 and 10,000 and (4) has a glass transition temperature (Tg) between -80.degree. C and 20.degree. C; (b) 5 to 30% by weight of at least one organic monomer compound containing at least two acrylic and/or methacrylic acid radicals and containing from 0 to 65% by weight of active halogen atoms; (c) 20 to 70% by weight of at least one organic monomer compound containing an acrylic or methacrylic acid radical and containing from 0 to about 65% by weight of active halogen atoms; (d) about 1 to about 25% by weight of a photo-initiator system comprising: (1) 0.5 to 100% by weight of at least one aromatic ketone, (2) 0 to 99.5% by weight of at least one tertiary amine, at least one carbon atom of which, in the alpha position with regard to the nitrogen atom, carries at least one hydrogen atom, (3) …
