Abstract
A film-forming halogenated photopolymerizable composition, 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 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, (4) has a glass transition temperature (Tg) between 20.degree. C and the thermal decomposition point of the polymer; b) 20 to 60% by weight of at least one monomeric organic compound containing at least two acrylic acid and/or methacrylic acid radicals and containing from 0 to 65% by weight of active halogen atoms; c) 0 to about 40% by weight of at least one monomeric organic compound containing an acrylic acid or methacrylic acid radical and containing from 0 to about 65% by weight active halogen atoms; d) about 1 to about 25% by weight of a photoinitiator 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 nitr…
