Photopolymerizable copying compositions containing biuret-based polyfunctional monomers

Abstract

Abstract This invention relates to a photopolymerizable copying composition comprising at least one binder, at least one photoinitiator, and at least one polymerizable, acid amide group-containing acrylic acid derivative or alkyl acrylic acid derivative which is not volatile at 100° C and contains at least two polymerizable groups in the molecule, the polymerizable compound containing at least one compound of the following general formula A(--X--NH--CO--G).sub.p wherein: A stands for Z(--CO--NH--) 2 wherein Z is ##STR1## --O--CH 2 --C q H 2q --O--, or --O--(CH 2 CH 2 --O--) r Wherein q is a whole number from 1 to 11, and r is a whole number from 1 to 5, or for E--C(--CH.sub.2 --O--CO--NH--).sub.3 wherein E is CH 3 --, C 2 H 5 -- or --NH--CO--O--CH 2 --, G stands for ##STR2## or ##STR3## wherein n is 0, 1, or 2, m is a whole number from 1 to 11, k is 0 or a whole number from 1 to 4, R 1 is alkyl with 1 to 3 carbon atoms, or --R 4 or --CH 2 --R 4 , R 2 and R 3 , which may be the same or different, are --H, --CH 3 , or --CH 2 R 4 , and R 4 is ##STR4## and is present in at least one of the groups R 1 , R 2 , and R 3 , X stands for a saturated or unsaturated bi-valent hydrocarbon group with 2 to 12 carbon atoms, and p is a whole number from 2 to 4.
