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.degree. C and contains at least two polymerizable groups in the molecule, the polymerizable compound containing at least one compound of the following general formula EQU A(--X--NH--CO--G).sub.p wherein: PA1 A stands for Z(--CO--NH--).sub.2 wherein Z is ##STR1## --O--CH.sub.2 --C.sub.q H.sub.2q --O--, or --O--(CH.sub.2 CH.sub.2 --O--).sub.r PA1 Wherein PA2 q is a whole number from 1 to 11, and PA2 r is a whole number from 1 to 5, or for EQU E--C(--CH.sub.2 --O--CO--NH--).sub.3 PA2 wherein PA3 E is CH.sub.3 --, C.sub.2 H.sub.5 -- or --NH--CO--O--CH.sub.2 --, PA3 G stands for ##STR2## or ##STR3## wherein PA4 n is 0, 1, or 2, PA4 m is a whole number from 1 to 11, PA4 k is 0 or a whole number from 1 to 4, PA4 R.sub.1 is alkyl with 1 to 3 carbon atoms, or --R.sub.4 or --CH.sub.2 --R.sub.4, PA4 R.sub.2 and R.sub.3, which may be the same or different, are --H, --CH.sub.3, or --CH.sub.2 R.sub.4, and PA4 R.sub.4 is ##STR4…
