Abstract This invention relates to a light-sensitive copying composition which contains from 65 to 99 per cent by weight of at least one copolymer containing from 10 to 55 mole per cent of N-allylmaleimide units, from 0 to 15 mole per cent of maleic acid units and from 45 to 80 mole per cent of units of the formula -CH2-CHZ, wherein X is selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl or alkoxy group containing from 1 to 3 carbon atoms, an aryl group or an acyloxy group, and Z is selected from the group consisting of a hydrogen atom, a halogen atom or an alkyl group containing 1 to 2 carbon atoms, from 0 to 35 per cent by weight of at least one photopolymerizable compound having at least two vinyl or vinylidene groups in the molecule and which boils above 100*C under standard pressure, and from 1 to 8 per cent by weight of at least one photoinitiator.
A LIGHT-SENSITIVE COPYING COMPOSITION WHICH CONTAINS FROM 65 TO 99 PERCENT BY WEIGHT OF AT LEAST ONE COPOLYMER CONTAINING FROM 10 TO 55 MOLE PERCENT OF N-ALLYL-MALEIMIDE UNITS, FROM 0 TO 15 MOLE PERCENT OFF MALEIC ACID UNITTS AND FROM 45 TO 80 MOLE PERCENT OF UNITS OF THE FORMULA
