Photosensitive compositions comprising a) 5-95 % by weight of a polyester of formula I; II or III Image wherein R1 is the radical of a cyclic anhydride of a dicarboxylic acid after removal of the -O-CO-O- grouping, which radical may be substituted by C1-C22alkyl, C5- C10cycloalkyl, C3-C6alkenyl, C6-C10aryl, halogen or C1-C22alkyl which is interrupted by -O- or -CO-O-, R2 is hydrogen, unsubstituted or halogen-substituted C1-C22alkyl, C5- C10cycloalkyl, C7-C12aralkyl, C6-C10aryl or a radical -CH2-O-R5 or -CH2-O-CO-R5, wherein R5 is C1-C22alkyl, C5-C6cycloalkyl or C6-C10aryl, R3 is hydrogen, or R2 and R3, together with the linking carbon atoms, are a cyclopentylene or cyclohexylene radical, R4 is a radical of 4 to 12 carbon atoms which carries an unsaturated end group and carboxyl or ether groups, A is a mono- or polyfunctional low molecular or high molecular carboxylate or alcoholate, x is an integer from 0-100, n is an integer from 2-150, and z is an integer from 1-4, b) 10-90 % by weight of a liquid polyfunctional aliphatic, cycloaliphatic or aromatic (meth)acrylate, c) 0-70 % of a mono(meth)acrylate or mono-N-vinyl compound with a molecular weight of not more than 500, d) 0.1-10 % by weight of a photoinitiator, and e) 0-10 % by weight of optional customary additives.
