This invention relates to a photosensitive composition, comprising:n (A) a diazonium polycondensation product or na free radical polymerizable system consisting of photo initiators and unsaturated compounds which are free radical polymerizable or na hybrid system consisting of a diazonium polycondensation product and a free radical polymerizable system consisting of photo initiators and unsaturated compounds which are free radical polymerizable, (B) a binder and noptionally one or more exposure indicator(s), one or more dye(s) for increasing the contrast of the image as well as one or more acid(s) for stabilizing the photosensitive composition. n The binder is a reaction product of a carboxyl-groups containing polymer of formula (I) n n P-(-X-COOH) n (I), n nwherein nP is a polymer, nn is an integer and nX is a single bond or a spacer group, nwith one or more different 2-oxazoline(s) of the formula (II)n wherein nR is alkyl, aryl, aralkyl, alkoxy, aryloxy or aralkyloxy and R' and R'' are independently hydrogen, alkyl or aryl and wherein 5 to 100 mole % of the carboxyl groups can be reacted. |
