ABSTRACT:
A photosensitive composition is described, which contains a diazonium salt polycondensation product and a polymeric binder which is soluble or at least swellable in aqueous-alkaline solutions and comprises a reaction product of a trimellitic anhydride, the free carboxyl group of which is esterified with an alcohol containing a urethane group, with a polymer containing hydroxyl groups and having no further functional groups capable of reaction with acid anhydrides. The composition yields an increased print run and has, at the same time, good storability and developability.
