Radiation-sensitive compositions and elements containing poly(vinyl hydroxyaryl carboxylic acid ester)s
Abstract:
A radiation-sensitive composition can be used to prepare positive-working imageable elements having improved sensitivity and solvent resistance. These elements are useful for making lithographic printing plates and printed circuit boards. The composition includes a water-insoluble polymeric binder that has at least 20 mol % of recurring units comprising hydroxyaryl carboxylic acid ester groups, some of which can be substituted with cyclic imide moieties.
