A positive acting, photoimageable composition having, a photoacid generator capable of generating an acid upon exposure to actinic radiation, an organic acid anhydride polymer, an epoxy, a nitrogen-containing curing catalyst, and an optional phenol-containing monomer or polymer. A photographic element has this composition coated and dried on a substrate. A positive acting image is produced by imagewise exposing the element to actinic radiation, optionally postbaking and development with a liquid developer.
