ABSTRACT:
Process for preparation of dot-etched photopolymerizable lithographic film which comprises (a) exposing imagewise a photopolymerizable element consisting essentially of a support and a layer of caustic soluble photopolymerizable composition having dispersed therein a chemically soluble pigment, e.g., iron oxide, and optionally an overcoat layer; (b) developing the exposed element with caustic solution; and (c) treating the developed element with a chemical solubilizing agent for the pigment. A lithographic film is prepared.
