ABSTRACT:
Process for preparation of dot-etched photopolymerizable lithographic film which comprises (a) exposing imagewise a photopolymerizable element consisting essentially of a support bearing (i) layer of acid soluble photopolymerizable composition having dispersed therein a chemically soluble pigment; or (ii), in order, (a) layer of acid soluble photopolymer having dispersed therein chemically soluble pigment, (b) layer of clear, unpigmented acid soluble photopolymer composition; or (iii), in order, (a) nonphotosensitive layer of an aqueous soluble polymeric binder having dispersed therein chemically soluble pigment, (b) layer of clear unpigmented acid soluble photopolymer composition, and optionally on each of said elements an overcoat layer; (b) developing the exposed element with acid solution; and (c) treating the developed element with a chemical solubilizing agent for the pigment. Lithographic films are prepared.
