Abstract
A presensitized lithographic printing plate, which comprises a support having a hydrophilic surface. A non-silver light-sensitive layer capable of having formed therein a lipophilic image pattern and a direct positive light-sensitive silver halide emulsion layer are provided on the support in that sequence. The non-silver light-sensitive layer is provided with an adjacent hydrophilic colloid layer in which a resin is dispersed in fine particle form. The resin is a copolymer comprising (A) a recurring unit derived from at least one monomer of acrylic acid and methacrylic acid, and (B) a recurring unit derived from at least one monomer of an aralkyl acrylate and an aralkyl methacrylate.
