摘要:
A photosensitive lithographic printing plate precursor and a method for the preparation of a lithographic printing plate is described, said precursor comprising a support, a non-silver photosensitive layer and a photographic silver halide emulsion coating, and exhibiting photographic camera speed and a printing durability equivalent to the conventional type presensitized plate due to the underlying non-silver photosensitive layer; the silver halide emulsion coating contains a compound represented by the formual (I)R.sup.1 NHNHCOR.sup.2 (I)in which R.sup.1 represents an aryl group and R.sup.2 represents hydrogen, an aryl group, or an aliphatic group.
