Abstract

The invention relates to lithographic printing plates having improved image stability and visibility. The improvements arise from the use of a photosensitive composition which upon exposure to light forms a bleached, less intense coloring than its original color. The composition comprises a positive acting, lithographic diazo type composition such as the diazo oxides, including aromatic or heterocyclic esters or amides of napthoquinone diazide sulfonic or carboxylic acids, in admixture with a negative acting diazo type monomer, and a compatible colorant. The monomer releases an acid in exposed areas to effect bleaching.
