In a plate or light-sensitive plate for making printing plates comprising a support having an oleophilic surface carrying thereon a photosensitive silver halide emulsion layer, a hydrophilic diffusion transfer image receiving layer containing physical development nuclei, or both an image receiving layer and a photosensitive silver halide emulsion layer formed on the image receiving layer, the press life of a printing plate made from the plate is effectively improved by providing between the support and the lowermost layer a hydrophilic intermediate layer of, e.g., gum arabic, a maleic anhydride-vinyl acetate copolymer or a partially saponified cellulose derivative. |
