Imaging element and method for making a lithographic printing plate according to silver salt diffusion transfer processing

摘要

The present invention provides an imaging element for making a lithographic printing plate according to silver salt diffusion transfer processing, said imaging element comprising on a support a silver halide emulsion layer and a receiving layer, said receiving layer comprising (i) physical development nuclei, (ii) an inorganic colloidal substance and (iii) a hydrophilic polymer being a homo- or copolymer of acrylamide or methacrylamide.
