ABSTRACT:
Disclosed is a lithographic printing plate material which provides a printing plate which causes no peeling of film even after printing of a large number of prints and even with use of special printing ink such as ultraviolet-curing ink. This printing plate material comprises a polyester film subjected to hydrophilization treatment by coating with an organic copolymer as a support and at least one undercoat layer, at least one emulsion layer containing a silver halide, and an image receiving layer containing physical development nuclei provided on the support in this order, characterized in that the lowermost undercoat layer contiguous to the support contains a bisphenol type epoxy resin latex.
