PROBLEM TO BE SOLVED: To provide a lithographic printing material using a silver complex salt diffusion transfer process in which formaldehyde is not used while preventing printing durability, inking property and printing contamination resistance from being deteriorated or while improving them. SOLUTION: The lithographic printing material applying the silver complex salt diffusion transfer process has at least a silver halide emulsion layer and a physical development nucleus layer on a support, wherein a water-soluble polymer containing a specific functional group is contained in at least one layer of the lithographic printing material, and the lithographic printing material contains at least one compound selected from a compound containing two vinylsulfonyl groups and one or more carbamoyl groups, a compound containing two vinylsulfonyl groups and one or more aromatic rings, and a compound containing three or more vinylsulfonyl groups.
