Abstract: There is provided a lithographic plate material which can be desensitized by distilled water or a fountain solution used for other lithographic plates, without desensitizing using an etching solution, and with less scumming in non-image portions of the print. The lithographic plate material has an image-receptive layer formed on a support and containing polyvinyl alcohol cross-linked by tetra alkoxy silane hydroxylate, titanium oxide microparticles, and silica having an average particle size of 1 nm to 100 nm. The image-receptive layer has a surface with an arithmetic mean roughness of not less than 0.40 &mgr;m and less than 1.20 &mgr;m, a contact angle of less than 50 degrees with distilled water at room temperature, and ink-receptiveness for hot-melt and lipophilic ink.
