PURPOSE:To obtain a photosensitive lithographic plate reducing a residue film in a non-image area after development, preventing a stain at the time of printing, and having both a difficult-to-stain property at the time of printing and a superior property against plate wear. CONSTITUTION:On a surface of a substrate that is grained and anodized, a hydrophilic layer composed of at least one compound selected out of inorganic or organic acid salts of compounds having at least one amino group and group selected out of phosphone group, phosphine group, and phosphate group is provided, or the surface is subjected to another specific surface treatment. After that, a photosensitive layer is provided on the surface of the substrate. In this manner, a photosensitive lithographic plate is produced. |
