<p>The present invention provides a planographic printing plate precursor in which a photosensitive layer and a protective layer are successively laminated on a surface of an aluminum support exhibiting hydrophilicity, wherein the protective layer contains a binder polymer, and a copolymer of ethylene oxide and propylene oxide. The planographic printing precursor can be written with an infrared laser, and can improve productivity in plate-making work.</p> |
