PURPOSE:To obtain a photosensitive planographic printing plate excellent in developability and stain resistance, having high sensitivity and excellent also in plate wear. CONSTITUTION:A photosensitive layer contg. a photocrosslinkable polymer having a maleimido group in each side chain, a sensitizer, diazo resin and a polymer having at least one group represented by the formula (where R<1> is H or methyl) is formed on a substrate having a hydrophilic surface to obtain the objective photosensitive plano-graphic printing plate. |
