<P>PROBLEM TO BE SOLVED: To provide a photosensitive lithographic printing plate material which has high sensitivity, ensures little sensitivity variation due to environmental humidity even upon development at low pH (pH 3.0-9.0), excels in inking property of an image portion of a print in an early stage of printing and in stain suppressing property of a non-image portion, and excels also in printing durability, and a method for preparing the same. <P>SOLUTION: The photosensitive lithographic printing plate material includes on a support a photosensitive layer containing a sensitizing dye, a polymerizable ethylenic double bond-containing compound, a polymerization initiator and a binder, wherein the photosensitive layer contains a sensitizing dye represented by general formula (1) as the sensitizing dye. <P>COPYRIGHT: (C)2010,JPO&INPIT |
