PROBLEM TO BE SOLVED: To provide a photosensitive printing plate material which allows writing of data by a small-sized and inexpensive exposing light source of high sensitivity and for which the adoption of a simple plate making not requiring a washing stage is possible. SOLUTION: This photosensitive printing plate material 10 is constituted to include a first base 11, a second base 14 and a photosensitive layer formed between this first base 11 and the second base 14. At this time, the photosensitive layer 13 consists of a photosetting compsn. having the max. curing sensitivity in a visible light region of at least a wavelength >=600 nm or an IR region. |
