A polymerizable composition comprises binder polymer having carboxylic repeating unit (I), infrared absorbent, polymerization initiator and polymerizable compound. Polymerizable composition comprises binder polymer having repeating unit of formula (I), infrared absorbent, polymerization initiator and polymerizable compound. [Image] R 1>H or methyl; R 2>linking group having at least 2 atoms selected from C, H, O, N and S with a total of 2-82 atoms; A : O or -NR 3>-; R 3>H or monovalent hydrocarbon having 1-10C; and n : 1-5. An independent claim is also included for a planographic printing plate precursor comprising support having photosensitive layer that contains the polymerizable composition. |
