Abstract:
The positive-type planographic printing plate precursor of the invention comprises a support and a recording layer provided on the support, wherein the recording layer contains: a polymer compound having (a) a monomer represented by the following formula (1), (b) a monomer having an aliphatic group having 7 or more carbon atoms and having a bridge bond, and (c) monomer having an acid group as a copolymerization component; and an infrared-ray absorbing agent. The positive-type planographic printing plate precursor of the invention achieves both excellent developability and excellent inking property, as well as better image-forming property and a clear image. wherein in the formula (1), Rf is a substituent containing a fluoroalkyl group or a perfluoroalkyl group having 9 or more fluorine atoms, n represents 1 or 2, and R1 represents hydrogen or a methyl group.
