Abstract:
The present invention provides a planographic printing plate precursor including a support and a positive recording layer formed on the support and containing: (A) a polymer having a structural unit represented by the following general formula (1), (B) a photo-thermal converting agent, and (C) an amino compound having a methylol group or an alkoxymethyl group; and a positive recording layer whose solubility in an alkaline developer is improved by exposure to light or by heating. In general formula (1), R1 represents an alkyl group or a cyclic group, x represents 0 or 1, and A represents a bivalent bonding group. According to the invention, a positive planographic printing plate precursor for use with infrared lasers having excellent chemical resistance and wide image development latitude can be obtained.
