Abstract
The invention provides a planographic printing plate precursor having at least: a support; and an image recording layer that is provided on the support, the image recording layer comprising: an infrared ray absorbing agent (A); a polymerization initiator (B); a polymerizable compound (C); and a compound (D) represented by the following Formula (I).In Formula (I), at least one of R1 to R3 represents —(CH2CH2O)n—R4, while the remainder of R1 to R3 respectively independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or R5—COOH; R4 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; n represents an integer of 1 to 20; and R5 represents an alkylene group having 1 to 6 carbon atoms. The invention further provides a printing method using the planographic printing plate precursor and performing on-press development.
