    Abstract: A method of making a planographic printing plate includes exposing, to infrared light, a planographic printing plate precursor including a recording layer provided on a substrate, and developing the precursor using an aqueous alkaline solution. The recording layer comprises a copolymer containing a structural unit derived from (meth)acrylonitrile and at structural unit derived from styrene, a water-insoluble and alkali-soluble resin, and an infrared absorbing agent, the solubility of the recording layer in the aqueous alkaline solution being increased by the exposure. The aqueous alkaline solution has a pH of 8.5 to 10.8 and contains a betaine-based amphoteric surfactant and an ammonium salt represented by Formula (I): R1, R2, R3, and R4 each independently represent an alkyl or aryl group; the total number of carbon atoms in R1, R2, R3, and R4 is not more than 20; and X− represents a counter anion.
