Patent ID: 8067145

Claim:
A method for producing a lithography printing plate comprising: curing an image recording layer of a lithography printing plate precursor at an exposed part via image-wise exposure, the image recording layer comprising a polymerization initiator, a polymerizable compound and a hydrophobic binder and being provided on a support, said image recording layer further being provided with a protective layer thereon; and developing by an aqueous solution having pH 2 to 10 and containing at least one of a compound represented by formula (I) and a compound represented by formula (II) as an anionic surfactant, and a modified starch: wherein, in the formulas, R 1 to R 10 each independently represent one of a hydrogen atom and an alkyl group; “l” represents an integer of 1 to 3; and X 1 and X 2 each independently represent one of a sulfonate salt, a sulfate monoester salt, a carboxylate salt and a phosphate salt, provided that the total sum of the carbon atoms in R 1 to R 5 and the total sum of the carbon atoms in R 6 to R 10 , respectively is from 3 to 20 wherein the image-wise exposure is performed by using a laser irradiating a beam of 250 to 420 nm, the exposed lithography printing plate precursor is subjected to heat treatment after the image-wise exposure and prior to the development by the aqueous solution and wherein a rinsing step in water and a step for bringing the precursor into contact with an aqueous solution containing a water-soluble polymer compound are not carried out after the developing.
