Document Type and Number:
WIPO Patent Application WO/2020/022071
Kind Code:
A1
Abstract:
A method for producing a lithographic printing plate comprises a step of exposing a lithographic printing original plate that includes an image-recording layer on a support, and a step of carrying out a development process using a developing solution having a pH of at least 10 but less than 12. The image-recording layer contains a binder having a constituent unit represented by formula (Bn), a photopolymerization initiator, and a polymerizable compound. The developing solution contains an amphoteric surfactant and a non-amphoteric surfactant. In formula (Bn), R1 to R3 each independently represent a hydrogen atom or an alkyl group; R4 to R8 each independently represent a hydrogen atom or a monovalent substituent; and L1 represents a divalent linking group.
