Abstract: PROBLEM TO BE SOLVED: To provide a lithographic printing plate precursor which excels in printing durability and chemical resistance and suppresses ablation in exposure. SOLUTION: The lithographic printing plate precursor has on a support a positive recording layer containing (A) a polymer containing copolymerized components derived from (a) a monomer represented by general formula (1), (b) a monomer selected from methyl methacrylate, methyl acrylate, ethyl methacrylate and ethyl acrylate, and (c) a monomer selected from acrylic acid, methacrylic acid and vinylbenzoic acid, and (B) a compound which absorbs light and generates heat, wherein the positive recording layer increases solubility in an alkali developer upon exposure or heating. In the general formula (1), R 1 represents a hydrogen atom or a methyl group; R 2 and R 3 represent a hydrogen atom, an aliphatic group or an aromatic group; X represents -C(CH 3 ) 2 -, -CH(CH 3 )- or -(CH 2 ) n -; Y represents -NH- or -O-; and n represents an integer of 0-10.

Abstract: PROBLEM TO BE SOLVED: To provide a laminate of lithographic printing plate precursors which is obtained by laminating infrared-sensitive lithographic printing plate precursors without using a slip sheet, and which supresses scratching of a recording layer, prevents void generation in the recording layer due to batch cutting and excels in suitability to batch cutting, and to provide a method for producing lithographic printing plate precursors using the laminate of lithographic printing plate precursors. SOLUTION: The laminate of lithographic printing plate precursors is obtained by laminating a plurality of lithographic printing plate precursors each having a recording layer containing a water-insoluble and alkali-soluble resin and an infrared absorbent and capable of forming an image upon irradiation with infrared radiation on one surface of a support, and a plurality of linear organic polymer layers arranged apart from each other in a width direction on a surface of the support opposite to the surface having the recording layer, in such a way that the recording layer and organic polymer layers adjacent to the recording layer are brought into direct contact with each other. The method for producing lithographic printing plate precursors using the laminate of lithographic printing plate precursors is also provided. COPYRIGHT: (C)2008,JPO&INPIT
