    Abstract: A negative image-recording material for heat-mode exposure, which is able to form images by heat-mode exposure, comprises (A) a polyurethane resin having at least one or more side-chain branches of the following general formulae (1) to (3) which polyurethane resin is soluble in an alkaline aqueous solution, (B) a photo-thermal converting agent, and (C) a compound capable of generating a radical through heat-mode exposure to light of a wavelength which can be absorbed by the photo-thermal converting agent. In formulae (1) to (3), R1 to R11 each independently represents a monovalent organic group; X and Y each independently represents an oxygen atom, a sulfur atom, or —N(R12)—; Z represents an oxygen atom, a sulfur atom, —N(R13)—, or an optionally-substituted phenylene group; R12 represents a hydrogen atom or a monovalent organic group; and R13 represents a hydrogen atom or a monovalent organic group.

    Abstract: A method for manufacturing a lithographic printing plate precursor includes the steps of providing a support as a web, coating an image recording layer on the front side of the support, and depositing a back layer on the back side of the support using a deposition technique which is capable of depositing the back layer according to a predefined image. The method enables stacking and recutting of lithographic printing plate precursors without the need for interleafs.

    Abstract: A process for making a lithographic printing plate that includes in sequence an exposure step of imagewise exposing by means of an infrared laser a lithographic printing plate precursor that has provided above a support a positive-working recording layer including (Component A) a (meth)acrylonitrile-derived monomer unit- and styrene-derived monomer unit-containing copolymer, (Component B) a water-insoluble and alkali-soluble resin, and (Component C) an infrared absorbing agent and a development step of developing, using an aqueous alkali solution including a betaine-based surfactant or a nonionic surfactant, the aqueous alkali solution having a pH of 8.5 to 10.8, by removing an exposed area of the positive-working recording layer whose solubility in aqueous alkali solution has been increased by the exposure. There is also provided a lithographic printing plate made by the process for making a lithographic printing plate.
