    Abstract: A lithographic printing process which comprises the steps of: imagewise exposing to infrared light a presensitized lithographic plate which comprises a hydrophilic support and a removable image-forming layer containing an infrared absorbing agent having the absorption maximum within an infrared region and a dye precursor having substantially no absorption within a visible region to change the dye precursor to a visible dye having an absorption within a visible region within the exposed area, and to make the image-forming layer irremovable within the exposed area; removing the image-forming layer within the unexposed area of the lithographic plate mounted on a cylinder of a printing press; and then printing an image with the lithographic plate mounted on the cylinder of the printing press. The other processes are also disclosed.

    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.
