    Abstract: A negative image-recording material which can be imagewise exposed to IR radiation from IR lasers and ensures direct image formation from digital data of a computer or the like. The material, when used in a lithographic printing plate, ensures good hardenability in an. image area and exhibits good printing durability, even if not heated for image formation, and ensures a large number of good prints from the printing plate. The recording material contains (A) an IR absorber, (B) a radical generator having an onium salt structure, (C) a radical-polymerizing compound, and (D) a reducing additive, and this is imagewise exposed to IR radiation for image formation. Preferably, the reducing additive (D) is highly reactive with radicals and a reaction product with a radical has high reductivity. Preferred examples of the reducing additive are ether-type hydrogen donors, alcohol-type hydrogen donors, vinyl ethers and phosphine-type compounds.

    IPC: B41C1/10

    Abstract: Disclosed is a presensitized plate composed of a support having thereon an image recording layer which includes: an infrared absorber (A) that is a cyanine dye having at least one fused ring composed of a nitrogen-containing heterocycle in combination with an aromatic ring or a second heterocycle, and having on the aromatic ring or second heterocycle an electron-withdrawing group or a heavy atom-containing group, a radical generator (B), and a radical-polymerizable compound (C), and which is removable with printing ink and/or dampening water. The presensitized of the present invention can be imaged with an infrared light-emitting laser to directly record an image from digital data on a computer or the like and is then subjected to on-machine development without carrying out a development step, which is capable of providing a large number of good impressions with a practical amount of energy.
