Embodiment

[0753] Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited to this. In addition, in this Example, "%" and "part" represent "mass%" and "mass part", respectively, unless otherwise specified. In addition, in polymer compounds, unless otherwise specified, the molecular weight is the weight average molecular weight (Mw), and the ratio of the structural repeating unit is the molar percentage. In addition, the weight average molecular weight (Mw) is the value measured as the polystyrene conversion value by the gel permeation chromatography (GPC) method.

Abstract

A lithographic printing plate original plate having an image-recording layer on a support body, wherein the image-recording layer contains an infrared absorbent represented by formula 1-1, a polymerization initiator and a polymerizable compound. The description specifies the details of R<1>, R<11>-R<18>, n<11>-n<14>, L, Za, A1 and A<2> in formulas 1-1 and 2.

Description

technical field [0001] The invention relates to a lithographic printing plate original plate, a method for making a lithographic printing plate and a lithographic printing method. Background technique [0002] In general, a lithographic printing plate consists of an oleophilic image portion that receives ink during printing and a hydrophilic non-image portion that receives fountain solution. Lithographic printing is a method in which the lipophilic image portion of a lithographic printing plate is used as an ink-receiving portion, and the hydrophilic non-image portion is used as a fountain solution-receiving portion (ink non-accepting portion) by utilizing the mutual repulsion of water and oil-based ink, A difference in ink adhesion is caused on the surface of a lithographic printing plate to allow ink to adhere only to an image portion, and then the ink is transferred to a printed material such as paper to perform printing. [0003] In order to prepare such a lithographic ...
