Abstract

Provided is a lithographic printing plate precursor that has a support body and an image recording layer disposed on the support body. The image recording layer contains organic particles including an additive polymerization-type resin that has a structural unit A having a hydrogen bond-donating site. The content of the structural unit A in the additive polymerization-type resin is more than 20 mass% with respect to the total mass of the additive polymerization-type resin. Also provided is a method for manufacturing a lithographic printing plate that uses said lithographic printing plate precursor.

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 ...
