Embodiment 1～ Embodiment 25 and comparative example 1～ comparative example 3

[0678]

[0679] The lithographic printing plate precursors of Examples 1 to 25 and Comparative Examples 1 to 3 were prepared by the following methods.

[0680] Coat the undercoat layer coating liquid of the above-mentioned composition on the above-mentioned support so that the dry coating amount becomes 20 mg / m 2 , forming an undercoat. Each image recording layer coating solution described in Table 1 to Table 3 was bar-coated on the undercoat layer, and dried at 120° C. for 40 seconds to form a dry coating weight of 1.0 g / m 2 image recording layer.

[0681] As for the image-recording layer coating liquid, it is prepared by mixing and stirring polymer particles before coating.

[0682] If necessary, the protective layer coating solution of the above composition was bar-coated on the image recording layer, and baked at 120° C. for 60 seconds to form a protective layer.

[0683] In the column of the protective layer in Tables 1 to 3, "none" is described when no protective la...

Abstract

The invention provides an on-machine developing type lithographic printing plate precursor, a method for manufacturing a lithographic printing plate using the on-machine developing type lithographic printing plate precursor, and a lithographic printing method using the on-machine developing type lithographic printing plate precursor. The on-press developing lithographic printing plate precursor has a support, an image recording layer and an overcoat layer orderly, the image recording layer contains a binder polymer having a structural unit formed of an aromatic vinyl compound and a structuralunit formed of an acrylonitrile compound, and the on-machine developing type lithographic printing plate precursor satisfies a specific mode.

Description

technical field [0001] The invention relates to an on-machine development type lithographic printing plate original plate, a production method of the 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-receiving portion) by utilizing the property that water and oily ink repel each other. ), a difference in the adhesion of the ink occurs on the surface of the lithographic printing plate, and after the ink is applied only to the image portion, the ink is transferred to a printed object such as paper for printing.
