Title:
PLANOGRAPHIC PRINTING PLATE PRECURSOR, PLANOGRAPHIC PRINTING PLATE MANUFACTURING METHOD, AND PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/048451
Kind Code:
A1
Abstract:
An objective of the present invention is to provide an on-press development type planographic printing plate precursor which suppresses color development failure after time has elapsed, and which has excellent visibility. Another objective of the present invention is to provide a planographic printing plate manufacturing method and a printing method. A planographic printing plate precursor of the present invention is an on-press development type planographic printing plate precursor including a supporting body and an image recording layer, wherein: the supporting body includes an aluminum alloy plate and an anodic oxidation coating disposed on the aluminum alloy plate; a density of intermetallic compounds having a major diameter of 2.0 μm or more on a surface of the supporting body on the opposite side to the image recording layer is at most equal to 1,000 pieces/mm2; the image recording layer includes an infrared absorber and an acid color forming agent; and a color development coefficient of the acid color forming agent, obtained by means of a prescribed measuring method, is at least equal to 20,000.
