Title:

ON-MACHINE DEVELOPMENT TYPE LITHOGRAPHIC PRINTING PLATE PRECURSOR, METHOD FOR PRODUCING LITHOGRAPHIC PRINTING PLATE, AND LITHOGRAPHIC PRINTING METHOD

Document Type and Number:

WIPO Patent Application WO/2024/071344

Kind Code:

A1

Abstract:

This on-machine development type lithographic printing plate precursor comprises a support body and an image recording layer disposed on the support body. The image recording layer contains an electron-accepting polymerization initiator, an electron-donating polymerization initiator, an infrared light absorber, and a salt compound A. The HOMO value of the anion constituting the salt of the salt compound A is -6.2eV - -4.4 eV. This method for producing a lithographic printing plate or this lithographic printing method uses the on-machine development type lithographic printing plate precursor.
