LITHOGRAPHIC PRINTING PLATE PRECURSOR, METHOD OF PREPARING LITHOGRAPHIC PRINTING PLATE, AND LITHOGRAPHIC PRINTING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18185902 titled 'LITHOGRAPHIC PRINTING PLATE PRECURSOR, METHOD OF PREPARING LITHOGRAPHIC PRINTING PLATE, AND LITHOGRAPHIC PRINTING METHOD

Simplified Explanation

The patent application describes a lithographic printing plate precursor, a method of preparing a lithographic printing plate, and a lithographic printing method.

  • The lithographic printing plate precursor consists of a support and an image-recording layer.
  • The image-recording layer contains various components including an onium polymerization initiator, a borate compound, an infrared absorber, a chromogenic agent, and a compound A.
  • Compound A is an onium salt formed of a cation with a lower shape index than the cationic moiety of the onium polymerization initiator.
  • The method of preparing a lithographic printing plate involves using the lithographic printing plate precursor.
  • The lithographic printing method utilizes the prepared lithographic printing plate.


Original Abstract Submitted

Provided are: a lithographic printing plate precursor having a support and an image-recording layer on the support, in which the image-recording layer contains an onium polymerization initiator, a borate compound, an infrared absorber, a chromogenic agent, and a compound A which is an onium salt formed of a cation having a shape index lower than a shape index of a cationic moiety of the onium polymerization initiator; a method of preparing a lithographic printing plate using the lithographic printing plate precursor; and a lithographic printing method.
