Title:
NEGATIVE LITHOGRAPHIC PRINTING ORIGINAL PLATE AND METHOD FOR MAKING LITHOGRAPHIC PRINTING PLATE
Document Type and Number:
WIPO Patent Application WO/2019/039074
Kind Code:
A1
Abstract:
Provided is a negative lithographic printing original plate which has an image recording layer disposed on an aluminum support, wherein the image recording layer contains polymer particles 1 having a constituent unit comprising a monomer having a solubility parameter of at least 23 MPa1/2, thermoplastic polymer particles 2, and an infrared absorbing agent. It is possible to form an image when fusion and/or aggregation of the thermoplastic polymer particles 2 occur because of the heat generated during lithographic exposure. Also provided is a method for making a lithographic printing plate using said negative lithographic printing original plate.
