POSITIVE-WORKING LITHOGRAPHIC PRINTING PLATE PRECURSOR FOR INFRARED LASER AND PROCESS FOR MAKING LITHOGRAPHIC PRINTING PLATE

Japanese Patent JP2011186139

A

To provide a positive-working lithographic printing plate precursor for infrared laser, the precursor having excellent development latitude, dissolution discrimination and plate wear and having little post-exposure degradation in developability over time, and to provide a process for making a lithographic printing plate employing the positive-working lithographic printing plate precursor for infrared laser.

The positive-working lithographic printing plate precursor for infrared laser is configured by layering sequentially above a support: a lower layer containing a water-insoluble and alkali soluble resin and an IR ray absorbent; and an upper layer containing a grafted copolymer having a sulfone amide group, active imide group and/or amide group, wherein the grafted copolymer is a polyurethane resin having as a graft chain an ethylenically unsaturated monomer-derived constitutional unit. The process for making a lithographic printing plate is carried out by using the positive-working lithographic printing plate precursor for infrared laser.
