RESIN FOR PRINTING PLATE MATERIAL, AND PLANOGRAPHIC PRINTING PLATE MATERIAL USING THE SAME

摘要

Disclosed is a planographic printing plate material which has scratch resistance to a level available to mass production in a large size and has excellent sensitivity to a developing solution having a low pH value or a fatigue developing solution having a low activity and an excellent development latitude. Also disclosed is a resin for use in the planographic printing plate material, which has a residue of a heterocyclic compound having a bicyclic fused hetero ring therein, wherein the bicyclic fused hetero ring has two or more C=O or NH groups in one ring.
