PHOTOSENSITIVE RESIN COMPOSITION

摘要

Provided are a photosensitive resin composition having an anionic group and a cationic group, which is characterized in that it has an anionic group content of 0.15 mole/kg or more and a cationic group content of 0.15 mole/kg or more and contains a cationic group-having polymer having a number average molecular weight of 1000 or more, and also a printing plate material to be produced by applying the composition onto a support. The composition has excellent developability with water, and this gives a flexographic printing plate having excellent durability in printing in aqueous ink and having excellent image reproducibility in flexography.
