Photosensitive resin composition.

摘要

A photosensitive resin composition comprising compo- jents A, Band C described below is provided. The composition of the present invention is quite effectively usable for the preparation of photosensitive resin printing plates having excel- ent water developability, image reproducibility and printabil- ty. The composition comprises:
