Abstract

PURPOSE:To obtain a photosensitive planographic printing plate having high sensitivity and superior resistance to processing chemicals by forming a photosensitive layer of a specified photosensitive compsn. on a support based on an electrolytically etched and anodically oxidized Al material. CONSTITUTION:A photosensitive layer of a photosensitive compsn. contg. o- naphthoquinonediazidosulfonic ester of polycondensation resin consisting of polyhydric phenol and aldehyde or ketone, >=50wt.% novolak resin and <=50wt.% vinyl-based polymer having phenolic hydroxyl groups is formed on a support based on an electrolytically etched and anodically oxidized Al material. The etching is carried out in an electrolytic soln. contg. principally hydrochloric acid or nitric acid. A photosensitive planographic printing plate having high sensitivity and improved resistance to processing chemicals is obtd.
