Producing method of photosensitive planographic printing plate and printing plate produced thereby

摘要

A method for producing a photosensitive planographic printing plate may comprise (i) carrying out electrolysis to an aluminum support in an aqueous solution of hydrochloric acid or nitric acid so as to provide the aluminum support with a roughened surface; (ii) coating a photosensitive composition on the roughed surface of the aluminum support to obtain a photosensitive layer, the photosensitive composition containing: (A) a monomer having an ethylenic double bond which is also polymerizable; (B) a photoinitiator composition containing an iron arene complex compound; and (C) a polymer binder, (iii) drying the photosensitive layer.
