PROBLEM TO BE SOLVED: To provide an alkali developable photosensitive resin composition capable of obtaining a printing plate material excellent in image persistence and printing durability according to the present invention. The present invention is a photosensitive resin composition comprising an ethylenically unsaturated compound, an alkali-soluble resin, a near-infrared absorbing dye, a halomethyl group-containing compound, and an organic boron anion-containing compound, The alkali-soluble resin has a carboxylic acid group in the side chain, and a part of the carboxylic acid group is introduced with an ethylenically unsaturated group by reacting with an epoxy group-containing ethylenically unsaturated group compound. , The organoboron anion-containing compound is represented by a specific chemical formula (a), and the weight ratio of the ethylenically unsaturated compound to the alkali-soluble resin is 40:60 to 90:10. The present invention relates to a photosensitive resin composition. [Selection figure] None |
