PROBLEM TO BE SOLVED: To provide a photosensitive resin composition which can give a printing plate achieving both of image reproducibility and flexibility and having excellent ink receiving property and reusability in printing.SOLUTION: The photosensitive resin composition comprises a water-soluble polymer or a water-swellable polymer (A), an ethylenically unsaturated compound (B), and a photopolymerization initiator (C). The ethylenically unsaturated compound (B) includes a compound (b) having a polyethylene glycol skeleton, only one ethylenically unsaturated bond in the molecule, and a weight average molecular weight of 400 to 800. The composition contains the component (B) by 20 to 65 parts by weight with respect to 100 parts by weight of the component (A), and has a content of the component (b) of 20 to 50 wt.% in the component (B). |
