PROBLEM TO BE SOLVED: To provide a photosensitive resin composition allowing production of a flexographic printing plate having high impact resilience and high notch/crack resistance.SOLUTION: The liquid photosensitive resin composition for a flexographic printing plate contains 100 pts.mass of a polyurethane prepolymer (a) with an ethylenically unsaturated group, 10 to 150 pts.mass of an ethylenically unsaturated compound (b), and 0.01 to 10 pts.mass of a photoinitiator (c) and contains 5 to 100 pts.mass of a compound expressed by general formula (1) CH=CH-CO-O-(CHO)-H, as the ethylenically unsaturated compound (b), relative to 100 pts.mass of the polyurethane prepolymer (a) with the ethylenically unsaturated group. In the general formula (1), n represents an integer in a range of 1 to 20. |
