Photosensitive resin composition for flexographic printing and flexographic printing plate

Provided is a photosensitive resin composition for flexographic printing comprising at least (A) a hydrophilic copolymer, (B) an elastomer, (C) a polymerizable unsaturated monomer, and (D) a photopolymerization initiator, wherein the surface area SA of a phase comprising the hydrophilic copolymer (A) accounts for 15-60% of the cross section of the cured resin composition, and a phase having a surface area of 3 [mu]m2 or greater but less than 100 [mu]m2 accounts for at least 20% of the surface area of the phase comprising the hydrophilic copolymer (A). 种柔性印刷用感光性树脂组合物，其至少含有(A)亲水性共聚物、(B)弹性体、(C)聚合性不饱和单体和(D)光聚合引发材料，在该树脂组合物的固化物的截面中，包含亲水性共聚物(A)的相面积S为15％以上且60％以下，包含亲水性共聚物(A)的相中、相面积为3μm以上且低于100μm的相所占的比率为20(面积％)以上。
