Beschreibung
Zusammenfassung: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, in a cross-section of a cured product of the resin composition, a phase area of a phase comprising the hydrophilic copolymer (A), SA, is 15% or more and 60% or less, and a proportion of the phase having a phase area of 3 μm2 or more and less than 100 μm2 is 20 (% by area) or more of the phase comprising the hydrophilic copolymer (A).
