Abstract
Disclosed is a photosensitive resin composition for flexographic printing plates containing a thermoplastic elastomer (A), a polymer (B) mainly composed of butadiene, a photopolymerizable unsaturated monomer (C) and a photopolymerization initiator (D) (which composition substantially contains no hydrophilic polymers). In this photosensitive resin composition for flexographic printing plates, the number average molecular weight of the polymer (B) is not less than 10,000 and not more than 60,000, and the 1, 2 vinyl content in the total double bonds of the polymer (B) is not more than 25%.
