The invention discloses a photosensitive elastomer composition with excellent ink affinity. The photosensitive elastomer composition comprises (A) a thermoplastic elastomer; (B) a liquid polyolefin plasticizer; (C) liquid polybutadiene of which the tail end is grafted with a hydrophilic group; (D) a monomer containing at least one unsaturated double bond functional group; (E) a photoinitiator or aphotoinitiation system; (F) auxiliaries. According to the flexographic resin plate containing the photosensitive elastomer composition having excellent ink affinity, the polymer liquid polybutadienecontaining hydrophilic groups is introduced into a photosensitive elastomer, so that the flexographic resin plate has excellent ink affinity; and the flexographic printing ink on an ink transfer roller is more easily accepted when the embossment image-text part using the flexographic resin plate is printed, so that the purpose of improving the quality of printed products is achieved.
