Abstract
Disclosed is a photosensitive flexographic resin plate having excellent wear resistance and giving relief image faithful to a negative film. The photosensitive flexographic printing plate is composed of a base plate and a photosensitive resin layer thereon wherein said photosensitive resin layer is formed from a resin composition comprising a resin having rubber elasticity, an unsaturated monomer, a photopolymerization initiator and resin particles having an average particle size of about 0.01 to 6 micron, and when said photosensitive resin layer is cured, the cured layer has a JIS A hardness of 30.degree. to 80.degree. and an impact resilience of at least 20%.
