Patent ID: 8904930

Claim:
A flexographic printing original plate capable of being laser-engraved which is obtained by subjecting a photosensitive resin composition containing (A) at least one latex having a weight-average degree of gelation of 40% or more, (B) a photopolymerizable component and (C) a photopolymerization initiator to irradiation to light followed by cross-linking and curing, wherein the photopolymerizable component (B) contains a photopolymerizable oligomer and at least one ethylenic unsaturated monomer in 10 to 25% by weight and 5 to 40% by weight respectively, to the weight of the photosensitive resin composition and the at least one ethylenic unsaturated monomer comprises 75 to 5% by weight of a monofunctional monomer and 25 to 95% by weight of a trifunctional monomer.
