摘要：
The present disclosure describes a printing original plate capable of being laser-engraved such that printing deficiency caused by residues is avoided, and such that resolution and printing quality are good.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) photopolymerizable compound and (C) photopolymerization initiator to irradiation to light followed by cross-linking and curing. The photopolymerizable component (B) contains the photopolymerizable oligomer and the 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 ethylenic unsaturated monomer comprises 75 to 5% by weight of monofunctional monomer and 25 to 95% by weight of trifunctional monomer.
