Beschreibung
Zusammenfassung:	The present invention provides a flexographic printing plate precursor which makes it possible to precisely reproduce the pattern of a microcell on the surface of a printing plate without requiring the use of any specialized device or any additional step, and thus to improve the ink laydown on a solid-printed part. A flexographic printing plate precursor comprising at least a support (A), a photosensitive resin layer (B), an oxygen barrier layer (C) and a heat-sensitive mask layer (D) which are laminated in this order, wherein a photosensitive resin composition constituting the photosensitive resin layer (B) comprises (a) a polymer prepared by polymerizing a conjugated diene, (b) an ethylenically unsaturated compound and (c) a photopolymerization initiator, and wherein the content of the photopolymerization initiator (c) in the photosensitive resin composition is 2 to 9% by mass.
