Title:
FLEXOGRAPHIC PRINTING PLATE PRECURSOR
Document Type and Number:
Japanese Patent JP2023100692
Kind Code:
A
Abstract:
To provide a flexographic printing plate precursor which makes it possible to precisely reproduce a microcell pattern on the surface of a printing plate without a special device or an additional step, and thus to improve the ink laydown on a solid-printed part.SOLUTION: A flexographic printing plate precursor comprises 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 mass%.SELECTED DRAWING: None
