LASER ENGRAVABLE FLEXOGRAPHIC PRINTING ORIGINAL PLATE

Title:

LASER ENGRAVABLE FLEXOGRAPHIC PRINTING ORIGINAL PLATE

Document Type and Number:

WIPO Patent Application WO/2021/140895

Kind Code:

A1

Abstract:

The present invention suppresses the increase of time required for curing of the entire plate surface of a laser engravable flexographic printing original plate, while achieving the benefits from the decrease of plate surface adhesiveness due to blending of a silicone compound. A laser engravable flexographic printing original plate which is obtained by crosslinking and curing an molded article of a photosensitive resin composition by means of light irradiation, wherein: the photosensitive resin composition contains a water-dispersed latex, a photopolymerizable unsaturated compound, a photopolymerization initiator and a silicone compound having an amino group in each molecule; the silicone compound has a refractive index of from 1.44 to 1.60 in cases where the water-dispersed latex is selected from among polybutadiene rubbers and polynitrile butadiene rubbers; and the silicone compound has a refractive index of from 1.47 to 1.63 in cases where the water-dispersed latex is a polystyrene butadiene rubber.
