ABSTRACT:
The present invention provides a water developable flexographic printing plate for water-developing with a slip layer having excellent properties. The printing plate comprises a substrate, a photosensitive resin composition layer formed on the substrate, a slip layer formed on the photosensitive resin composition layer, and a cover film formed on the slip layer, wherein the slip layer is composed of hydroxyalkyl methyl cellulose, the cover film is a matted film containing silica, and an adhesive strength between the slip layer and the photosensitive resin composition layer is at least 20 g/50 mm higher than that between the cover film and the slip layer.
