    摘要: A double-sided adhesive flexographic printing plate underlay for use in the manufacture and mounting of flexographic printing plates is provided. The underlay is carrier sheet with a solvent acrylic adhesive stripe-coating provided on both sides thereof. In addition, a siliconized release liner is provided to cover one of the coated sides of the carrier sheet. Both the carrier sheet and the release liner are formed from a glass clear polyethylene terephthalate (PET) and the solvent acrylic adhesive is transparent such that ultraviolent light can readily pass through the underlay. The construction of the underlay is such that it can withstand the washout conditions employed in the manufacture of both liquid and solid photopolymer flexographic printing plates.

    摘要: The present invention aims to provide a flexographic printing original plate which exhibits improved sustainability of the ability of preventing the plate surface from staining. According to the present invention, there is provided a water-developable flexographic printing original plate including at least a support and a photosensitive resin layer provided on the support, in which the photosensitive resin layer contains a water-dispersible latex, a photopolymerizable unsaturated compound, a photopolymerization initiator, and a silicone compound. When the water-dispersible latex is one or more latex rubbers selected from the group consisting of polybutadiene rubber and poly(nitrile-butadiene) rubber, the silicone compound is a silicone compound having an amino group in the molecule and has a refractive index of 1.44 to 1.60. When the water-dispersible latex is poly(styrene-butadiene) rubber, the silicone compound is a silicone compound having an amino group in the molecule and has a refractive index of 1.47 to 1.63.
