preparation example Construction

[0059]The preparation method of the coating solution for the oxygen barrier layer can be as follows: dissolve the flexible adhesive with oxygen barrier effect and the water-soluble resin containing amine groups in water, slowly add the aqueous solution of the water-based flexible resin containing carboxyl groups under stirring, and finally add Surfactant, stirring, to obtain an oxygen barrier layer coating solution; or, the flexible adhesive with oxygen barrier effect and the water-based carboxyl group-containing flexible resin are dissolved in water, and under stirring, slowly add the water-soluble resin containing amine group Aqueous solution, finally add surfactant, stir to obtain oxygen barrier layer coating liquid.

[0060] Water is used as a solvent, and when the oxygen barrier layer is formed after coating on the photoreceptor, the water is evaporated.

[0061] The surfactant here is a leveling agent, and the leveling agent is a commonly used leveling agent for the oxyg...

Abstract

The invention provides an oxygen barrier layer and a self-flat-topped lattice point digital flexible resin plate containing the oxygen barrier layer, wherein the surface of a convex part of the self-flat-topped lattice point digital flexible resin plate is sanded. The oxygen barrier layer contains particles with the size of 0.01-10 microns; the particles in the oxygen barrier layer are formed by reacting amido-containing water-soluble resin and carboxyl-containing polymer resin in water, that is, the particles are directly formed in the oxygen barrier layer coating liquid, the process of dispersing solid particles is omitted, and the purpose that the particles are contained in the oxygen barrier layer is achieved. The oxygen barrier layer coating liquid is coated on the photosensitive elastomer, namely the ultraviolet polymerization relief printing plate forming layer, the surface of the sand mesh has higher printing ink transfer capability, the ink layer of the printed matter is thicker, and the color rendition is more vivid.

Description

technical field [0001] The invention relates to a flexographic printing plate that can be digitally imaged, in particular to an oxygen barrier layer and a self-flat top dot digitized flexible resin plate whose surface is grained on a raised portion. This application belongs to the green printing materials of the sub-direction 3.19 Eco-environmental materials under the key direction of 3.1 New functional material industry in the 3 New Material Industry of the Strategic Emerging Industry Catalog. Background technique [0002] Digitally imageable flexographic printing plates are basically known. It comprises at least one dimensionally stable support film, a photopolymerizable elastomeric layer and a digitally imageable layer. Examples of digitally imageable layers are laser ablatable layers, inkjet printer writeable layers, or thermal imaging layers, where laser ablatable layers are currently popular in the digital flexographic market. [0003] The laser ablatable layer, also...
