Abstract

The invention discloses a coating layer of high-gloss waterproof colorful ink-jet printing paper. The coating layer is characterized in that an ink coating layer with high absorbility is coated on manufacturing type wood pulp paper and mainly comprises nano aluminium hydrosilicate, a cationic dispersant and an adhesive and also comprises a water repellent agent, ultrafine aluminium hydrosilicate, wherein the weight ratio of the ultrafine aluminium hydrosilicate to the cationic dispersant to the adhesive is 100:(1-3):(5-15); the coating layer also comprises a defoaming agent, a flatting agent, a thickening agent, a whitening agent and a humidifying agent. By the mode, the coating layer can quickly absorb water-based ink, is high in gloss and high in color fixing capacity and can achieve an effect of silver salt picture quality.

Description

technical field [0001] The invention relates to the coating field of printing paper, in particular to a coating of high-gloss waterproof color inkjet printing paper Background technique [0002] Compared with other digital color printing technologies, color inkjet printing technology has the advantages of easy large-format output, ink output according to image needs, relatively low ink cost, high image resolution, and vivid color reproduction. It occupies an extremely important position in the field of digital color printing. [0003] Inkjet printing requires a recording material coated with an ink-receiving layer in order to exhibit good image resolution and color reproduction. Especially for water-based inkjet printing inks, it is also required that the receiving layer has fast absorption and color fixing capabilities, so that the printed image is quick-drying and waterproof. [0004] Chinese patent CN1814913 is a photo-grade high-gloss waterproof color inkjet printing p...
