Ink-receptive layer coating solution for high-glossiness water-resistant photographic paper and preparation method thereof

Abstract

The invention discloses an ink-receptive layer coating solution for high-glossiness water-resistant photographic paper. The ink-receptive layer coating solution is composed of the following components in parts by weight: 50-70 parts of water, 3-7 parts of color fixative, 0.1-0.5 part of defoaming agent, 0.1-0.5 part of whitener, 5-10 parts of polyvinyl alcohol solution (15%), 12-18 parts of microporous silicon dioxide and 10-15 parts of polymer emulsion. The preparation method comprises the following steps: respectively adding the color fixative, defoaming agent, whitener and polyvinyl alcohol solution into the water according to the formula technique proportion, stirring uniformly, adding the silicon dioxide, stirring at high speed for 30-90 minutes, adding a polymer emulsion, stirring at high speed for 20-60 minutes, and filtering to form the ink-receptive layer coating solution for high-glossiness water-resistant photographic paper. The ink-receptive layer coating solution adopts the microporous silicon dioxide as the ink-receptive medium, thereby enhancing the ink-receptive drying rate and printing resolution of the product.

Description

technical field [0001] The technical field of the present invention is the technical field of new materials, and the application field is the field of image output, in particular to an ink-absorbing layer coating solution of high-gloss water-resistant photographic paper and a preparation method thereof. Background technique [0002] In September 2012, my country Lucky Film Group, a giant film manufacturer in China, closed the last color film production line in Nanjing, marking that my country's digital inkjet printing technology has basically replaced the traditional silver salt output technology in the image output industry. [0003] Inkjet printing photo paper is the printing medium material in digital inkjet printing technology, which is made by coating the coating liquid on the surface of the substrate. At present, the types of photo paper on the market mainly include coated paper photo paper and cast-coated photo paper. Among them, the coated paper photo paper is coated...

AI Technical Summary

Problems solved by technology

[0004] Coated paper photo paper has the advantages of good water resistance, high flatness, complete hydrophobicity on the back of the paper, vivid and bright output colors, and is suitable for long-term storage. However, its surface gloss is relatively low, the printing drying speed is slow, and the surface is prone to scratches And leave fingerprints, which will affect the printing color display and preservation

[0005] Cast-coated photo paper has high gloss, fast printing and drying speed, high surface hardness, and vivid and bright colors. However, because it uses paper as the base material, it has relatively poor water resistance and is easy to curl, which affects long-term storage applications.
