Problems solved by technology

[0002] Since the advent of inkjet printing photo technology, the photo paper for inkjet printing has been produced by the traditional casting coating method. When using the traditional casting coating technology to produce high-gloss photo paper, the casting coating machine can only be produced at a slow speed due to the limitation of the casting coating method. In addition, during the production process, part of the wastewater with paint is discharged, the production efficiency is low, the production cost is high, and the wastewater discharge also poses a burden on environmental protection
[0003] CN103129202B (2014-4-16) discloses a kind of polyvinyl alcohol image photographic paper, yet the performance of this photographic paper still needs to be improved

Embodiment 1

[0056] 1. When preparing the primer coating, add light calcium carbonate at a ratio of 25% to 75% deionized water to start the dispersing machine. During the dispersion process, add 0.6% polycarboxylate sodium salt dispersant, and then add in order after dispersing for 20 minutes. Add 6% polyvinyl acetate emulsion adhesive, 8% polyvinyl alcohol glue, and 0.3% color fixing agent Y. After adding all of them, continue stirring for 15 minutes to complete the preparation.

[0057] 2. The preparation of the top coating is to use water-based silica sol as the main body, add 12% of polyvinyl alcohol glue with a solid content of 10%, and 0.2% of color-fixing agent Y, stir well and set aside.

[0058] 3. Preparation of back-coating paint Add 3% polyvinyl alcohol to 95% deionized water, stir and disperse fully, then turn on steam and heat to gelatinize under continuous stirring state, heat gelatinization time for 30 minutes, the colloid is colorless and transparent. OK, cool to room temp...

Abstract

The invention relates to a paper and especially relates to a transfer coating ink-jet printing high-gloss photographic paper. The paper comprises a surface coating, a base coating, a raw paper layer and a back coating. The surface coating is an ink absorption water-resistant gloss coating. The base coating is an ink absorption fixation coating. The back coating is a water-resistant coating for balancing two surface tensions of a photographic paper. The base coating comprises light calcium carbonate, a sodium polycarboxylate dispersant, a polyvinyl acetate emulsion adhesive, a polyvinyl alcohol glue solution and a fixer. The surface coating comprises aqueous silica sol and a polyvinyl alcohol glue solution. The back coating comprises polyvinyl alcohol. The photographic paper surface is a high-gloss mirror surface, images obtained by color ink-jet printing have plump colors and realizes real restoration and ink absorption and fixing performances are good.
