Problems solved by technology

The ink-absorbing layer of the printing photo paper is an alumina material containing a pigment particle size below 150 nanometers. When the particle size of the nano-alumina is large, the gloss of the coating is not enough. How to use does not make a reasonable explanation, so it lacks operability
[0006] Chinese patent CN1558025 discloses "manufacturing method of high-gloss color inkjet photo paper", but this patent does not elaborate deeply on the ink receiving layer

Abstract

Photo-stage high brightness water-proof color ink-jet printing paper includes a basic material and a coat coated on it characterizing that said coat contains nm modified Al2O modified by a strong anode ion dispersing agent and a bonder, since the coat contains modified Al2O with the diameter of 30-80nm and inorganic silicon sol with the diameter smaller than 20nm, the invented paper can either absorb water ink or make the ink not to disperse.

Description

technical field [0001] The invention relates to the technical field of color ink-jet printing paper, more specifically, to a photo-grade high-gloss waterproof color ink-jet printing paper. Background technique [0002] After more than 20 years of hard work by Chinese people, China's printing consumables have become an important part of global printing consumables. With the rapid development of the IT industry, digital cameras, and inkjet printers in society, the downstream supporting materials—color inkjet printing Paper follows closely behind, becoming a product with fast-growing market demand and huge profits, and it is increasing at a rate of more than 25% per year. [0003] Photo-grade high-gloss waterproof color inkjet printing paper worldwide is basically monopolized by multinational companies such as Epson, Kodak, HP, Fuji, etc. However, with the upgrading of products, domestic manufacturers also produce such products, but most manufacturers High-gloss color inkjet p...
