Problems solved by technology

The recording material is less waterproof due to the hydrophilic gelatin contained in the cover layer
[0005] Such an inkjet recording sheet is disclosed in Chinese patent CN1393346. The recording sheet is coated with an ink receiving layer and a glossiness adjustment layer on the substrate. The ink receiving layer contains organic acid metal salts and cationic color fixing agents to improve light resistance and Ozone resistance, but no description of gloss and post-print drying speed
[0006] Chinese patent CN1388008 discloses an inkjet recording material, which is two or more layers of ink-receiving layers on a waterproof carrier and a back coating mainly containing organic polymers, wherein the receiving layer contains 3 to 30 primary particles Nano, and adding fine particles with an average particle size of 1-5 microns and an average particle size of 5-20 microns to improve the transportability. Because of the addition of large particles of fine particles on the surface, it is easy to cause surface gloss reduction and cracking
[0007] Chinese patent CN1348868 discloses a recording medium and an imaging method using it. The recording medium is coated with two ink-absorbing layers on a substrate having a barium sulfate layer. The ink-absorbing layer contains aluminum-based pigments, and the ratio of the upper-layer aluminum-based pigments is The surface area is larger than the underlying layer, the patent does not describe the gloss and drying speed after printing

Abstract

The invention relates to an ink jet printing medium, especially relating to a waterproof strong-light ink jet printing medium, which includes supporter and ink-absorbing layer, and its characteristic: the ink-absorbing layer contains inorganic pigment and adhesive at particle size 8-15 nanometer and specific surface area 150-200 sq m / g, and it can both absorb dye ink and both pigment ink, and has high glossiness surface, and after printing, it dries rapidly, waterproof, and anti-blotting.

Description

technical field [0001] The invention relates to an ink-jet printing medium, in particular to a waterproof high-gloss ink-jet printing medium. technical background [0002] In recent years, due to the overall development of electronic technology, the storage capacity of digital images has gradually increased, and the color printing images have also increased, and the technology of color printing images has also developed rapidly. [0003] Inkjet printing technology has been gradually popularized and expanded in the field of color image printing in recent years due to its characteristics such as easy colorization, low noise, no pollution, and low price. With the improvement of inkjet technology, the ink droplets of inkjet printers are getting smaller and higher, and the resolution is getting higher and higher. The quality of printed images is gradually approaching the level of silver salt photos. In order to improve efficiency, the printing speed is getting faster and faster. ...
