Color ink-jet printing paper picture-layer paint

Abstract

The invention discloses color ink-jet printing paper picture-layer paint. Paper not special for color ink-jet printing has the well-known disadvantages that the ink absorbency is not appropriate, ink is easy to seep, spread and diffuse, the ink droplet is large and bad in circularity, and an image is rough, does not have hierarchy sense, is low in density, bad in sharpness, not resistant to water and slow in drying speed, and the like. Color ink-jet printing paper is a deeply-processed product of paper, is prepared by performing special coating processing on the surface of common printing paper, and is capable of adsorbing aqueous ink without diffusing the ink droplet to the periphery, thereby completely keeping original colors and sharpness. The novel color ink-jet printing paper picture-layer paint is low in price and excellent in quality.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coating for color spraying. Background technique [0002] At present, there are more and more varieties and models of color inkjet printing paper on the market, but so far, most of the color inkjet paper sold in China is imported from abroad, and the price is expensive. For example, Epson office color inkjet paper A4.1440dpi, 100 sheets per pack, the market retail price is as high as 90 yuan, which greatly increases the burden on users. For domestic color spray paper products, the main raw materials (such as coating paint, coated base paper) are still required, and the research and development level is relatively backward, the production quality is relatively low, and there is no unified technical standard. The relatively low price has indeed attracted some high-end users, but when it comes to quality, it can only be described as "good and bad". What's more, ordinary copy paper is used...

Problems solved by technology

[0002] At present, there are more and more types and models of color inkjet printing paper on the market. However, so far, most of the color inkjet paper sold in China is imported from abroad, and the price is expensive.

For example, Epson office color inkjet paper A4.1440dpi, 100 sheets per pack, the market retail price is as high as 90 yuan, which greatly increases the burden on users

For domestic color spray paper products, the main raw materials (such as coating paint, coated base paper) are still required, and the research and development level is relatively backward, the production quality is relatively low, and there is no unified technical standard

The relatively low price has indeed attracted some high-end users, but when it comes to quality, it can only be described as "good and bad", and some even use ordinary copy paper as color spray paper to deceive consumers.

Generally speaking, the domestic brands of color inkjet paper mainly have the following disadvantages: ink is easy to spread during printing, large ink droplets, poor roundness, rough image, no layering, low density, poor clarity, not water resistant, slow drying speed, etc. shortcoming

The reason is that, on the one hand, it is due to the monopoly of foreign technology and market;
