Water-based nano coating-free yellow pigment ink

Abstract

The invention discloses a water-based nano coating-free yellow pigment ink which is composed of the following components by the weight percentage: 20-30% of yellow nano color paste, 2%-8% of diethylene glycol, 2%-8% of glycerol, 5%-10% of an antioxidant, 8%-12% of a quick drying agent, 10%-14% of glue, 2%-8% of a cross-linking agent, 1%-4% of an adhesion promoter, and the balance being water. Thecolor printed by the pigment ink provided by the invention is bright and full, a coating layer does not need to be added, and the pigment ink is soluble in water. In addition, the color printed by thepigment ink provided by the invention also has metallic luster, and the pigment ink with the metallic luster effect is initiated in the world. According to the invention, the requirements of the market on high-end water-based pigment ink are solved, and imported high-end ink is completely replaced. The problems that when other pigment ink on the market is applied to related picture products, thecolor is dark, and roughness is achieved are effectively solved. The pigment ink can be blended with corresponding concentration, and can be used as writing tool ink. The ink is combined with paper and permeates into a paper core, and the ink can be permanently used indoors without fade.

Description

technical field [0001] The invention belongs to the technical field of water-based pigment inks, in particular to water-based nanometer uncoated yellow pigment inks. Background technique [0002] Water-based inks are divided into water-based dye inks and water-based pigment inks according to their color properties. The advantage of the dye-based ink is that the dye is dissolved in water, and the ink of the writing pen is smooth, easy to manufacture, and low in cost. The disadvantage is that the ink is not water-resistant and light-resistant. For pigment-based inks, the pigments are highly dispersed in the medium, which overcomes the characteristics of dye-based inks that are not resistant to water and light. However, mechanical sanding of the pigments is required during manufacture, and the manufacturing process requires high requirements. At present, the pigment inks on the market are relatively inferior, and the printed colors are prone to chromatic aberration and poor ad...

The advantage of dye-based ink is that the dye is dissolved in water, and the writing pen produced is smooth, easy to manufacture, and low in cost. The disadvantage is that the ink is not water-resistant and light-resistant

For pigment-based inks, the pigments are highly dispersed in the medium, which overcomes the characteristics of dye-based inks that are not resistant to water and light. However, mechanical sanding of the pigments is required during manufacture, and the manufacturing process requires high requirements.

At present, the pigment inks on the market are relatively inferior, and the printed colors are prone to chromatic aberration and poor adhesion. Small spots will appear due to uneven shrinkage of the ink surface tension, resulting in unsaturated and not bright colors, and special coatings are required. In order to achieve part of the desired effect, and insoluble in water

Based on the influence of these factors, the application of pigment ink is limited
