Problems solved by technology

However, the grinding time of pigment inks is long and the process is complicated; most pigment inks will leave color materials on the surface; printing on flat paper such as glossy paper cannot print glossy images; and pigment inks are easy to separate layer, precipitation, and unstable storage; pigment colorants have incomplete color spectrum, the color is not bright enough, and the transparency is not good; the manufacturing cost of pigment ink is higher, and the price is more expensive than dye ink, and the price difference is as high as two to four times.

Abstract

The invention relates to jet ink which comprises the following components in percentage by weight: 0.2-12 percent of weather-resistant dye, 1-13 percent of modified polyurethane resin emulsion (solid content), 5-25 percent of humectant, 5-15 percent of penetrant, 0.1-3 percent of ultraviolet light absorber, 0-2 percent of surface tension regulator, 0-2 percent of pH regulator, 0.01-0.5 percent of fungicide and the balance of deionized water. The jet ink is characterized in that the service life of the water-based resin dye jet ink product can be greatly prolonged. The jet ink is good in storage stability and smooth to print. The jet ink has the advantages of waterproofness, chemical resistance, high-temperature and low-temperature resistance, abrasion resistance, ageing resistance, high brightness, color transparency and excellent reducibility with an excellent application prospect.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a dye inkjet ink and a preparation method thereof. Background technique [0002] Common water-based dye inkjet inks are completely dissolved inks at the molecular level. This ink is a complete composite solution. The probability of clogging the ink head during inkjet printing is very small. After inkjet printing, it is easy to be absorbed by the material. Bright, clear layers and lower price than pigment-based inks, so now water-based dye inks are mainly used for indoor documents, pictures and digital textile printing that do not need to be stored for a long time; such as printing pictures, making color-jet business cards, etc. However, its disadvantage is that it is not resistant to water and chemical reagents, and because the dye molecules are quickly decomposed under ultraviolet radiation, it will obviously fade within one month after being used outdoors, which affect...
