Problems solved by technology

[0004] These three methods have their own advantages and disadvantages. The first method is convenient and easy to implement, but it only slightly improves the ozone resistance and has no particularly obvious effect.
The second method is to improve the ozone resistance, but the process is more complicated. After the image is printed, it is necessary to apply the coating process or print the general transparent resin ink to protect the dye.

Abstract

The invention relates to ink-jet aqueous dye-based ink capable of improving fastness to ozone on microporous photographic paper. The ink-jet aqueous dye-based ink is characterized in that the fastness of the aqueous dye-based ink to the ozone on microporous photographic paper is improved by means of mixing special pigment with the nano-particle size with dye, and a series of experiments finds that the fastness of the dye-based ink to the ozone can be obviously improved by the method. A formula system of the ink includes the dye with the weight percent ranging from 2% to 5%, the special pigment with the weight percent ranging from 0.5% to 3%, humectant with the weight percent ranging from 5% to 40%, viscosity regulator with the weight percent ranging from 1% to 10%, fungicide with the weight percent ranging from 0% to 1%, chelator with the weight percent ranging from 0% to 1%, buffering agent with the weight percent ranging from 0% to 1%, from 0 to 5% of surfactant and the balance deionized water. The ink-jet aqueous dye-based water has the advantages that the fastness of the aqueous dye-based ink to the ozone on a microporous medium can be obviously improved, influence on the glossiness of the dye-based ink on the media is low, and excellent printing smoothness, printing stability, restarting performance after a machine is stopped and storage stability are realized.

Description

technical field [0001] The invention relates to a water-based dye ink, in particular to a water-based dye ink with high ozone fastness on microporous photo paper. Background technique [0002] Water-based dye ink is printed on microporous photo paper, if it is not covered with a film or sealed with glass, it is prone to discoloration or fading in the natural environment. The natural environment mentioned here includes outdoor and indoor environments. The factors causing fading in the outdoor environment include light and gas, while the fading in the indoor environment is mainly caused by gases, especially ozone. On microporous photo paper, cyan fading is more typical. In the field of inkjet, cyan inks basically use two dyes, direct blue 199 and acid blue 9, especially direct blue 199. This dye has poor ozone fastness on microporous photo paper. [0003] Many technicians in the inkjet industry have studied how to improve the ozone resistance of cyan dye ink on microporous m...
