Embodiment 1

[0031] This embodiment provides a kind of dye ink compatible with the original inkjet pigment ink, and the formula system is selected: diethylene glycol (i.e. diethylene glycol), the weight percentage is 5%; ethylene glycol, the weight percentage is 5%; diethylene glycol Monobutyl ether, the percentage by weight is 3%; Toynol superwet-320, the percentage by weight is 0.1%; the bestech SF-black 100MK color paste of Shanghai Beitong color, the percentage by weight is 20%; the rest is deionized water. The viscosity of the system ink sample was measured to be 1.60 (mpa.s, 30±1°C), and the surface tension was 27.0 (mN / m).

[0032] The preparation of above-mentioned dye ink is as follows:

[0033] (1) Measure each component according to the formula ratio and place it in the same container;

[0034] (2) Stir and mix with a magnetic stirrer or a mechanical stirrer, and the stirring speed is 90-900 rpm;

[0035] (3) The stirring time is 20-60 minutes;

[0036] (4) Filter through a f...

Embodiment 2

[0040] This embodiment provides a dye ink compatible with the original inkjet pigment ink. The preparation process is the same as that of Embodiment 1, and the formula system is selected: diethylene glycol, 6% by weight; ethylene glycol, 5% by weight; diethylene glycol Alcohol monobutyl ether, 3% by weight; dynol 604 of Evonik, 0.15% by weight; Alpha-jet black SP02Liq. of Celludye, 25% by weight; the rest is deionized water. It is measured that the viscosity of the system ink sample is 1.75 (mpa.s, 30±1°C), and the surface tension is 25.5 (mN / m).

Embodiment 3

[0044]This embodiment provides a dye ink compatible with the original inkjet pigment ink. The preparation process is the same as that of Embodiment 1, and the formula system is selected: diethylene glycol, 7% by weight; ethylene glycol, 6% by weight; diethylene glycol Alcohol monobutyl ether, the percentage by weight is 3%; Evonik's dynol 604, the percentage by weight is 0.1%; the bestech SF-black100MK color paste of Shanghai Beitong Color, the percentage by weight is 20%; the rest is deionized water. The viscosity of the system ink sample was measured to be 1.90 (mpa.s, 30±1°C), and the surface tension was 27.0 (mN / m).

Abstract

The invention discloses a dye ink compatible with an original inkjet pigment ink, which comprises the following components in percentage by mass: 10-35% of a pigment, a solvent, a cosolvent, 0.05-0.3%of an auxiliary agent and water, wherein the mass sum of the solvent and the cosolvent is 10%-40%, the solvent is a monohydric alcohol or a dihydric alcohol, the cosolvent is an alcohol ether solvent, and the auxiliary agent is an alkynediol ethoxy compound. The added cosolvent and auxiliary agent have a certain synergistic effect, and after the ink is mixed with the original inkjet pigment ink under the condition that the smoothness of the ink in the successive printing process is ensured, the incompatibility (such as white exposure, ink shortage, fuzzy handwriting, nozzle blockage, no ink discharge and the like during printing) does not occur, so that the printing quality is improved. The problem that an ink-jet printer using pigment ink is incompatible after dye ink is replaced is solved.

Description

technical field [0001] The invention relates to an inkjet dye ink, in particular to a dye ink compatible with the original inkjet pigment ink. Background technique [0002] The colorants of dye inks are all natural or synthetic, and their development process is mature. The dye colorant exists in the ink as a single molecule. This structure makes the dye ink not easy to clog the nozzle; and the pigment ink is different. The colorant is used as a colorant by repeatedly grinding minerals. The selected raw materials are limited, and the process also has many defects. The colorant is a solid particle insoluble in water. It can only rely on the effect of an emulsifier to wrap a layer of resin component outside the colorant. With the help of the hydrophilic group on the resin component Agglomerates to emulsify colorants and suspend them in solvents and water. For general users, pigment inks are expensive to use, and they prefer cheap and easy-to-use dye inks. However, the origin...
