Embodiment 1

[0063] Preparation of magenta ink

[0064] Formulation composition (weight percent)

[0065] Red solvent dye raw material (C.I. solvent red 49) 0.5%, toluene 15%, polyoxyethylene ether nonionic surfactant ET-135 10%, glycerol 1%, AMP-95 0.1%, n-propanol 35% , preservatives such as phenol 0.1%, deionized water 38.3%.

[0066] Preparation:

[0067] Mix the red solvent dye and toluene at room temperature, and disperse for 10 minutes on a high-speed dispersing homogenizer (Shanghai Beierte Electromechanical Equipment Technology Co., Ltd.) to obtain a mixed solution;

[0068] Mix ET-135, glycerol, AMP-95, n-propanol, preservatives, and deionized water at room temperature, and stir at high speed for 1 hour to obtain a mixed solution;

[0069] The above two mixed solutions were mixed and stirred at high speed for 1.5 hours, homogenized for 10 minutes, and filtered with a 0.2 micron filter membrane to remove impurities to obtain the final product.

Embodiment 2

[0071] Preparation of yellow ink

[0072] Formulation composition (weight percent)

[0073] Yellow solvent dye raw material (C.I. Solvent Yellow 88) 1%, xylene 5%, surfactant (ET-135) 5%, propylene glycol 6%, AMP-955%, n-propanol 16%, preservative benzoic acid 2% , 60% deionized water.

[0074] The preparation method is the same as in Example 1.

[0075] The specific structure includes long-chain fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty acid polyoxyethylene ester, fatty amine polyoxyethylene ether, fatty acyl alkanolamine, fatty acyl alkanolamine polyoxyethylene ether, castor Sesame oil ethylene oxide adduct, etc.

Embodiment 3

[0077] Preparation of cyan ink

[0078] Formulation composition (weight percent)

[0079] Cyan solvent dye raw material (C.I. solvent blue 70) 3%, cyclohexanone 31%, surfactant (ET-135) 1%, ethylene glycol 10%, diethanolamine 2%, n-propanol 20%, isopropanol 7%, preservative sodium benzoate 1%, deionized water 25%.

[0080] The preparation method is the same as in Example 1.

Abstract

The invention relates to a microbead latex ink and a preparation method thereof. The microbead latex ink is characterized by comprising the following components with the weight percent: (1) 0.5 percent to 5 percent of solvent dye, (2) 1 percent to 10 percent of surface active agent, (3) 5 percent to 35 percent of organic solvent, (4) 10 percent to 40 percent of auxiliary agent, and (5) 25 percent to 60 percent of deionized water. The prepared ink is not only suitable for special ink-jet printing media, but also is suitable for uncoated media, such as coated paper, and the like, has even grain size distribution and good disperse stability, can be stored for a long period, has quick printing and drying speed and has high edge sharpness.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a microbead emulsion ink suitable for inkjet printing and a preparation method thereof. The ink prepared by the method is especially suitable for inkjet printing on uncoated media such as coated paper Print. Background technique [0002] With the integration of inkjet printing and printing, more and more people pay attention to inkjet printing of uncoated media such as coated paper. Coated paper is smooth and smooth, with high smoothness and good gloss. Compared with special inkjet printing paper, coated paper is cheaper, which can greatly reduce the cost of color inkjet printing paper. Coated paper has good compatibility with most color laser printers, but it is not suitable for color inkjet printers. Printing coated paper with an inkjet printer will cause scattered ink, ink flow, and ink accumulation. The main reason is that the amount of ink ejected by the inkjet pr...
