Example Embodiment

[0025] Embodiment 1 is that the formula of neutral black ink is component (weight gram):

[0026] 6.0 grams of pigment carbon black, 2.0 grams of radiant blue oar, 5.1 grams of dispersant MEE, 6.0 grams of fatty alcohol polyvinyl ether sulfate triethanolamine, 4.5 grams of water-soluble resin styrene polyacrylic resin, solvent 1, 2 propylene glycol 5 grams, B 5 grams of glycol, 5 grams of glycerol monomethyl ether, 4.0 grams of thickener polyvinylpyrrolidone (PVP), 1.0 grams of PVC, 0.1 grams of modified polydimethylsiloxane as a leveling agent, and 5.0 grams of ethanolamine as a neutralizer Preservative Casson-880.1g, defoamer SPA-102 and rust inhibitor benzotriazole each 0.1g, deionized water 56.3g;

Example Embodiment

[0027] Embodiment 2 is that the formula of neutral blue ink is component (weight gram):

[0028] Pigment phthalocyanine blue 7.2 grams, permanent violet 1.0 grams, dispersant Tween 4.0 grams, secondary alcohol ether succinate sodium sulfonate 3.2 grams, water-soluble resin styrene polyacrylic resin 3.2 grams, solvent 1, 2 propylene glycol 5 grams , 5 grams of ethylene glycol, 4 grams of glycerin, 0.5 grams of thickener hydroxyethyl cellulose (HEC), 0.8 grams of hydroxypropyl cellulose (HPC), 0.1 grams of flow agent modified polydimethylsiloxane , 10 grams of neutralizing agent triethanolamine, 0.1 grams of preservative Casone-880, 0.1 grams of antifoaming agent SPA-102 and 0.1 grams of antirust agent benzotriazole, 55.3 grams of deionized water.

[0029] According to the component weight ratio of the above formula, the following method is used to prepare neutral ink, a, prepare ink precursor, a kind of pigment, dispersant, water-soluble resin, solvent are made into ink precursor before entering high-shear emulsifier , which is a microemulsion pigment paste; b, the ink thickener is made into a water-soluble fluid; c, the ink precursor (pigment paste) and the water-soluble fluid are sheared in an emulsifier to make it Form a kind of oil-in-water emulsion, its preparation step is to process and form a kind of oil-in-water emulsion in high-shear emulsifier, the oil-in-water emulsion and a kind of thickener related to pH value, alkali, pigment, Dispersant, ionized water are blended to form a neutral ink composition; d, in the emulsion of a high-shear emulsifier, leveling agents, defoamers, preservatives, and rust inhibitors need to be added to further mix to form a PH Value-related neutral emulsion inks.
