Abstract

The invention discloses the digital writing ink and the preparing method, the component percentage by weight is: pigment 5-15%, pigment dispersant 2-5%,adjuvant 6-16%, penetrant 0.4-1.3%, pH modifier 0.5-1.8%, ultraviolet absorbent 0.3-0.9%, bactericidal agent 0.3-1.5%, carboxymethyl cellulose 0.005-0.1%, polyvinyl pyrrolidon 1-7%, non-ionic surface active agent 0.6-1.8%; and the residual is water. The digital writing ink is characterized by the natural and bright colour, good stability, strong staining power, the cleaning function to the injector, and the insoluble granule size is much smaller than the injector size and the injectionis smooth; the printed picture and character is indiffusible, incurable, resistant to ultraviolet radiation, fastness; the product is suitable for kinds of color printer and can be filled in endless form, which saving the stock and decreasing the print cost.

Description

technical field [0001] The invention relates to a stationery product, in particular to a spray-painting ink, and also to a production method thereof. Background technique [0002] With the development of society, various color inkjet printers have been widely used in digital printing, photo printing, etc. Some of the existing inkjet inks are dark in color, easy to fade, poor in stability, easy to spread pictures, easy to wrinkle paper, Moreover, the nozzles are easy to block and cannot be refilled, and some have a strong smell, which will cause certain harm to the human body, and different models are equipped with original ink from the manufacturer, and the price is relatively high. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned shortcoming and provide a kind of natural and bright color, good stability, strong tinting strength, can make nozzle have self-cleaning function, cheap, safe and environment-friendly digital pr...
