Abstract

The invention relates to composite color ink and a preparation method thereof, belongs to the field of stationery and printing, and can solve the problem that the existing color ink has few kinds andis difficult to clean, and the composite color ink includes a color fluoran dye, a color developer, a thickener, a surfactant, a preservative, a dispersant and water. The composite color ink is non-toxic, non-corrosive and free of irritating odors, has simple preparation process and rich source of raw materials, can be discolored in the case of alkaline substances, can realize repeated use of writing paper, and has good economic benefits and society benefits. The composite color ink is highly functional and is a good stationery and printing product.

Description

technical field [0001] The invention belongs to the field of stationery and printing, and in particular relates to a colored ink and a preparation method thereof. Background technique [0002] At present, the inks used by people are not limited to traditional black inks, and the demand for colored inks is increasing, so the demand for color pigments is also increasing, and the existing color pigments are increasingly unable to satisfy people. and market demand. At this stage, most of the color inks directly use the color dyes of the base color as colorants, so there are very few color types of color inks. Moreover, the existing colored ink has a slow drying speed, and it is not easy to clean if it sticks on a desk or clothes during writing. Contents of the invention [0003] Aiming at the problems that the existing color inks have few types and are not easy to clean, the invention provides a composite color ink and a preparation method thereof. [0004] The present inve...
