Abstract

The invention discloses a colorless ink capable of realizing color development in the air, and a preparation method thereof. The colorless ink is composed of a reactive dye, a fading agent, a pH conditioning agent, a surfactant, a thickening agent, an antifreeze agent, a defoaming agent, and distilled water. The formula is simple, and the preparation method is simple. The colorless ink can be injected into a children painting pen provided with a valve, wherein the pen holder and the pen core of the children painting pen are transparent and colorless, the colorless ink is colorless in the pen holder, after wiring on paper, automatic color development is realized via contact with the air. The colorless ink is functional, interesting, and is friendly to the environment, and is an ideal educational toy for children.

Description

technical field [0001] The invention relates to ink, in particular to a colorless ink capable of developing color in air and a preparation method thereof. Background technique [0002] At present, most of the inks used in children's writing pens sold in the market are colored. Although they also have the advantages of safety and environmental protection, smooth writing, bright color, and clear writing, they are not significantly different from the inks of adult writing pens on the whole, and it is difficult to attract children. It is not easy to stimulate their interest in learning and exploring. Therefore, it is necessary to develop a colorless ink that can automatically develop color in the air that integrates functionality, intelligence, interest, knowledge and environmental protection, and is used for children's writing and painting. Contents of the invention [0003] The object of the present invention is to provide a colorless ink capable of developing color in the ...
