Problems solved by technology

[0002] At present, most of the inks on the market are oil-based. Oil-based inks have the advantages of bright color, clear lines, and non-diffusion. However, due to the use of organic solvents, and many effective components in the ink are chemically synthesized substances, pollution problems have arisen.
[0003] Especially for children with relatively weak body resistance, when using ink to draw, it is easy to wipe the ink on the skin and clothes due to careless operation, which is not easy to wash off; The mouth tastes the bright ink, which further emphasizes the harm of ink to the human body

Abstract

The invention belongs to the technical field of dye ink and particularly relates to hand-drawing harmless water-based ink based on vegetable dye. The ink adopts a water-solution system, thus, pollution of an organic solvent is solved, and the cost is saved; extracts of natural plants are completely adopted as effective components, synthetic chemicals are not used, and a user can directly touch the ink with hands for drawing without worrying about the harm to the body health.

Description

technical field [0001] The invention belongs to the technical field of dye inks, in particular to a hand-painted harmless water-based ink based on plant dyes. Background technique [0002] At present, most of the inks on the market are oil-based. Oil-based inks have the advantages of bright color, clear lines, and non-diffusion. However, due to the use of organic solvents, and many effective components in the ink are chemically synthesized substances, pollution problems have arisen. . [0003] Especially for children with relatively weak body resistance, when using ink to draw, it is easy to wipe the ink on the skin and clothes due to careless operation, which is not easy to wash off; The mouth tastes the brightly colored ink, which aggravates the harm of ink to the human body. Contents of the invention [0004] The present invention aims at the problems mentioned in the above-mentioned background technology part, and provides a kind of hand-painted harmless water-based ...
