Description

Highly environment-friendly oil pen ink

Technical Field

The invention belongs to the field of ink, and particularly relates to highly environment-friendly ink for an oil pen.

Background

Ink pens can be classified into water-based pens, medium-sized pens, and oil-based pens according to the properties of the ink used. The ink used by the water-based pen is pure water, mainly takes water as a solvent, does not contain volatile toxic organic solvents, has no adverse effect on the health of operators in the using process, has no pollution to the atmospheric environment, and has no pollution to the drawn works.

However, the ink still has some effective components which are chemically synthesized, for example, the dye can be synthesized by selecting a synthetic dye, the binder can be water-soluble resin, and the like, so that certain potential safety hazard is brought. Particularly for children with relatively weak body resistance, the ink is easy to be wiped on skin and clothes due to careless operation when the ink is used for drawing, and is not easy to wash; even some children can taste the ink with bright color and luster by mouth due to interest, and the harm of the ink to human bodies is more serious.
