Abstract

The invention provides a gel ink comprising low-carbon alcohol. The gel ink comprises the components of, by weight, 4-21% of low-carbon alcohol, 2-3% of a thickening agent, 30-50% of a color paste comprising 4-6% of a water-soluble pigment, 10-15% of a surfactant, 5-20% of a moisturizing lubricant, 0.05- 0.1% of a preservative fungicides, 0.2-0.8% of a PH value adjusting agent, and 30-40% of deionized water. According to the invention, low-carbon alcohol is reasonably added, and the ratio of the components is optimized, such that the prepared gel ink has good rheological property and greatly improved writing performance.

Description

technical field [0001] The invention relates to a neutral ink, in particular to a neutral ink containing a lower alcohol. Background technique [0002] Gel pens are favored by consumers at home and abroad because of their smooth writing, clear handwriting, water resistance, light resistance and long shelf life. Neutral ink ballpoint pens have been favored by consumers since their inception due to their smooth and smooth writing, bright and quick-drying, non-bleeding paper, long cap-off time, and stable chemical properties. At present, neutral ink ballpoint pens have replaced water-based oily ballpoint pens as the mainstream of ballpoint pens. 4 of the world's 5 pens are produced in China, but high-end inks mainly rely on imports, which hinders my country's progress from a big pen-making country to a strong pen-making country. [0003] progress. [0004] For example, CN02104934.3, the invention patent titled "A Neutral Ink", discloses a neutral ink. The viscosity modifier...
