Problems solved by technology

[0004] However, due to the use of a large number of colorants, resins, solvents and various organic additives to enhance the writing effect in conventional inks, there are still defects that cannot be ignored in the light resistance and oxidation resistance of water-based inks.
In the natural preservation state, this kind of ink is easy to deteriorate when it is exposed to light for a long time or under high temperature for a long time; after the ink is used, the handwriting formed is also easy to fade under strong light or in a humid and corrosive environment, making the handwriting gradually fade. Lost the role of recording information
[0005] Chinese patent authorization announcement number CN103788757B discloses the application of a natural lotus shell pigment in the field of food packaging and printing ink preparation. The application of lotus shell pigment in printing ink improves the light resistance of the ink and can slow down the fading of the ink under light. However, this kind of pigment has poor dispersibility in water-based writing ink, which will affect the writing fluency of water-based ink, so it is difficult to directly apply it in water-based writing ink
Patent authorization announcement number CN1292813B discloses a water-based magenta ink composition and its inkjet recording method. A special disulfonic acid derivative or its salts are used in this type of ink composition, thereby improving the ink quality. Lightfastness and color fastness, but this component is mainly used in spray compositions. When it is applied to general writing ink, it cannot show outstanding anti-oxidation performance, and it will also affect the writing performance and chemical stability of the ink. influences

Abstract

The invention relates to the technical field of ink processing, and particularly relates to a light-fast and oxidation-resistant ink composition for a writing pen. The ink composition is prepared fromthe following components: a coloring agent, a bright pigment, water-soluble resin, thermoplastic polyurethane resin, dextran, fucoidan, polycarbodiimide, an organic solvent, a stabilizer, a corrosioninhibitor, a lubricant, a preservative and water, wherein the organic solvent is a mixture formed by compounding propylene glycol, diethylene glycol and isopropanol according to a mass ratio of 1 to1 to 5; the lubricant is glycerol or polyether modified silicone oil; and the preservative is a mixture of mannan and propyl p-hydroxybenzoate according to an equal mass ratio. The ink composition hasthe advantages of being good in writing performance, high in stability, outstanding light-fast and oxidation-resistant performance and little possibility of color fading.

Description

technical field [0001] The invention relates to the technical field of ink processing, in particular to a light-resistant and anti-oxidation ink composition for writing pens. Background technique [0002] Ink is a coloring substance used for writing, which can leave color traces on the surface of the substrate, so as to achieve the purpose of recording information, and has greatly promoted the development of civilization. Western quill pens and Eastern brush pens are used They are all inks. The inks used in the early days are generally composed of water and pigments. The pigments include various carbon blacks, mineral pigments, etc. The color rendering effect of this ink is better, but the adhesion is poor and the oxidation resistance is insufficient. Therefore, The handwriting on copybooks, documents and other cultural relics handed down from ancient times gradually oxidized and fell off with the passage of time, and most of the handwriting is very unclear. [0003] In rou...
