Abstract

The invention relates to a blue ink and concretely to a water pigment blue ink which is easy to wash and can be used in fountain pen and sign pen. The said ink solves the problem in present blue ink which is of poor water resistance and sun resistance and can not be washed easily. The weight ratio of raw materials composition of the prepared ink is: 1.0 % -5 % of Berlin blue colorant, 0.2 % - 5 % of oxalic acid complexing agent, 0.01 % - 2 % of surface activator, 1 % - 10 % of water-loss reducer , 0.1 % - 1 % of binding agent, 0.1 % - 1 % of preservative agent, and the other is water. In relation to the present technology, the significance effect of this invention is: 1. in relation to the present blue ink, it has good water resistance and sun resistance but small diffusibleness; 2. in relation to the present writing ink of all kinds, it is erasable which solves the problem that clothes can not be washed cleanly when contaminated by the present ink; 3. the said ink and its catabolite is nontoxic, flavourless and can not pollute the environment.

Description

technical field [0001] The invention relates to a blue ink, in particular to an easy-to-clean water-based pigment-type blue ink suitable for fountain pens and marking pens. Background technique [0002] At present, there are four main types of writing inks in daily use in China: blue-black ink, pure blue ink, black ink and carbon ink. Both pure blue ink and black ink are dye-based inks, which are usually blended with two or more dyes. The disadvantage of this type of ink is that it has poor water resistance, and the handwriting is easily infiltrated by water, alcohol and other solvents and spreads; the light fastness is poor. , Under the action of light, the association molecules of the dye chromophore are easy to depolymerize, which makes the handwriting fade, so it is not suitable for writing files and other materials. The water resistance and light fastness of ordinary blue-black ink are also poor; the water resistance and light fastness of carbon ink are better, but onl...
