Ink of ballpoint pens

Ink raw Materials

■ Oily ink
Dye + solvent + resin is a basic configuration. This is almost the same as the composition of the marker, but the viscosity is different (viscosity of starch syrup and honey position).
■ Water-based ink
Water-based inks are the basic components of pigment + dispersing agent + (viscosity of coffee or tea). Neutral ink is an intermediate viscosity of oily and aqueous, and it can be said that it is tonkatsu sauce or tomato juice. The meaning of neutral is not neutral in comparison with acidic vs. alkaline or oil-to-water, but sticky of ink is located between oil and water. (As it uses water instead of solvent, it belongs to aqueous classification.) ）
