Abstract

PURPOSE:An aqueous ink for ball point pens, containing a specific mercaptobenzothiazole derivative, having improved abrasion preventing effect between metallic balls and tips and lubricity, and capable of giving good writing conditions. CONSTITUTION:An aqueous ink prepared by incorporating preferably 0.01-3wt% mercaptobenzothiazole derivative of formulas I and/or II (R is lower alkyl, H or halogen; M is H, NH4 or alkali metal; n is an integer 1-5), e.g. 3-mercaptobenzothiazole or an adduct thereof with 1-5 mole ethylene oxide, with an aqueous ink. EFFECT:Improved abrasion resistance even with tips made from a synthetic resin, e.g. polycarbonate, other than metal, and remarkably extended writing distances with smooth writing conditions.

Alternatively, low viscosity water-based inks are made by adding nonionic surfactants, but these water-based inks lack lubricity and have high friction between the ball and the chip. 1 Synthetic resin or metal chips Abrasion occurs and the ball becomes loose, resulting in blurred handwriting and difficulty in memorizing smoothly.
When writing, abrasion noise occurs between the ball and the tip.

The amount of these water-soluble dyes to be used is preferably 05 to 305 to 30 parts by weight based on the total amount of the ink. This is because if it is less than 0.05% by weight, the ink concentration cannot be achieved, and if it is more than 600 parts by weight, the ink viscosity is too high, which may result in poor ink discharge when filled into a ballpoint pen.
