Abstract

PURPOSE:To obtain a water base ink composition which can markedly suppress the wear of the ball socket by the rotating ball and can assure good ink delivery for a long time by adding a specified compound to an ink composition for a ball-point pen essentially consisting of a colorant, a solvent and water. CONSTITUTION:This ink composition is prepared by adding 1-(2,3- dihydroxypropyl)benzotriazole to an ink composition for a ball-point pen essentially consisting of a colorant (e.g. carbon black), a solvent (e.g. ethylene glycol/ glycerol) and water.

2. Description of the Related Art A ballpoint pen, unlike a writing instrument having a fiber nib or a resin nib, has little change in handwriting width due to abrasion of the nib even when used for a long period of time, and a relatively thin handwriting can be obtained. It is often used because it is used. The water-based ink composition used for such a ballpoint pen is mainly composed of a coloring material, a solvent and water, and has a viscosity of 1 to
Some cp (25 ° C) and 50 to 2000 cp (25

In a water-based ink composition for a ball-point pen, the ink composition adhering to the surface of the ball is transferred to a writing surface such as paper as the ball rotates, but an appropriate amount is transferred, and further, to a handwriting. Properties such as appropriate viscosity, surface tension and a high concentration that does not cause bleeding and blurring, and high handwriting with excellent water resistance and light resistance are required.

The problem is that the writing distance becomes shorter. A ballpoint pen using the water-based ink composition is apt to cause ball sinking due to wear of a ball receiving seat due to rotation of the ball. As a result, there is a problem that the ink circulation groove in the ball-point pen tip is blocked by the ball, the ink is not sufficiently ejected, and the handwriting is scratched, smooth writing cannot be performed, and the writing distance is shortened. This problem is particularly remarkable when an aqueous ink composition having a viscosity of 50 to 2000 cp (25 ° C) is used, but it may occur even in an ink having a viscosity of 1 to several cp (25 ° C).

The reason why 1- (2,3-dihydroxypropyl) -benzotriazole is effective in suppressing the wear of the ball seat is presumed as follows. That is, 1-
Since (2,3-dihydroxypropyl) -benzotriazole has a large chelating power for metals such as nickel silver and stainless steel used for ballpoint pen tips, 1- (2,3-dihydroxy) is present on the metal surface of the ball seat. It forms a chelate of a derivative of propyl) -benzotriazole. As a result of the chelate acting as a cushion between the ball and the ball receiving seat, the abrasion resistance between the ball and the ball receiving seat is reduced, and the wear of the ball receiving seat is reduced.

For Example 2 and Comparative Example 2, the ball sinking was measured from the difference between the ball protrusion length before writing and the ball protrusion length after 500 m continuous writing. The ball protrusion length was measured with a tool microscope by measuring the length from the fore edge of the ballpoint pen tip to the tip of the ball.
