ボールペン用インキに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water-based ink composition for ballpoint pens. In detail, it reduces wear on the ball and socket, maintains smooth ink flow, extends the effective writing distance, and also prevents line skipping during high-speed writing (smooth rotation of the ball). The present invention relates to an ink for a water-based ballpoint pen that eliminates the phenomenon in which the writing line is partially interrupted due to the lack of water, resulting in discontinuous markings.

とは困難であった。また、後者では。Various proposals have been disclosed in an attempt to overcome these drawbacks. For example, in Japanese Patent Application Laid-Open No. 52-81380, water-soluble silicone resin, Japanese Patent Publication No. 57-87184
The publication describes an example in which each unsaturated fatty acid is blended. However, while the former provides sufficient lubricity, the surface tension is significantly reduced, resulting in bleeding phenomena on the paper surface, ink scattering due to drops, or ink ink when left upright (leaving the writing section facing upward). It was difficult to put it into practical use because it caused problems such as an inability to write due to dropback. Also, in the latter.

させるものである。Unsaturated fatty acids themselves have extremely low solubility in water, leading to defects such as phase separation within the ink storage body, dark and light writing lines, and sticky handwriting due to the slow drying properties of unsaturated fatty acids. 0 The present invention is characterized in that an oligomer of N-vinyl-2-pyridone is blended, thereby significantly improving the various performances described at the beginning without causing the defects described above.

これを持続させる適度の粘性を付与する。The oligomer used in the present invention is represented by the general formula %, and is disclosed in West German Patent No. 1040081.
Synthesized with reference to the above publication. The oligomer has an affinity for the ball and socket members (metal, plastic), and provides appropriate wettability effective for ball rotation within an appropriate range and appropriate viscosity to maintain this wettability.

If the amount added is less than 0.5% by weight, the lubricating effect is poor, and if it is in excess of 50% by weight. This significantly increases the viscosity of the ink, impairs the flow of the ink in the ink guiding section, and impedes ink followability.

It is also possible to further improve writing performance.

The sample ballpoint pen was used to write with a rotating optical writing tester adjusted to a writing load of 100g and a writing angle of 70°, and the ink consumption was calculated from the constant value of the weight of the ballpoint pen at 2 times per 100m.
The effective writing distance was defined as the end point at which the value became 70 N9/ ] 00 m or less. Further, the ink consumption rate is expressed by the following formula.
