| titleOfInvention | Ink composition for ballpoint pen and ballpoint pen |
| abstract | The ink composition is an ink composition containing at least a colorant and a liquid medium, provided with at least one receiving plate in the recess of the pot, and a rotatable ball at the tip while contacting the receiving plate. Using a measuring machine equipped with a fixed rotor, installed in an ink composition bath containing 1 cm 3 of the ink composition in the recess of the pot, inclined 45 degrees with respect to the rotation axis of the rotor The load in the normal direction of the bearing plate is pressed against the bearing plate with a force of 2.12 N while rotating the ball, and the circumference of the ball at the contact point of the ball and the bearing plate by the rotation of the rotor When the circumferential velocity is increased from 0.00001 m / sec to 1.40 m / sec under the condition that the circumferential velocity is increased 10 times at intervals of 67 seconds, the above-mentioned bearing plate and the ball Friction between In the measurement to obtain the coefficient, the material of the seat plate and the ball is SUS 316, and the coefficient of friction is measured at a temperature of 25 ° C. and the peripheral velocity in the range of 0.05 m / sec to 1.0 m / sec. Is a value less than the friction coefficient .mu..beta. When the circumferential speed is 0.001 m / sec, and 0.4 m / sec is added to the peripheral speed V.alpha. From the circumferential speed V.alpha. M / sec showing the friction coefficient .mu. An ink composition for a ballpoint pen characterized by having a coefficient of friction μγ at a peripheral speed and a value of μγ-μα of 0.3 or less. |
