  • Publication number: 20030005854
    Abstract: In a ball pen which is formed to have an ink-consumption value per unit area of 0.64 to 1.6 mg/cm2, the water content is adjusted in the range from 30.0 to 80.0 wt %, the content of a volatilization-inhibiting substance in the range from 0.1 to 10.0 wt % and the content of a hardly-volatile water-soluble liquid medium in the range from 1.0 to 40.0 wt % in the ink for a ball pen in order to achieve both the quick-drying property of the ink transferred onto the paper surface and the non-drying property of the point of the pen-tip and further a good writing feeling.

  • Patent number: 6451099
    Abstract: Provided is a water based ink composition for a ball point pen comprising at least one selected from the group consisting of an alkylene oxide adduct of polyglycerin, an alkylene oxide adduct of glycerin and an alkylene oxide adduct of trimethylolpropane and further comprising a colorant, a white plastic pigment, a viscosity-controlling agent and water. The ink composition is excellent in a writing property as well as a coloring property of the drawn lines regardless of the kind of writing paper and is stable with the passage of time. In addition thereto, it provides the drawn lines with a color having the same color tone as that of the visual color when it is charged into an ink reservoir.

  • Patent number: 6379441
    Abstract: Disclosed are a cyan ink containing a copper phthalocyanine dye which can realize images much less susceptible to deterioration upon exposure to visible light, a yellow or magenta ink, to be used with a cyan ink containing a copper phthalocyanine dye, capable of realizing color images much less susceptible to deterioration upon exposure to visible light, and an ink set comprising at least a cyan ink, a yellow ink, and a magenta ink and capable of realizing color images much less susceptible to deterioration upon exposure to visible light. The copper phthalocyanine dye undergoes color change and fading upon exposure to visible light. This is considered attributable to deterioration and decomposition of the dye by photo-oxidation or photo-reduction.
