摘要： An aqueous ballpoint ink composition which comprises titanium oxide as white pigment, a viscosity modifier and flaky resin particles. This composition permits color matching with colorants (such as pigments) and exhibits a viscosity of 100 to 20,000 cP at 20 DEG C. The flaky resin particles have a mean particle diameter of 0.05 to 10 mu m and the content thereof is 1 to 35 wt.% based on the whole ink composition. The content of titanium oxide is 5 to 50 wt.% based on the whole ink composition. Further, polysaccharides are used as the viscosity modifier and the content thereof is 0.1 to 2 wt.% based thereon.

摘要： The present invention provides an aqueous ink composition for ball-point pens comprising a titanium oxide as a white pigment, a viscosity modifier and flat-shaped resin particles. The color of the aqueous ink composition can be adjusted by coloring agents (such as a pigment). The viscosity of the aqueous ink composition is 100 cps to 20,000 cps at 20 °C. The average particle diameter of said flat-shaped resin particles is 0.05 µm to 10 µm and the content thereof is 1 % by weight to 35 % by weight with respect to the total amount of the aqueous ink composition. The content of the titanium oxide is 5 % by weight to 55 % by weight with respect to the total amount of the aqueous ink composition. As a viscosity modifier, a polysaccharide is used and the content thereof is 0.1 % by weight to 2 % by weight with respect to the total amount of the aqueous ink composition.
