| abstract |
The present invention is excellent in so-called cap-off performance (dry-up resistance) due to blurring due to drying of a pen tip and inability to write, and also occurs under a high humidity condition due to a local decrease in ink viscosity due to moisture absorption in a pen tip portion. Provided is an aqueous ink composition for a writing instrument that does not cause dripping or ink dropping. A water-based ink composition for a writing implement comprising at least water, a colorant, a water-soluble organic solvent, and a sugar mixture containing at least 40% by weight of saccharides having 10 or more saccharides.
