Abstract

The present invention provides an aqueous pigment ink for ball-point pen which can inhibit surface tension from extremely deteriorating to protect written letters from blur and which is excellent in non-drying properties and which has lubricating properties enough to smoothly rotate a ball and to decrease friction of a ball seat, whereby a writing performance can be remarkably improved and a comfortable writing performance can be given.
The aqueous pigment ink composition for ball-point pens of the present invention is characterized by comprising a pigment, a dispersant, water and an adduct of at least one polyhydric alcohol with an alkylene oxide, the polyhydric alcohol being selected from the group consisting of polyglycerin, glycerin, trimethylolpropane and a mixture thereof.
