ABSTRACT:
The present invention is an aqueous ink composition for ball-point pen comprising an aqueous ink mixture containing at least a pigment or colored polymer emulsion, a dispersant, a water-soluble organic solvent and water, and a compound of the general formula (1). Examples of such ink compositions include a sodium salt of polyoxyethylene alkyl ether phosphate monoester a sodium salt of polyoxyethylene alkyl ether phosphate diester, a triethanolamine salt of polyoxyethylene alkylphenyl ether phosphate monoester, triethanolamine salt of polyoxyethylene alkylphenyl ether phosphate diester. The aqueous ink composition provides a lubricity effect of rotating a ball smoothly when it is used for a ball-point pen. Therefore, the aqueous ink compositions are superior in lubricity and hence are free of clogging at the tip of ball-point pen even after prolonged use: ##STR1## wherein R 1- is -OX or R 2 -O-(CH 2 CH 2 O)n-; R 2 is C 8 to C 18 which is alkyl group, alkenyl group, or alkylphenyl group;
