PURPOSE: The titled ink providing a ball-point pen having smooth ink release, not causing paper sliding phenomena, exhibiting improved decalcomania properties, obtained by adding 2,4,7,9-tetramethyl-5-decyne-4,7-diol, etc. as one component to a blended composition.
CONSTITUTION: A water-soluble dye, antiseptic, etc. are added to an aqueous solvent obtained by adding 5W20wt% water-soluble polyfunctional alcohol, e.g., ethylene glycol, etc. to water as a main component, to give an aqueous ink composition. This composition is blended with one or more of 2,4,7,9-tetramethyl-5- decyne-4,7-diol shown by the formula I, an adduct shown by the formula II (m and n are integer) of 2,4,7,9-tetramethyl-5-decyne-4,7-diol with ethylene oxide, and 3,6-dimethyl-4-octyne-3,6-diol shown by the formula III in an amount to give preferably 0.05W0.3wt% based on composition calculated as total amount, to give the desired ink.
