摘要：
A water base ink composition which comprises water as a solvent, a carboxyl group containing styrenic resin having an average molecular weight of 1500-30000 and an acid value of 150-300, in an amount of 2-20% by weight, a basic dye in an amount of 0.1-80 parts by weight in relation to 100 parts by weight of the styrenic resin, and an alkali which is volatile at normal temperatures in such an amount as adjusts the ink composition at a pH in the range of 6 to 8.5.
