Printing ink composition

摘要

A printing ink composition is provided comprising water, a coloring agent and at least two types of polyoxyalkylene glycol alkylethers each having at least one oxyalkylene in its polyoxyalkylene group, wherein at least one of the polyoxyalkylene glycol alkylethers is polypropylene glycol-n-butyl ether having three or more oxypropylenes in its molecule. This printing ink composition can inhibit color bleeding not only on a printing medium specifically designed for ink-jet printing but also on plain paper.
