Abstract
A liquid ink composition for an impact printer, comprising a dye and an oily substance as an essential component, the dye being insoluble in the oily substance and dispersed in the oily substance. An ink ribbon for an impact printer using the liquid ink composition is also disclosed. The use of the liquid ink composition reduces wear and corrosion of the printing wires used in a wire dot printer and gives print images with no blurring.
