Abstract
Abstract An image recording ink composition for use in a printer for recording letters and images with a liquid ink is disclosed, comprising water and a coloring material and containing at least one water-insoluble component. The ink composition is excellent in rapid drying properties, fixing properties, freedom from obstruction in a printing machine, and preservability, and provides an image excellent in terms of blurring, density, gloss, water resistance, and light resistance.
