Abstract
An ink composition contains colored cellulose fibers and a dispersion medium containing water and a water-soluble organic solvent in a weight percentage of 1% to 95%. The ink composition contains colored cellulose fibers acting as the color material capable of being easily trapped in the meshes of the printing medium, that is, the color material having a small diffusion coefficient into the printing medium, and has a wettability as high as a contact angle of 90 degrees or less on the printing medium. Thus, the bleeding and strike-through of the ink composition can be prevented when the printing medium is printed.
