Patent number: 6514328Abstract: A marking ink composition contains a dye, a pigment, a dispersion medium X in which the dye is practically soluble, and a dispersion medium Y in which the dye is practically insoluble, the dispersion media X and Y being mutually immiscible. A display medium includes a marking ink composition, and two plates for holding the marking ink composition therebetween, at least one of the plates having a transparent portion. A method for printing an image on an image receiving material includes the steps of depositing the above-mentioned marking ink composition on the image receiving material, and removing the dispersion medium X and the dispersion medium Y from the image receiving material. There is also described an image printed on an image receiving material by the above-mentioned printing method.Type: GrantFiled: February 4, 2000Date of Patent: February 4, 2003Assignee: Ricoh Company, Ltd.Inventors: Ikuo Katoh, Hitoshi Kondoh, Kunio Hayakawa, Mitsunobu Morita, Kyohji Tsutsui, Takashi Okada
