PURPOSE:To provide a high-quality color image having outstanding properties such as water-proofing, light fastness, resistance against ozone, clarity and mutual color scheming by ensuring that yellow ink is based on a chemical compound as shown by a specific formula as a dye, and magenta ink contains a specific pigment and cyan ink contains a specific dye. CONSTITUTION:At least, ink colors such as yellow, magenta and cyan are donated to a recording medium material to form a color image. The yellow ink contains at least, one of chemical compounds as a dye which are shown by formula I (A is the binding of formulae I and II; X1, X2 are -SO3M, -COOM or a phenyl group and a naphtyl group which can be substituted with hydroxyl; R is a methyl group, n is 0 r 1, M is an alkali metal). In addition, the magenta ink contains at least, one pigment selected from C. I. Pigment-Red5, etc., and cyan ink contains at least, one dye selected from among C. I. reactive blue 14, etc. |
