    摘要: A recording medium containing a substantially colorless compound in which at least 10 atoms having conjugate π electrons are present on a per-molecule basis, wherein it is especially preferable that the compound has at least two aromatic ring groups and/or shows no fluorescence. An ink composition used for printing in image form on media, with the composition containing a dye and controlling a hue change caused in the printed images over a period of one hour immediately after the printing to 5 or below in color-difference terms. And a method of recording images on media by printing an ink composition in image form, wherein the ink composition contains a dye and a hue change caused in the printed images over a period of one hour immediately after the printing is controlled to 5 or below in color-difference terms.
