    摘要： A black recording having high solubility, being stable even after being stored for long, and capable of forming a printed image with a high optical density and excellent water and light resistances. The recording fluid contains a trisazo compound of general formula (1): wherein D is an 8-hydroxy-1-naphtyl group substituted with one or two sulfo groups; A is a 1,4-phenylene group or 1,4-naphtylene group which may be substituted with amino, hydroxy, alkyl, alkoxy, acylamino or ureido; and B is a phenyl group which may be substituted with hydroxy, amino or sulfo, or a salt thereof and is used for the recording.

    摘要： Problems The present invention provides an ink composition which, when applied as an ink-jet recording solution to plain paper and processed glossy paper, assumes vivid yellow color and gives printed material excellent in light fastness, gas fastness and moisture fastness. Means for Solving the Problems Ink-jet printing with an ink-jet ink composition containing a disazo compound represented by the following formula (1) can give a vivid yellow-colored product excellent in light fastness, gas fastness and moisture fastness (in the formula (1), X represents specific diamine residue; and Y1 and Y2 each represent an alkylamino group substituted with a sulfonic acid group and/or a carboxyl group, a phenoxy group substituted with a sulfonic acid group and/or a carboxyl group and an anilino group substituted with a sulfonic acid group and/or a carboxyl group).
