ABSTRACT:
A disazo dye composition comprising at least a disazo dye represented by the formula (I) and a disazo dye represented by the formula (II): ##STR1## (wherein X and Y indicate an alkoxy group having 1 to 4 carbon atoms, and M indicates hydrogen or a cation selected from the group consisting of, alkaline metal, NH.sub.4, alkyl-substituted ammonium, alkanolammonium, morpholinium and piperidinium), wherein, when the disazo dye composition is analyzed by liquid chromatography, the area ratio of the peak area (Sp) of the disazo dye represented by the formula (I) to the peak area (Sc) of the disazo dye represented by the formula (II), that is Sp:Sc is from 1:0.4 to 1:2.4. This disazo dye composition provides a high quality image, rapid ink fixing and the like even on the plain paper.
