Title dyes composition useful for dyeing the cellulose fibers comprise the compound (I), (II) and (III) or their metal salts. In formulas, R1-2 is H, alkyl or alkoxy; X is -CH2CH2OSO3H or -CH=CH2. Thus, 1-Aminobenzene-4,.BETA.-sulfate ethylsulfone 11.47wt. parts is dispersed in water and diazotized with addition of hydrochloric acid(35%) 4.03wt. parts and sodium nitrite 9.44wt. parts. The obtained diazo compound is mixed with compound(I) which is obtained by coupling reaction of 1-amino-8-naphthol-3,6-disulfonic acid and diazo compound prepared from 1-aminobenzene-4, .BETA.-sulfate ethylsulfone and 2-aminoacet-8-naphthol-6-sulfonic acid. The mixed solution is spray-dried to give title dyes.
