A process for manufacturing a dispersion dye involves (a) reacting an organic solvent (IV) with a compd. (V) in the presence of an alcohol of R3OH and alkali metal hydroxide to obtain a compd.(VIII), (b) coupling the product (VIII) with diazonium salt of formula(III): where R1=H, C1, methoxy, ethoxy, or phenoxy, R2=methy1, eyhy1, or pheny1, R3=methy1, ethy1, propy1, i-propy1, n-buty1, i-buty1, t-buty1, pheny1, cyclohexy1, benzy1, R4=H, methy1, ethy1, propy1, i-propy1, n-buty1, t-buty1, -C2H4OH, R5=hydroxy or acetoxy, X=H, C1, Br, methy1, ethy1, methoxy, ethoxy, cyano, Y=H, methy1, ethy1, propy1, i-propy1, n-buty1, i-buty1, t-buty1, Z=C1, Br, I.
