Abstract
A process for the preparation of azo dyes, which correspond to the general formula ** (Formula) ** where A represents the remainder of a hydroxylated and/or aminated monopulant or a bi-copulant AH2, optionally substituted with one or two methyl groups or one sulphonic acid group, or of the hydroxylated and/or aminated naphthalene series, optionally substituted with one sulphonic acid group; B represents the remainder of a diazotable primary BNH2 benzene amine; n is O or 1; R represents a methyl or carboxylic acid group; R1 and R2 represent a hydrogen or chlorine atom; R3 is a hydroxy group or a hydrogen atom and R4 is a sulfonic acid group or a hydrogen atom, which consists in subjecting the bis-diazoic derivative of a mole of 3,4'' - diamino benzenesulfanilide with a mole of an N-sulfophenyl-5-pyrazolone substituted in position 3 with a methyl or carboxylic acid group; then subjecting the thus obtained monoazodiazoic compound to the coupling reaction in a basic medium with one mole of a monosulfonated monoaminonaphthalene coupler, optionally substituted with a hydroxy and/or sulfonic acid group, in this order of coupling which is preferred or in reverse order; the monoaminated bisazoic derivative obtained is then subjected to a diazotizing reaction and coupling with one mole of a monocoupler or a bicopulant AH2 and the dye obtained can optionally be coupled with a mole of a diazo derivative of a benzene amine BNH2.
