Abstract

Procedure to prepare disazoic water soluble dyes that, in the form of the free acid, have the general formula: **(See formula)** wherein ring B can be optionally substituted by sulfonic acid and/or hydroxyl groups and E represents a residue of formula: **(See formula)** wherein R1 represents hydrogen, optionally substituted alkyl or optionally substituted aryl, R2 represents hydrogen or optionally substituted alkyl and R3 and R4 independently represent hydrogen, lower alkyl, lower alkoxy, halogen or acylamino; or **(See formula)** wherein R5 represents hydrogen, alkyl, acyl or aryl optionally substituted by alkyl, alkoxy, halogen, hydroxy or acylamino, p has a value of 0, 1 or 2, provided that the total number of sulfonic acid groups in the dye do not exceed 3, and m has a value of 0 or 1; characterized in that it comprises diazotizing a primary amine of the formula: **(See formula)** copulate with an aminonaphthalene of formula: **(See formula)** wherein ring B can optionally be substituted by sulfonic acid and/or hydroxyl groups and then diazotize the aminomonoazoic compound and couple with an amino group-containing coupling component of the formula: **(See formula)** where R1, R2, R3 and R4 are defined as above, or (ii) **(See formula)** where R5, m and p are defined as above.
