Abstract

Procedure for the preparation of water soluble disazo dyes of the formula (1) **(See formula)** or complex disazo dyes with copper, cobalt or chromium, which in metal-free form would correspond to formula (2) **(See formula)** where A means the radical of a diazo component of the benzene or naphthalene series, T means a hydrogen atom or a low molecular weight hydroxyl, carboxyl or alkoxy group, X means a hydroxyl or carboxyl group, B means the radical of a coupling component of the benzene, naphthalene or pyrazolone series, D means a divalent bridge member or Y means a group of the formula (3) -SO2-CH = CH2 (3) or a group of the formula (4) -SO2-CH2-CH2-Z (4) -Z here means a hydroxyl group or an organic or inorganic radical capable of being separated in alkaline medium, m means a number from 1 to 6, n means the number 0 or 1 and p means a number from 1 to 3, and in which the Nucleus C or C'may also contain other substituents, characterized in that 1 mol of an aminoazo dye of formula (5) is diazotized. **(See formula)** in which A, C, C', T and X have the aforementioned meanings, and is coupled with a coupling component of the formula (7) **(See formula)** in which B has the aforementioned meanings, the components being chosen in such a way that the resulting disazo dye, apart from 1 to 6 sulfonic acid groups, contains 1 to 3 substituents of the formulas (3) or (4), and The disazo dyes thus obtained are optionally reacted with an agent that yields copper, cobalt or chromium, and the hydroxyl group of the group -SO2-CH2-CH2-OH is optionally esterified with sulfuric acid or with a compound that yields sulfur trioxide.
