Abstract
Process for the preparation of cationic dyes of starting materials and by-products, which are in pure form both in the technical aspect and in the dyeing and corresponding to the formula i ** (see formula) ** In which R1 denotes a methyl, ethyl or propyl group; R2 is a hydrogen atom or has one of the meanings of the symbol r1, And corresponds to one of the formulas ** (see formula) ** Where B means a hydrogen atom or a low molecular weight alkyl, cyclohexyl, phenyl or benzyl radical, which may be substituted with low molecular weight cyano, nitro, carbamoyl, hydroxyl, amino or alkoxy groups or with chlorine or hydrogen atoms. Bromine; D denotes a phenyl ring or a pentagonal or hexagonal heterocyclic ring to which another benzene ring may be juxtacondensed, which may be substituted with chlorine or bromine atoms or with low molecular weight alkyl or alkoxy or phenoxy groups, nitro or acetyl, or else which forms, with the radical b and the nitrogen atom, a pentagonal or hexagonal ring; Q denotes a bridge member which in addition to carbon may also contain heteroatoms and which completes z by forming a pentagonal or hexagonal ring; Z carries the same substituents as d and may contain one or two juxtacondensed benzene rings; R3 means a methyl, ethyl, propyl or benzyl radical; Each of the subscripts M and n is 1 or 2; y A ⊖ denotes an anion, Characterized by continuously quaternizing a dye of the formula ii ** (see formula) ** In which And, q, z, n and r2 have the same meaning as in formula (I), In aqueous medium, preferably alkaline, and at temperatures of 5 to 75º c, with dimethyl sulfate, diethyl sulfate or dipropyl sulfate or with methyl or ethyl ester of p-toluenesulfonic acid and a total amount of 4 moles of dialkyl sulfoester added, at the most, per mole of dye.
