    Abstract: The invention comprises water-soluble azo dyestuffs having at least one heterocyclic radical which contains at least one group as part of the heterocyclic ring, attached by way of an amino group and also having at least one hydroxyl group esterified with sulphuric acid or with an aryl carboxylic acid containing at least one sulphonic acid group in the aryl radical, but no sulphonic acid groups linked in any other way. The dyestuffs are made by (a) esterifying an azo dyestuff containing at least once the heterocyclic radical and at least one free hydroxyl group with sulphuric acid or an appropriate aryl carboxylic acid, or (b) reacting an azo dyestuff containing at least once the esterified hydroxyl group and at least one primary or secondary amino group with a heterocyclic compound containing as part of the heterocyclic ring at least two groups, or (c) coupling a diazo component containing at least once the heterocyclic radical with a coupling component containing at least once the esterified hydroxy group, or (d) coupling or diazo component containing at least once the esterified hydroxyl group with a coupling component containing at least once the heterocyclic radical, or (e) coupling a diazo component containing at least once the heterocyclic radical and at least once the esterified hydroxyl group with a coupling component free from sulphonic acid groups. Heterocyclic compounds containing at least two groups are cyanuric chloride and phenyl dichlortriazine. The esterified hydroxy group may be attached to alkyl or aryl radicals. The dyes colour fibres of wool, silk, polyamides, leather and paper.

    Abstract: Tetrazaporphin dyes containing sulphonic acid N-(primary amino alkyl)-amide groups are made by (a) reacting a tetrazaporphin sulphonic acid -1:2- alkylenimide or a tetrazaporphin sulphonamide which contains on the amido nitrogen a hydroxyalkyl radical esterified with a hydrogen halide or a strong oxygen-containing acid of sulphur or phosphorus, with ammonia or a reagent which yields ammonia, such as ammonium carbonate or bicarbonate or urea, or (b) reacting a tetrazaporphin sulphonamide having two hydrogen atoms on the amido nitrogen with a 1:2-alkylenimine or a primary halogenoalkylamine. The reactions may be conducted in aqueous or organic media and examples are given. The dyes dye or print leather, paper and textile materials of native and/or regenerated cellulose particularly in the presence of acid-reacting reagents or alkaline-reacting reagents. The tetrazaporphin alkylenimide and sulphonamide starting materials are made by reacting tetrazaporphin sulphonyl halides with alkylenimines, with haloalkylamines, with hydroxyalkylamines esterified with strong oxygen-containing acids of sulphur or phosphorus or with hydroxyalkylamines and then esterifying the product, for example, with thionyl chloride or bromide, sulphuric or chlorsulphonic acid, alkyl- or aryl-sulphonic acid halides or phosphoric or polyphosphoric acid.

    Abstract: The invention comprises a process and compositions for dyeing, printing and/or fluorescent brightening of textile materials using a dye or fluorescent brightening agent containing at least one reactive hydrogen atom, or a group which is capable of forming one or more such atoms during the process preferably attached by a nitrogen, sulphur or oxygen atom, and a heterocyclic compound substituted by at least three epoxy groups or by two epoxy groups and at least one CH2 = CH-CO- group or a group convertible into such a group during the process, and optionally an alkaline reacting agent, a dispersing agent and/or a protective colloid, and/or one or more dyeing and/or printing auxiliaries. The reactive hydrogen atoms are found in the following groups which characterize the dyes employed, primary or secondary amino groups, -NH- groups in heterocyclic combination, sulphonamide groups, sulphonic alkylamide groups, sulphonic arylamide groups, carboxylic amide groups, carboxylic alkylamide groups, hydroxyl and/or sulphhydryl groups. Water soluble or insoluble dyes may be used including substantive and reactive dyes. The heterocyclic compounds used are those preferably having the formula:- in which X is an organic radical containing an epoxy group or is convertible into an epoxy group, and Y is X-O-CH2-CH2- or is CH2=CH- or a radical convertible into one of these radicals. A group capable of being converted to an epoxy group is the halohydrin group and groups capable of conversion to CH2=CH-CO- include b -chloropropionyl groups and quaternary groups of type Conventional dyeing processes are used but preferably the material is treated with dye liquors or printing pastes containing the alkaline reacting agent, the dye and the heterocyclic compound as above. Materials processed are made from natural and regenerated cellulose, polyvinyl alcohol cellulose esters, polyacrylonitrile and its copolymers, linear polyesters, wool, natural silk and linear polyamides. Specifications 628,821, 768,470, 869,549 and 900,372 are referred to.
