    Abstract: The invention comprises monoazo dyes, free from SO3H groups, of the formula wherein R is an aliphatic or cycloaliphatic residue which may be substituted and A is an indole or hydroxyquinoline residue alkylated in 1-position and free from sulphonic acid groups. They may be obtained by diazotizing and coupling the corresponding 3- or 4-aminophthalimides with appropriate indoles or hydroxyquinolines alkylated in 1-position. Specified R radicals are methyl, ethyl, propyl-(1), propyl-(2), n-butyl-(1), n-butyl-(2), isobutyl, tertiary-butyl, 2-ethylhexyl or cyclohexyl which may be substituted by hydroxy, alkoxy or substituted or unsubstituted amino groups. Examples are given for the production of the dyestuffs. They may be used in finely divided form for dyeing and printing various forms of textile materials derived from cellulose esters or ethers, or synthetic fibre-forming materials, such as polyacrylonitrile and copolymers of acrylonitrile; and linear polyamides, polyurethanes or polyesters greenish yellow or reddish yellow shades.

    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.
