Abstract: Leather is simultaneously dyed and finished using a coloured polymer in which the dye is bound to the polymer by a covalent bond. The polymer may be obtained by copolymerizing a dye bearing at least one polymerizable olefinically unsaturated group with one or more polymerizable monomers (many listed) or the polymer may be one on to which a copolymerizable dye has been grafted or the polymer may be attached to the dye by way of reactive groups both on the polymer and the dye. The polymers may be in solution or dispersion, preferably aqueous dispersion. The coloured polymers may contain reactive groups, e.g. by using N-methylolacryl- or methacrylamide as a comonomer, through which cross-linking may be effected. The coloured polymers may be applied by brushing, dipping or spraying or in a drum. The so-treated leather may afterwards be glazed or plated. Examples are given. Specifications 877,402, 914,282, 946,472, 964,757 and 965,627 are referred to.

Abstract: Azo dyes of the formula in which R and R in each case denote optionally substituted C1-C10-alkyl or optionally substituted C3-C4-alkenyl or R additionally denotes hydrogen, R denotes hydrogen or C1-C6-alkyl, R and R in each case denote hydrogen, C1-C6-alkyl, halogen, C1-C6-alkoxy, amino or C1-C4-mono- or dialkylamino and D denotes a radical from the thiophene, thiazole, isothiazole, benzothiophene, thienothiophene or thienothiazole series and their use for dyeing or printing textile fibres or fabrics or for thermal transfer.

Abstract: Metal-coated melamine-formaldehyde resin fibres in which the coating is obtained by first reducing a water-soluble metal salt using a more electronegative metal or metal salt, or first reducing a water-soluble metal salt using a hydride compound and then applying the desired metal to the fibre by reduction of one of its water-soluble salts with a reducing agent in the presence of a complexing agent.

Abstract: Process for the preparation of I acid urea of the formula in which 7-amino-4-hydroxynaphthalene-2-sulphonic acid (I acid) is subjected to partial reaction with urea in an inert solvent at a temperature from 100 to 140 DEG C and a pressure from atmospheric pressure to 10 bar, unreacted I acid is precipitated in an acidic medium and removed, and, if appropriate, I acid urea is separated from the resulting neutralised solution by adding salt.
