Abstract: Process for the preparation of styryl dyestuffs of the formula (I) in which R1 and R2 denote hydrogen, alkyl, alkoxy or halogen and X denotes an alkylene radical, characterized in that compounds of the formula (II) in which X, R1 and R2 have the meaning given for formula (I) and R denotes alkyl or aryl, are hydrolyzed by means of mineral acid to give compounds of the formula (I) and the latter are isolated.

Abstract: Polyester fibres are dyed in yellow and orange-red color shades with good fastness to light and wet processing when dyestuffs of the formula wherein K denotes the radical of a 5-amino-pyrazole coupling component which couples in the 4-position, R denotes an optionally substituted alkyl, cycloalkyl, aralkyl or aryl radical and the ring A can contain further non-ionic substitutents customary in dyestuff chemistry, are used.

Abstract: Polyurethane plastics are dyed with dyestuffs of the formula wherein R1 denotes hydrogen, halogen, optionally substituted C1-C4-alkyl, optionally substituted C1-C4-alkoxy and optionally substituted C1-C4-alkylcarbonylamino and R2 denotes hydrogen, optinally substituted C1-C4-alkyl and optionally substituted C1-C4-alkoxy, while A and B denote optionally branched alkylene chains which can be identical or different and preferably have 2 to 6 carbon atoms, with formation of covalent bonds, in that the dyestuffs are added before or during the polyaddition reaction to the reacton mixture of polyol and polyisocyanate or to one of the components.
