Abstract: Dyestuff mixtures comprising at least one azo dyestuff whose diazo component is 2-amino-3,5-dicyano-4-methylthiophene and whose coupling component originates from the 2-amino-4-thienylthiazole series, and at least one azo dyestuff whose diazo component is 2-amino-3,5-dicyano-4-methylthiophene, 2-amino-3-alkoxycarbonyl-5-cyano-4-methylthiophene or 2-amino-5-alkoxycarbonyl-3-cyano-4-methylthiophene and whose coupling component originates from the 3-cyano-4-methyl-2,6-diaminopyridine series, and/or at least one azo dyestuff whose diazo component is a 2,6-dicyano-4-alkylaniline and whose coupling component originates from the m-phenylenediamine series, and the use of the novel dyestuff mixtures for the dyeing or printing of synthetic fabrics.

Abstract: Stabilised aqueous C14- to C22-alkyldiketene emulsions containing, as essential components, (a) 10 to 60 % by weight of at least one C14- to C22-alkyldiketene, (b) 1 to 10 % by weight of at least one protective colloid and (c) 0.1 to 20 % by weight of at least one ester of the formula in which R , R are C14- to C22-alkyl, in which case R and R must differ in the alkyl group by at least 4 C atoms, and/or denote identical or different C14- to C22-alkenyl groups, an ester of the formula R -O-CO-O-R (II), in which R and R are alkyl or alkenyl radicals having 2 to 22 C atoms or a urethane of the formula in which R , R and R are identical or different alkyl or alkenyl radicals having 2 to 22 C atoms, and the use of the compounds of the formula I to III as stabiliser for the preparation of alkyldiketene emulsions containing at least 10, preferably 16 to 40 % by weight of alkyldiketene in emulsified form.
