Abstract: The novel basic azo dyes free from sulphonic acid gps. are of formula (I): D(+)-N=N-A-NR-CH2-C(Z)=CH2 X(-) (I) (where D(+) is the radical of an aromatic or heterocyclic diazotisation component contg. a quaternary N atom. A is an aromatic radical or with -NR- forms a heterocyclic radical, R is H opt. substd. lower alkyl, or aralkyl or cycloalkyl, X(-) is an anion, Z is H, halogen, or lower alkyl). Used for dyeing/printing of natural or synthetic fibre textiles. (I) may be in powder or liq. form.

Abstract: Title cpds are of formula (I) (where A is a single bond, an opt. branched alkylene gp. with at least 2C atmos opt interrupted by hetero-atoms a divalent gp or an isocyclic or heterocyclic ring, cycloalkylene- or dicycloalkylene-alkane gp; one X is COOH and the other is H or COOH, the benzene ring a may carry other substits. Dyes colours in yellow-orange shades.
