Cationic 1,2,3-thiadiazole-azo-aniline or tetrahydroquinoline compounds

Abstract

Abstract The invention relates to novel 1,2,3-thiadiazole-axo compounds of formula ##STR1## wherein R is unsubstituted or substituted alkyl or alkenyl, R 1 is hydrogen or unsubstituted or substituted alkyl or alkenyl, R 2 is hydrogen or unsubstituted or substituted alkyl, alkenyl, cycloalkyl or phenyl, or R 1 and R 2 , together with the nitrogen atom to which they are attached, are a 5- or 6-membered heterocyclic ring which may contain one or two additional hetero atoms as ring members and/or may be substituted, or R 1 together with R 3 ortho to the amino group form a partially hydrogenated, unsubstituted or substituted 5-or 6-membered heterocyclic ring which may contain an additional N or O atom as ring member, R 3 and R 4 are each independently of the other hydrogen, alkyl, alkoxy, alkanoylamino or halogen, R 5 is hydrogen or together with R 4 in ortho-position forms the member which completes a fused benzene ring, R 7 is hydrogen, optionally substituted phenyl or alkyl, and X⊖ is an anion. These compounds are suitable for dyeing or printing acrylic, acid-modified polyamide and acid-modified polyester fibres in blue shades.
