| titleOfInvention | Naphtholsulphonic acid compounds, their preparation and use as coupling components |
| abstract | Compounds which contain ammonium groups and sulphonic acid groups and which, in the betaine form, correspond to the formula ##STR1## wherein X denotes --CO-- or --SO 2 --, n R 1 denotes hydrogen or alkyl, n R 2 , R 3 and R 4 , independently of one another denote alkyl, alkenyl or aralkyl, or n R 4 denotes ##STR2## Y denotes alkylene or xylylene, m denotes 1 or 2, n n denotes 0 or 1, and n R 5 and R 6 , independently of one another, denote hydrogen, alkyl, alkoxy or halogen, n and in addition, if n=1, n R 2 or R 4 denotes amino, alkylamino, dialkylamino, aryl or cycloalkyl, n R 2 and R 3 , together with the nitrogen atom which is bonded to them, denote a 5-membered or 6-membered ring, n R 2 , R 3 and R 4 , together with the nitrogen atom which is bonded to them, denote a pyridinium ring, a group of the formula ##STR3## or hydrogen, Y denotes arylene, benzylene or a radical of the formula ##STR4## Z denotes a direct bond, --(CH 2 ) p --, --O--, --O--(CH 2 ) p --O--, --SO 2 --, --NHCO--, --NHCONH--, --NHCO--(CH 2 ) p --CONH-- or --CONH--(CH 2 ) p --NHCO--, n p denotes 1, 2 or 3, and n R 7 denotes hydrogen, alkyl, alkoxy or halogen, n and wherein the cyclic and acyclic radicals can contain non-ionic substituents, their preparation and their use as coupling components in the preparation of azo dyestuffs. |
