| titleOfInvention | Sulfo group-free disazo and polyazo compounds containing at least two basic or cationic group and which are in metal-free or 2:1 metal complex form |
| abstract | Disazo and polyazo compounds of the formula ##STR1## wherein each A is independently ##STR2## and n each R 1 and the ##STR3## radical to which it is attached, taken together, independently, are ##STR4## wherein ring B may be substituted by one substituent selected from halogen, C 1-4 alkyl and C 1-4 alkoxy, and each R 3 is independently C 1-4 alkyl, or n wherein the ** denotes the carbon atom attached to X, or each A, R 3 and the ##STR5## radical to which they are attached, taken together, independently, are each R 1 and the ##STR6## radical to which it is attached, taken together, independently, are the radical of an aromatic carbocyclic or heterocyclic coupling component, ##STR7## wherein each R 21 is independently halo, C 1-4 alkyl or C 1-4 alkoxy, n p is 0, 1 or 2, n the * denotes the carbon atom attached to the --N═N-- radical, and n the ** denotes the carbon atom attached to X, n each n A 1 and A 2 taken together are --O--Me--O--, wherein Me is copper, cobalt, iron, nickel, manganese or zinc, or n each n A 1 is hydroxy, and n each n A 2 is independently hydrogen, hydroxy or C 1-4 alkoxy, n X is a direct bond or a bridging radical, n each n Y is independently a direct bond, C 1-4 alkylene, --CO--NH--(CH 2 ) m -***, --NH--CO--(CH 2 ) m *** or --SO 2 --NR 4 --(CH 2 ) m -***, wherein R 4 is hydrogen or C 1-4 alkyl, n m is 1, 2, 3 or 4, and the *** denotes the carbon atom attached to the Z group, each Z is independently ##STR8## wherein A.sup.⊖ is a non-chromophoric anion, n m is 1, 2, 3 or 4, and n p is 0, 1 or 2, and n n is at least 2, n with the provisos that (i) the compound is free of sulfo groups, and (ii) when the compound is in metal-free form, each A, R 3 and the ##STR9## radical to which they are attached form a group of formula (b) and each R 1 and the ##STR10## radical to which it is attached together form a 1-phenylpyrazole group the phenyl ring of which is substituted by one --Y--Z group, which compounds are useful for dyeing and printing paper, leather, textile materials comprising natural or regenerated cellulose (for example, cotton, mercerized cotton, alkali treated cotton, hemp, sisal, jute and flax) and fibers, yarns and textile materials comprising polyamide or polyester modified to contain acid groups. |
