Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
Fibre-reactive disazo dyestuffs of the formula ##STR13## wherein R 1 to R 4 independently of one another denote hydrogen, a low-molecular alkyl group or a low-molecular alkoxy group, R 5 denotes hydrogen or a low-molecular alkyl group n is 1, 2 or 3 and R 7 denotes hydrogen, low-molecular alkyl, aryl, aralkyl, or cycloalkyl, and the benzene or naphthalene ring A in addition to the sulfonic acid groups, can be substituted by C 1 -C 4 -alkyl, C 1 -C 4 alkoxy, carboxyl, halogen, C 1 -C 4 -alkylcarbonylamino or benzoyl amino; the naphthalene ring B in addition to the sulfonic acid group can be C 1 -C 4 -alkoxy substituted and the benzene radical D in addition to the sulfonic acid group in 2-position can be substituted by one sulfo or carboxyl group, by C 1 -C 4 alkyl, C 1 -C 4 alkoxy, halogen, C 1 -C 4 -alkylcarbonylamino or benzoylamino groups.

Claim 4
Dependent Claim
35 words
Fibre-reactive disazo dyestuffs of the formula ##STR15## wherein R 1 to R 5 have the meaning given in claim 1 and R 8 and R 9 together form a 5-membered or 6-membered ring containing oxygen.
