N-Aminoalkylenesulfonamido substituted monoazo colorants
First Claim
1. A mixture consisting essentially of a monoazo compound which is substituted with an average of x (N-substituted sulfonamido) groups per molecule wherein said monoazo compound is of the formula ##STR25## in which x represents a number from 1 to 4,R represents hydrogen or the moiety ##STR26## in which R4 is hydrogen, C1 to C3 alkoxy or C1 to C3 alkyl,R1 represents a moiety selected from the group consisting ofalkylene-NH-alkylene-NH2,alkylene-N-(C1 to C4 alkyl)2, ##STR27## in which alkylene represents --CH2 CH2 -- and --CH2 CH2 CH2 --,R3 represents hydrogen, C1 to C3 alkyl or C1 to C3 alkoxy;
- orthe acid-addition salt forms of said mixtures of monoazo compounds.
