2-nitro-4-benzenesulfonamido chlorobenzenes

(57) Abstract

A keratin fiber dye composition which comprises a solvent and a dyeing amount of a dye compound having the formula: in which n is a whole number between 2 and 6 inclusive, and R2 and R3, which may be identical or different, are selected from the group consisting of hydrogen, lower alkyl, lower hydroxyalkyl, and with the nitrogen atom adjacent R2 and R3 may form morpholino and piperidino, each R1, R2, R3 having 1-6 carbon atoms on their alkyl portion, AND THE PROCESS OF DYEING KERATIN FIBERS. IN WHICH R'' is selected from the group consisting of methyl and NO2, and R'''' is selected from the group consisting of hydrogen and lower alkyl, having 1-6 carbon atoms, AND R1 is selected from the group consisting of lower alkyl, lower hydroxyalkyl, lower alkoxyalkyl, and D R A W I N G IN WHICH R is selected from the group consisting of lower alkyl, hydroxy alkyl, carboxyalkyl, carbethoxyalkyl, carbamylalkyl, haloalkyl, aminoalkyl, aminodialkyl, alkylaminodialkyl, alkyl morpholino, alkyl piperidino, having 1-6 carbon atoms on each mentioned alkyl portion, Z is selected from the group consisting of
