Sulfoalkyl aminophenyl disazo dyes
Abstract
Abstract Compounds useful as light fast yellow, orange and red dyes for natural and synthetic polyamide fibers and for secondary cellulose acetate fibers, have the structure: ##SPC1## Wherein R 1 is alkyl, benzyl, cyclohexyl, --C--CH 2 CH 2 OH, ##EQU1## ##EQU2## --CH 2 CH 2 CN, --CH 2 CH 2 --O--COCH 3 , or ##EQU3## R 2 is --H, -alkyl, halogen, --O-- alkyl or --NH--COR 4 ; R 4 , as used in R 2 , R 3 , R 5 and R 6 , represents -alkyl, -tolyl, -phenyl or -halophenyl; and B 1 is a benzene ring or a benzene ring substituted with substituents which may be selected from nitro, halogen, cyano, alkyl, alkoxy, trifluoromethyl, alkylsulfonyl, acetyl, carboxamido, sulfonamido, N-alkyl-sulfonamido, N,N-dialkylsulfonamido, N-alkylcarboxamido and carboxyl groups; B 2 is a 1,4-naphthylene or a 1,4-phenylene group of the structure: ##SPC2## Wherein R 5 is --H, alkyl, -alkoxy, or --NHCOR 4 ; R 6 represents --H, alkyl, alkoxy, --NHCOR 4 , --NH--SO 2 --R 4 or halogen; and M is --H, --Na, --K, --Li or --NH 4 .
