Abstract:
WATER INSOLUBLE AZO DYESTUFFS FREE FROM SULPHONIC ACID AND CARBOXYLIC ACID GROUPS OF THE FORMULA
1-(R-N=N-),2-X,4-(R1-N(-R2)-),5-Y-BENZENE
IN WHICH R IS A RADICAL OF THE BENZENE OR HETEROCYCLIC SERIES; X IS ACYLAMINO; Y IS HYDROGEN, HALOGEN, ALKYL OR ALKOXY; R1 IS
R3-O-CH(-R7)-CH(-R6)-O-CH(-R5)-CH(-R4)-
R4, R5, R6 AND R7 ARE HYDROGENS OR LOWER ALKYL RADICALS WITH 1 TO 2 CARBONS; R3 IS HYDROGEN OR -COR8; R8 IS AN OPTIONALLY SUBSTITUTED LOWER ALKYL RADICAL; R2 IS CNH2N+1; AND N IS AN INTEGER FROM 1 TO 4. THE DYESTUFF ARE USEFUL FOR DYEING HYDROPHOBIC FIBERS, E.G. AROMATIC POLYESTERS.
