    摘要: Disazo compounds of the formula

    IN WHICH R1 and R6 each represents a hydrogen or a halogen atom or a nitro, alkyl or alkoxy group, R2, R3, R4 and R5 each represents a hydrogen atom or an alkyl or alkoxy group, X represents an amino group bound to the -SO2 bridge by way of its nitrogen atom and Y represents an alkyl group or a group of the formula B-SO2-, in which B represents a low-molecular alkyl group or a benzene residue and in which the benzene ring A can be fused to another benzene ring and the Y-O group is in ortho- or paraposition to the azo bridge, are valuable dyestuffs suitable for the spin-coloration of cellulose esters.
