Abstract

1301747 Metal complex disazo dyestuffs FARBWERKE HOECHST AG 2 Feb 1970 [1 Fob 1969] 4861/70 Heading C4P The invention comprises copper, cobalt, or chromium complex disazo dyestuffs which in the metal free form and in the form of the free acid have the general formula wherein R and R<SP>1</SP> each represent an alkyl or cycloalkyl group, or together with the nitrogen atom form a heterocyclic ring; m and n each equal 0, 1 or 2, the sum of m and n being either 1 or 2; and the benzene nuclei A and A<SP>1</SP> may carry, further substituents. The dyes may be prepared by coupling a copper, cobalt or chromium complex of a monoazo dye of formula with a diazo compound of an amine of formula Alternatively, disazo dyes containing a sulphatoethyl sulphone, chloroethylsulphone or vinyl sulphone group in the rings A and A<SP>1</SP> may be reacted with an amine of formula The dyes give greenish blue shades on cellulose and nitrogen-containing fibres. Reference has been directed by the Comptroller to Specification 898,094.
