REACTIVE DYES BASED ON COPPER FORMAZANE
The invention relates to novel copper-formazan reactive dyes which contain one or two chromophore radicals derived from a copper-formazan of the formula in which R denotes hydrogen, hydroxysulphonyl, C1- to C4-alkoxy or chlorine, R denotes hydrogen or hydroxysulphonyl, and one of the two radicals R...

Summary: | The invention relates to novel copper-formazan reactive dyes which contain one or two chromophore radicals derived from a copper-formazan of the formula
in which R denotes hydrogen, hydroxysulphonyl, C1- to C4-alkoxy or chlorine, R denotes hydrogen or hydroxysulphonyl, and one of the two radicals R and R denotes hydrogen and the other denotes hydroxysulphonyl, or, if at least one of the two radicals R and R is hydroxysulphonyl, R and R may alternatively simultaneously be hydrogen, and, as reactive anchors, two or three halotriazine radicals, to the salts thereof, and to the use of the novel dyes for dyeing or printing organic substrates containing hydroxyl groups or nitrogen. |
