Abstract: Fiber-reactive 1:2-chromium complex compounds containing one atom of metal linked in complex union with a monoazo dyestuff molecule and with a disazo dyestuff molecule containing the grouping

IN WHICH N 1 OR 2, AND WHICH FURTHER CONTAIN ONE OR SEVERAL FIBER-REACTIVE GROUPINGS ARE SUITABLE FOR DYEING OR PRINTING WOOL, SILK, SUPERPOLYAMIDE FIBERS, AND POLYHYDROXYLATED FIBROUS STRUCTURES SUCH AS REGENERATED CELLULOSE AND VISCOSE FIBERS, LINEN AND COTTON. The resulting dyeings are even and have good fastness to light, washing, fulling, decatizing, carbonizing and abrasion. The new dyes are valuable to obtain neutral grey and black tints.
