Disazo compounds containing a cyanoamidotriazinyl radical as a bridging member (middle component) and fiber-reactive groups of the vinylsulfone series, suitable as dyestuffs

摘要

Disazo compounds which possess fiber-reactive groups and have useful dye properties and are capable of dyeing hydroxyl- and/or carboxamido- containing materials, in particular fiber materials, such as cellulose fibers and natural and synthetic polyamide, such as wool, in strong, fast shades. They conform to the formula ##STR1## wherein the substituents are as defined in the specification.
