Abstract

Fiber-reactive dyestuffs, processes for their preparation and their use Dyestuffs of the formula (1) are described ##STR1## The dyestuffs have fiber-reactive properties and dye materials containing hydroxy groups and/or containing carboxamide groups, in particular fiber materials, such as, for example, cellulose fibers, wool and synthetic polyamide fibers, in deep, fast shades by the methods known for this process.
