The compounds of the formula (1) are suitable for dyeing carboxamido- and/or hydroxy-containing materials, in particular fiber materials, such as wool, synthetic polyamide, in particular cellulose fibers. If applied to the materials using in particular the application and fixing methods customary for fiber-reactive dyes they produce strong fast dyeings in predominantly orange to red shades.
