Orange dye mixtures of fiber-reactive azo dyes and use thereof for dyeing material containing hydroxy groups-and / or carboxamido.

摘要

The present invention dye mixtures refers orange reactive with suitable fibers for dyeing materials containing hydroxyl and / or carboxamido, such as cellulose fibers, type of cotton or wool and nylon, comprising one or more dyes of monoazo corresponding to the general formula (1) and one or more dyes of monoazo corresponding to the formula (2) (formula) wherein each of D {sub, 1} and D {sub, 2}, independently, is a radical of a benzene nucleus or naphthalene, each of R {sub, 1}, R {sub, 2}, R {sub, 3} and R {sub, 4} is, independently, hydrogen, methyl, ethyl methoxy, ethoxy, sulfo or carboxy, M is hydrogen or an alkali metal and each of the groups Y {sub, 1} -SO {sub, 2} - and Y {sub, 2} -SO {sub, 2} - is a reactive fiber groups vinylsulfone series.
