Anthraquinone dyes of the formula ##STR1## where R is C.sub.1 -C.sub.10 -alkyl, C.sub.5 -C.sub.8 -cycloalkyl, alkoxyalkyl of a total of 3 to 11 carbon atoms, phenoxyalkyl, where alkyl is of 2 to 4 carbon atoms, or phenyl-C.sub.1 -C.sub.4 -alkyl. On synthetic fibers and blends thereof with cellulosic fibers, the dyes give brilliant clear blues. The dyes are particularly suitable for transfer printing onto synthetic fibers and give high color yields. The transfer prints obtained have excellent fastness characteristics.
蒽醌染料的化学式为##STR1##其中R为C.sub.1 -C.sub.10 -烷基,C.sub.5 -C.sub.8 -环烷基,总碳原子数为3到11的烷氧基烷基,苯氧基烷基,其中烷基为2到4个碳原子,或苯基-C.sub.1 -C.sub.4 -烷基。在合成纤维和混纺纤维上,这些染料呈现出明亮清晰的蓝色。这些染料特别适用于在合成纤维上进行转移印花,并且具有高色彩产量。所得的转印品具有优异的色牢度特性。
