摘要：
The process for the continuous dyeing of synthetic fiber materials in which the fiber materials are impregnated with a dyeing liquor comprising an organic solvent and an anthraquinone dyestuff of formula
IN WHICH B and B'' independently of one another represent a C1C9- alkyl, cycloalkyl or aralkyl radical, Ha1 and Ha1'' denote a halogen atom, each of m and n is a number from 0-3, with the proviso that the sum of m+n is at least 1, and each of p and q is a number from 0-2; and the dyed materials are subsequently subjected to a heat treatment. The dyeings obtained are distinguished by high dyestuff yield, very good buildup and excellent fastness properties, especially very good fastness to thermofixing, washing, rubbing and light.
