    摘要: Valuable dyestuff formulations for dyeing polyester fibres are obtained without expensive finishing techniques by simple mixing of emulsifiers with dyestuffs of the formula ##STR1## wherein A=alkylene,B and D=a direct bond or a bridge member,V and Q=hydrogen, alkyl, alkenyl, cycloalkyl, aralkyl, aryl or acyl,X and Y=a non-ionic substituent,m and n=0 to 3 andp and r=0 to 10, with the proviso that p represents 3-10 if r=0 or 1 and D=a direct bond.The dyeing formulations are present in the liquid or dissolved form under the dyeing conditions. The use of dispersing agents, protective colloids, levelling agents and carriers is thus superfluous.
