摘要：
Disazo compounds in which two monoazo dyestuff molecules of the general formula
IN WHICH D represents the residue of heterocyclic diazo component, A represents an arylene residue and R'' and R'''' each represents an alkyl residue, are linked together via their coupling components through a bifunctional bridging group Z which has no dyestuff characteristics and which contains at least one quaternated nitrogen atom. The compounds are used for dyeing synthetic fibers such as polyvinyl chloride and demonstrate good light and washing fastness.
