    摘要: Extremely bright, tinctorially strong disperse dyes derived from diaminomaleonitrile and selected aromatic and heterocyclic aldehydes, and their preparation, useful for dyeing and printing polyester and polyester-cotton blend fibers in yellow to blue shades of generally good fastness properties, which dyes are of the general formulaAr.sub.1 -CH=N-C(CN)=C(CN)-N=CH-Ar.sub.2wherein Ar.sub.1 and Ar.sub.2 are aromatic or aromatic-like groups, for example, phenyl or pyridyl.
