Disperse Dyes: Dyeing Properties and Fastness of Azo Dyes

Textile Research Journal, 1977
The dyeing properties and fastness of several disperse azo dyes, prepared from the o- and m-substituted p-nitroani-lines as diazo components and N-ethyl-N-cyanocthylanilinc and - o-anisidine as coupling components, have been studied in order to get an idea of the substitutional effect on dyeing properties.
