Azoic Dye

Name:
Azoic Dye
Detailed information:
There is no fundamental chromophoric difference between azo and azoic dyes. The differentiation is made to characterize a group of azo pigments which are precipitated within the cellulosic fiber by carrying out the dye coupling on the fiber. With the advent of the equally brilliant but more easily applied fiber-reactive dyes, the azoics have lost some of their importance.
