Name:
Azine Dye
Detailed information:
A class of dyes derived from phenazine. (C₆H₄)N₂(C₆H₄) (tricyclic). The chromophore group may be ═C═N—, but the color is more probably due to the characteristic unsaturation of the benzene rings. The members of the group are quite varied in application. The nigrosines (CI 50415–50440) and safranines (CI 50200–50375) are examples of this group.See Dye, Synthetic.
