Dyeing Performance of Dyes Derived from 2-Amino Heterocycles on Leather

Iyun O.R.A.*, Bello K.A., Putshaka J D, Tanko S F, Abdullahi S.

The dyeing properties of dyes synthesized from 2-amino-4-phenylthiazole (Dye 1) and 2-amino-4-methyl-5- carbathoxythiazole (Dye 2) on leather were studied. The effects of pH, temperature, dye concentration, dyeing time as well as rubbing and light fastness properties of the dyes were evaluated. Results obtained indicate that the dyes used were abso...
