Dyes from 2-amino-5-nitrothiazole, such as (48) e.g. 53USP2659719), have high extinction coefficients and are reddish-blues to blues depending upon the substitution pattern in the coupler, a subject which has recently received attention (e.g. 79MI11202). 

The uptake of anionic dyes from acidified solutions by polyamides has traditionally been treated as Langmuir sorption on sites usually identified with the terminal amino-groups of the polymer75,76). It was also early realized that additional sorption can occur at sufficiently low pH, known as overdyeing 75,76). 

Co111 exhibits a greater tendency to form complexes with nitrogen-donor ligands than with oxygen-donor ligands. Thus the azo dye from diazotized 2-amino-1 -hydroxybenzene-5-sulfonamide and acetonylbenzthiazole affords the 1 2 cobalt...
