Some relatively simple pyridines have been used as hair dyes. Thus (100) is fast-yellow on white hair (79JAP7923631) and (101) fast-red when used in conjunction with hydrogen peroxide (79JAP7928330). More typical azo derivatives, for example (102) and (103), have... 

Picric acid is a strong acid, very toxic, soluble in hot water, alcohol, ether, benzene and acetone, and is a fast yellow dye for silk and wool. It attacks common metals, except for aluminium and tin, and produces salts which are very explosive. The explosive power of picric acid is somewhat superior to that of TNT, both with regard to the strength and...

Metal complexes of tetradentate azomethines, e.g. (199), are reported136 to have very high light-fastness but to be tinctorially weak and dull in hue. Despite this they are of technical interest as very fast yellow to brown pigments. They find no application as dyestuffs, however, because of these deficiencies for example, the chromium complex of (200) gives dull, tinctorially weak dyeings on wool possessing poor wet-fastness properties.

Anthrimide Carbazoles. Fast vat dyes are produced by carbazole ring closure from a,a-dianthraquinonylamines (anthrimides). The shade is determined by the number and position of the carbazole systems and by additional substituents, especially acylamino or alkoxyl groups. Anthraquinone carbazoles make it possible to dye cellulose fibers in level, very fast yellow, orange, brown, gray, and olive shades. However, this series lacks dyes with bright shades. 

Exhaustively alkylated 4-aminodiphenylamine is also suitable as a coupling component. Dyes such as 6 [41025-69-8], obtained by reaction with diazotized nitroanilines, confer fast yellow, orange, and red shades to polyacrylonitrile [27],... 

By coupling of diazotized 3-aminopyridine to 2-naphthol, followed by quater-nization, dyes (e.g., 46 [41313-61-5]) are obtained that color polyacrylonitrile in fast yellow shades and exhibit excellent leveling characteristics [134],... 

A series of dyestuffs have been reported which contain the pyrido[2,3-p]-l,2,4-triazine and pyrido[4,3-e]-1,2,4-triazine nuclei. These compounds have been used to dye a number of fibres fluorescent yellow shades <74GEP(0)2417916>. Another series of polyheterocyclic dyestuffs which contain a pyridotriazine moiety have been patented as fast yellow dyes especially for synthetic fibres <75GEP(0)2355967>. Amongst a number of the compounds prepared as dyestuffs were several 1H-pyrido-l,3,4-thiadiazines. The compounds were used to dye polyester fibres fast shades of yellow <77USP4025510>. 

Azo yellow is acid fast and can be used satisfactorily for dyeing tin phosphate weighted silks. It is indispensible for producing water fast yellow and brown tints. 

Naphthamine yellow NN is the most light-fast yellow for cotton and is completely stable to chlorine. Because of these properties, it is widely used, especially in the United States where laundry is always treated with bleaching agents. Naphthamine yellow NN is not as pure a color as chrysophenine and is inferior also with respect to color strength. 

Thiazole yellow (Clayton yellow, mimosa, etc.) is, in contrast to chloramine yellow, the least fast yellow of the entire dye industry and it is really astonishing that such an inferior dye is used at all. It has, how-...
