Prepared similar to Congo Red paper, the dye thiazole yellow (Clayton Yellow) being employed. 

Chlorophenine, chloramine yellow, diamine fast yellow B, F F, and C, Clayton -yellow, thiazol yellow, thioflavine S, etc. Primuline developed with hypochlorite. 

Blends between thiazole yellow and the polythiophene 534 have been reported (07MI275). The polythiophene showed an absorption band at 520 nm. Electrical and photovoltaic properties have been studied. 

Chloramine Yellow FF (Naphthamine Yellow NN) and Thiazole Yellow... 

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-... 

Various types of dyes are prepared from dehydrothiotoluidine. The free base or its sulfonic acid is diazotized and coupled with various naph-tholsulfonic acids such as, for example, e acid (l-naphthol-3,8-disul-fonic acid). The resulting dye is characterized by its high purity of color and can be discharged to a pure white. Such red direct dyes are sold under various names, and are usually referred to as dyes of the erika red type. (Erika Z is the combination from dehydxothioxylidine and e acid. l-Naphthol-3,6-disulfonic acid gives a very similar dye.) In addition to the true azo dyes from dehydrothiotoluidine, two other products are made which are important yellow dyes. One of these dyes is the naphthamine yellow NN (also called chloramine yellow) (Kalle), formed from dehydrothiotoluidinesulfonic acid by oxidation with sodium hypochlorite. The other is thiazole yellow or Clayton yellow, which is made by combining the diazo compound of dehydrothiotoluidinesulfonic acid with a second molecule of the same compound to form a diazoamino compound. 

Thiazole yellow is changed by sodium hydroxide from a pure yellow to a bright red, and it can be used, therefore, as a reagent to test for alkali (thiazole paper). 

Products analogous to chloramine yellow and thiazole yellow can be prepared from primuline, but these dyes give much muddier colors and are redder and weaker so they have found little favor.
