Dressler and coworkers dyed polypropylene yellow by treating polypropylene containing nickel with 2,5-bis(o-hydroxyphenyl)thiazolo[5,4-d]thiazole. The yellow color resulted from the formation of a nickel/2,5-bis(o-hydroxyphenyl)thiazolo[5,4-d]thiazole coordination compound (see Dressler, H. et al. U.S. Pat. No. 3,326,627).
