摘要:
A novel chromogenic substrate to peroxidase enzymes is provided which is comprised of a mixture of a colorless mixture of two compounds, such as, 3-methyl-2-benzothiazolinone hydrazone and 2-hydroxy-2,4,6-cycloheptatrienone, which undergo an oxidative coupling in the presence of peroxidase and hydrogen peroxide forming a purple indamine dye. Under certain circumstances the dye will precipitate out from the buffered solution and thus provide a permanent record of the determination. The mixture is also stable and unaffected by oxygen of the air or by hydrogen peroxide.
摘要:
A dye composition for keratinous fibers comprising a specific type of trifluoromethylated aniline derivative, as a developer, and a coupling substance is disclosed. The composition provides high degree of saturation and vividness of colors as well as good fastness. Dyeing with the use of the dye composition ensures a variety of developer-coupling agent combinations, which can provide a wide variety of colors with a high degree of color saturation and vividness. The color produced possesses excellent light resistance, washing resistance, and wear resistance.
