| 摘要 |
This invention relates to colorants comprising organic chromophores, in particular reactive dyes, which comprise electrophilic reactive groups, and which are also covalently bonded to fatty amine moieties through amino linking groups. Such colorants provide excellent colorability and long-term stability, both within (or on) colored substrates and upon long-term storage. Such colorants exhibit particularly good coloring and stability within hydrocarbon compositions, such as fuels, mineral oil, and the like, and wax compositions, including candles, crayons, and the like. Methods of making such colorants as well as methods of coloring hydrocarbon and wax compositions are also contemplated within this invention.
