Abstract:
Disclosed are compounds of formula (1) or formula (2). The compounds are useful for the dyeing of organic materials, such as keratin fibers, wool, leather, silk, cellulose or polyamides, especially keratin- containing fibers, cotton or nylon, and preferably hair, more preferably human hair. (1) (2).
Abstract:
Chemically reactive dyes that are intramolecularly crosslinked with a water-soluble bridge, their bioconjugates and their uses are described. Reactive fluorescent dyes that have a water-soluble bridge are superior to those of conjugates of spectrally non-crosslinked dyes or the dyes that are crosslinked with a hydrophobic bridge. The invention includes reactive fluorescent dyes, their biological conjugates and uses.
Abstract:
