  • Publication number: 20080295259
    Abstract: Provided are a method of stabilizing a leuco dye storable as a liquid for a long time, a method of reducing nonspecific color development thereof at a time of a color development reaction, and a stable liquid reagent composition using the methods. The inventors of the present invention found that coexistence of the leuco dye with a specific reducing agent resulted in suppression of self color development and its remarkably improved stability in a solution, and that when a color development reaction of the leuco dye with hydrogen peroxide was performed, coexistence of the leuco dye, in a reaction solution, with another dye which had an absorption spectrum not influencing a measurement wavelength of the leuco dye and did not react with hydrogen peroxide suppressed nonspecific color development and lowered a reagent blank value, which was applied to an analytical reagent.

  • Patent number: 7399319
    Abstract: Disclosed herein is a method for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising applying to the keratin fibers a dye composition comprising at least one compound chosen from styryl and imine compounds comprising a heterocycle that can undergo opening and/or dyes corresponding to these compounds whose heterocycles are open. The compositions and methods of the present disclosure may produce a coloration of keratin fibers that is chromatic and fast with respect to external factors such as shampooing, does not stain, and/or allows simultaneous dyeing and bleaching of keratin fibers.
