  • Publication number: 20090049621
    Abstract: The present invention relates to the use, for the dyeing with lightening effect of human keratin substances, and in particular of human keratin fibres such as the hair, of a composition comprising at least one fluorescent cyanine dye. The present invention allows human keratin substances to be both dyed and at the same time lightened without detriment to said substances. The fluorescent dyes employed in the context of the invention also have high tinctorial affinity for keratin substances and good properties of resistance towards external agents, and especially towards shampoos.

  • Publication number: 20090031506
    Abstract: Novel energy transfer dyes which can be used with shorter wavelength light sources are provided. These dyes include a donor dye with an absorption maxima at a wavelength between about 250 to 450 nm and an acceptor dye which is capable of absorbing energy emitted from the donor dye. One of the energy transfer dyes has a donor dye which is a member of a class of dyes having a coumarin or pyrene ring structure and an acceptor dye which is capable of absorbing energy emitted from the donor dye, wherein the donor dye has an absorption maxima between about 250 and 450 nm and the acceptor dye has an emission maxima at a wavelength greater than about 500 nm.
