摘要

b fluorescent dye, composition for dyeing, dyeing process of raw multicompartimento queratinicas, device and use of fluorescent dyes d the present invention refers to the colour of materials queratu00ednicos using the fluorescent dyes of thiol / disulfide. I understand a group ortho piridu00ednio and a chain alkylene interrupted.And a dyeing process, which has a whitening effect nosmateriais queratinicos, in particular, the queratu00ednicas fibres, in particular human queratu00ednicas fibres such as the hair, using this composition. It refers in a manner similar to fluorescent dyes of thiol and if The US uses in the bleaching of raw queratu00ednicas.This composition makes it possible to obtain a whitening effect visible and particularly strong in the fibers queratu00ednicas dark
