Abstract

Il presente trovato concerne un procedimento per la colorazione di materiali, in particolare di pelli e simili, già colorati.In particolare è utilizzabile per la colorazione, con colori più chiari, di pelli e simili già precedentemente colorate con colori più scuri.Secondo il trovato la singola zona da colorare viene prima trattata con un ossidante, in grado di attaccare chimicamente il colorante preesistente, e successivamente trattata con un miscuglio formato dal colorante col quale si vuole dare il nuovo colore e da un riducente in grado di neutralizzare i composti derivati dalla precedente ossidazione.The present invention relates to a process for coloring materials, in particular of hides and the like, already colored. In particular, it can be used for coloring, with lighter colors, of hides and the like already previously colored with darker colors. the single area to be colored is first treated with an oxidant, capable of chemically attacking the existing dye, and subsequently treated with a mixture formed by the dye with which you want to give the new color and by a reducing agent capable of neutralizing the compounds derived from the previous oxidation.
