DYE COMPOSITION OF ACIDIC PH COMPRISING 2,3-DIAMINO-6,7-DIHYDRO-1 H,5H-PYRAZOLO[1,2-A]PYRAZOL-1-ONE, A PARA-PHENYLENEDIAMINE, A META-AMINOPHENOL AND AN OXIDIZING AGENT, AND PROCESSES FOR DYEING KERATIN FIBERS USING THE COMPOSITION . |
摘要 |
The present disclosure relates to a composition for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising at least one first oxidation base chosen from 2,3-diamino-6,7-dihydro-1H,5H-pyrazolo[1,2-a]pyrazol-1-one and the addition salts thereof, at least one second oxidation base chosen from para-phenylenediamines, at least one coupler chosen from meta-aminophenols and at least one oxidizing agent, the pH of the composition ranging from 5.5 to 7.5. The present disclosure makes it possible to obtain a coloration on keratin fibers with tints in red, coppery or mahogany tones that are sufficiently visible on natural or dyed hair and uniform from the roots to the ends.
