Dye composition containing a cationic direct dye and a pyrazolo¬1,5-a| pyrimidine as oxidation base, and dyeing processes

摘要

Composition (I) for oxidation dyeing of keratinic fibers comprises at least one pyrazolo(1,5-a)pyrimidine developer (II) and at least one cationic direct dye (III) and contains no enzyme system capable of causing oxidation of (II). Independent claims are also included for the following: (1) a method for dyeing keratinic fibers, comprising applying at least one composition (I) to the fibers and developing the color with a non enzymatic oxidizing agent, which is added to (I) just before use or is present in an oxidizing composition applied simultaneously or sequentially; (2) a kit comprising a compartment containing (I) and a compartment containing an oxidizing composition containing a non enzymatic oxidizing agent.
