摘要

Use of at least one catiu00c8nico azo compound, composition for dyeing, the dyeing process of the fiber queratinicas device, multiple compartments or staining kit and cationico azo compound.This application concerns the use for colouring fibres queratu00ednicas, in particular human queratu00ednicas fibres such as the hair, cationic azo compounds with julolidina units for direct dyes.The present application is also a dyeing composition for the dyeing of fibres queratu00ednicas, in particular of the fibres such as the hair, human queratu00ednicas that consists of a means of tincture appropriate at least one direct azo dye with julolidina cationic units.The present application is also a process of dyeing of fibres queratu00ednicas, in particular of queratu00ednicas fibres such as the hair, using the composition according to the present invention dye. This application is also certain azo compounds catiu00f5nicos particu Households with julolidina unit.
