Hair dye agent comprising aminopyrimidine derivatives

Agents for coloring and/or matting keratinic fibers, in particular human hair, include in a cosmetic carrier at least one specific substituted 1,4-diaminoanthraquinone derivative of formula (I), wherein the residues (R2, R4) mutually independently denote a grouping of formula (II). The cosmetic method of using these agents can be for producing intense blue shades and for matting keratin fibers. 

Means for dyeing and/or matting keratinic fibres containing novel 1,4 diaminoanthraquinone dyes

An agent for oxidative coloring of keratin-containing fibers, in particular human hair, includes as oxidation dye precursor of the developer type at least one compound of formula (I). 

Oxidation dye precursors

The present specification provides for an agent for coloring keratinic fibers. The agent includes, a cosmetic carrier, a compound of formula (I), R1 and R2 independently of one another denote hydrogen, a C-Calkyl group, a C-Calkenyl group, a hydroxyl group, a halogen, a C-Calkoxy group, an amino group, a nitro group, an acetyl amino group, or a sulfonamide group; or when in ortho-position to one another, form a 5- or 6-membered, saturated or unsaturated ring, which optionally include further heteroatoms.
