ABSTRACT:

The invention concerns a composition for the dyeing of human hair on aqueous basis, which comprises at least one direct-acting hair dyestuff. Such hair dyeing compositions have been known for some time.
They usually comprise several anionic or cationic direst-acting dyestuffs and, in difference to the permanent hair dyeing compositions on the basis of oxidation dyestuff precursor products, they require no prior development with oxidation agents.
These direct-acting compositions are either applied together with surface-active substances as so-called tinting shampoos, or they are applied onto the hair as lotions, emulsions or thickened lotions, i.e. gels.
With regard to their color stability and especially intensity as well as evenness of the coloration and color gloss, these direct-acting hair dyeing compositions can still be improved.
The invention therefore starts from the task of creating a hair dyeing composition on the basis of direct-acting dyestuffs, which can be applied onto the hair as a lotion, emulsion, solution, gel, suspension or, also, with the addition of propellants, as aerosol preparation, and which shows excellent coloration properties, providing stable colorations over an extended period of time.
This problem is solved by adding to such a composition at least one direct-acting dyestuff on the basis of a compound of formula (1)
wherein R
1
is a halogen atom; R
2
and R
4
are an optionally OH— or NH
2
-substituted C
1
-C
4
-alkyl group or phenyl group and R
3
stands for H
1
or an optionally OH— or NH
2
-substituted C
1
-C
4
-alkyl group or phenyl group.
Preferred compounds are those of the formulas (2) and (3)
The preparation of these compounds is known per se and is carried out by transfer of the respectively substituted acetamides or acetanilides with the respectively substituted haloaminobenzoles.
The colors thus obtained are mainly in the range of intensive yellow and gold but can be varied by the addition of further dyestuff shades.
The proportion of direct-acting dyestuffs in the compositions according to the invention is variable and ranges between about 0.001% to about 5%, preferably 0.01% to 2.5%, in particular 0.1% to 1% by weight, calculated to the total composition.
As stated above, in addition to the compounds of formula (1), it is possible to incorporate further direct-acting hair dyestuffs to modify the shades.
Preferred are the so-called “Arianor” dyestuffs; see K. Schrader, “Grundlagen und Rezepturen der Kosmetika”, 2nd Ed., (1989), p. 811.
Especially suited basic (cationic) dyestuffs are.

as well as the dyestuffs known from EP 0681 464 B1.
It is, of course, also possible to use the respective direct-acting plant dyestuffs or also anionic (acidic), direct-acting hair dyestuffs.
These are customarily also used in an amount of about 0.005% to about 5%, preferably about 0.05% to about 2.5%, in particular about 0.1% to about 1% by weight, calculated to the total composition, which is present as solution, dispersion, emulsion, gel or aerosol preparation for direct application.
