Description

Comprise at least a painted lightening composition with the direct dye of positive ion that mixes chromophore

The present invention relates to comprise the dye composite of the direct dye of positive ion that contains different chromophores, in particular for the painted compositions of keratin fiber blast (lightening).The invention still further relates to the colouring method that uses said composition, and relate to the purposes that said composition is used for the keratin fiber blast.

With the especially human hair of the dye composite dyeing keratin fibres that contains oxidation dye precursors, be known practice, described oxidation dye precursors is commonly referred to oxidation base, for example neighbour or p-phenylenediamine (PPD), neighbour or para-aminophenol and heterocyclic compound.These oxidation bases are colourless or the chemical compound of light colour, when combining with oxygenated products, can produce colored compound by the oxidative condensation process.

It is also known to these oxidation bases are combined with colour coupler or dyeing regulator, the tone that is obtained by these oxidation bases may change, and colour coupler or dyeing regulator particularly are selected from for example benzazolyl compounds of two amines between aromatic series, m-aminophenyl phenols, a diphenols and some heterocyclic compound.

Can obtain shades of colour as the various molecules of oxidation base and colour coupler are feasible.

This oxidation dyeing method is to apply to keratin fiber the mixture of developing alkali or developing alkali and colour coupler, and uses aqueous hydrogen peroxide solution as oxidant, makes the mixture rinsing fiber then of having an effect on fiber.The dyeing that is obtained by said method is permanent, dense and anti-external factor, particularly fast light, vile weather, washing, sweat and friction.Usually this method of carrying out at alkaline pH makes dyeing and blast fiber to carry out simultaneously, and this is come out by the final staining reaction that can obtain than primitive color brighter (lighter) in practice.In addition, the fiber blast has in the higher advantageous effects of probability that produces the advantageous effects of consistent color under the situation of gray hair and Show Color just makes Show Color under the situation of natural colour hair.

Coming dyeing keratin fibres by direct staining also is known practice.The method that is generally used for direct staining is to apply direct dyes to keratin fiber, and described direct dyes is the colored dyeing molecule that fiber is had affinity, makes the described dyestuff rinsing fiber then of having an effect on fiber.

For example using, direct dyes or azo, xanthene, acridine, azine or the triarylmethane class dyestuff of nitrobenzene, anthraquinone dye, nitropyridine class are known practices.

These direct dyess can be made up of one or more chromophores, and these chromophores can be identical or different.The dyestuff of being made up of several chromophores for example is described among document FR1540423, EP1133975, EP1133976, US5708151 and the WO 02/078596.

The dyeing of using direct dyes to obtain is temporary transient or semipermanent dyeing, because direct dyes is attached to interactional essence on the keratin fiber and direct dyes from fiber surface and/or fibre core desorbing, be the reason of direct staining power difference and fastness to washing and color fastness to perspiration difference.

Some direct dyes can be combined with oxidant, thereby can realize the blast of fiber painted the time.For example, patent application EP 810851 has described the dye composite that contains direct dyes, and described direct dyes contains the quaternized nitrogen-atoms of at least one azo or azomethine type, and described dye composite can mix with oxidising composition immediately at alkaline pH.

But the gained color is not always satisfactory aspect the fastness of color.They disappear under the effect of shampoo, may be seen indistinctly on the keratin fiber of blast.In addition, when dye composite comprises the direct dyes mixture, color in time passing and change, this change is every kind of dyestuff for the different affinitys of keratin fiber and resists outside agent (as shampoo) and cause.

Target of the present invention provide do not have a direct dyes shortcoming can be used for the painted direct dyes of blast.Especially, one of target of the present invention provides direct dyes, and described direct dyes is still enough stable in the presence of oxidant and/or basifier, can obtain the blast and the dyeing of described fiber simultaneously.Another target of the present invention provides direct dyes, described direct dyes can change required tone, do not pass the problem that color changes in time and do not exist, and described direct dyes can make and treats that painted keratin fiber is dyed with the same dense with oxidation dye, it is to light, the same with described oxidation dye stable to the patience of vile weather, washing and sweat, and lasting.

The present invention has realized above-mentioned target, a theme of the present invention is the blast dye composite that comprises oxidant, basifier and cation mixed dye in suitable dyeing medium, the consumption of wherein said basifier is to make said composition pH greater than 7 amount, described cation mixed dye comprises the several chromophores that link together by connector (linker), at least two in these chromophores is different, and described chromophore shows at least one absorption maximum between 400-800nm.

Theme of the present invention also relates to the colouring method that uses said composition.

Another theme of the present invention relates to the present composition and is used for dyeing keratin fibres, and especially the purposes of human keratin fiber (as hair) relates in particular to the fastness (fastness) that obtains good anti-shampoo.

Especially, the present composition can obtain the blast and the dyeing of keratin fiber, and wherein this blast and dyeing are firm with respect to various outside agent, are firm for shampoo particularly.In addition, said composition can also avoid passing in time the problem that color changes.

Describedly be used for cation of the present invention to mix direct dyes be stable at lightening composition especially, this lightening composition comprises basifier (as ammonia) and/or oxidising agent (as hydrogen peroxide).Especially, when this mixed dye is used for non-lightening composition when (promptly not comprising basifier or any blast combination of agents thing), with when this mixed dye when comprising basifier (as ammonia) or oxidant (as aqueous hydrogen peroxide solution), or the compositions that comprises basifier and oxidant is simultaneously sent out the painted of tuft and is not changed basically when using together.

Among the present invention, be used for cation mixed dye of the present invention and be the dyestuff that its cationic charge can form the major part of the major part of chromophore and/or connector, or its cationic charge by substituent group at chromophore and/or the dyestuff that on connector, exists.

According to the present invention, term " chromophore " is meant the group derived from dyestuff, promptly derived from the group that the molecule of at least one absorption maximum is arranged in visible radiation scope (400-800nm), this absorb the Oxidation that requires not have formerly or with the combination of other any chemical substance.
