Generally speaking, these processes only afford a slight improvement in the dyeing and fixation of the dyes when considered in relation to the already appreciable aflinity of the dyes for keratinic fibres at moderate temperature. Moreover, these methods considerably limit the range of dyestuffs which can be employed in hair dyeing. The
present invention obviates these disadvantages and in addition makes it possible to dye live or dead hair by means of dyestuffs "which have hithertobeen regarded as substantially unusable for that purpose. 1 r
It is an object of the present invention to provide a dyeing process in which an increased range of dyes can be employed, more particularly for dyeing hair, which promotesand accelerates the development of the shade and fixing of the dye, and which may be effected at the ambient temperature or at a moderately lowltemperature (e.g.
lower than 50 C) It is a further object of the invention to provide a dyeing process for hair which enables dyeing to be carried out very satisfactorily, from the viewpoint of rapidity and intensity, by means of dyes normallyhaving only very low afiinity, or even no afiinity, for hair under the aforesaid temperature conditions.
According to the present invention a composition for dyeing animalfibres comprises a solution of a direct dye in an aqueous organic solvent which is chemically indifierent with respect tothe dye and to the product to be dyed,
.the said solvent being completely miscible with water in the proportion in which it is present and having the general formula: R--(( -CH CH -OH in which Rrepresents a monovalent aliphatic hydrocarbon group having a straight or branched chain containing 4 to 5 carbonatoms and n is 1.
In the foregoing group R, thebranching may be either of the iso type (as for example inisoamyl alcohol).
Solvents of the aforesaid general formula include, for
example, the products sold under the trademark, Carbitol, and also condensation products of lower aliphatic alcohols with ethylene oxide. Preferred solvents are Z-butoxyethanol (,Butyl Cellosolve?) and the product of condensation of isoamyl alcohol with ethylene oxide in 'the proportion of 1 mole of isoamyl alcohol to .1 to 4, and J preferably 1.2 moles of ethylene oxide.
d ice 'I he above defined organic solvent is preferably used in the proportion of 5-20% by weight of the dyeing solution. However, larger or smaller proportions of solvent may be present depending upon the desired effect and provided that the solvent is wholly miscible with water. The inclusion of the solvent serves two purposes: on the one hand, it ensures, or increases the solubility of the dyestulf in the aqueous solution, and on the other hand, although the reason is not fully understood, the solvent appears to displace in favour of the fibre, the equilibrium which is established between the'dyestuff, the water in which it is dissolved and the fibre.
The expression direct dye is used herein to mean a dyestufi capable of,being directly applied to the fibre to give the final shade without involving the need of any chemical transformation such, for example, as oxidation, coupling or mo'rdanting of the fibre.
The direct dyes thus defined are divided into the following classes in accordance with the various preferred embodiments of the invention:
(A) Nitro dyes, such for example-as methyl-isoicramic acid and 1 hydroxy-2-amino-S-nitrobenzene;
(B) Azo dyes, such for example as those sold under the trade names:
Chrysoidine hydrochlori Edition, 1924) Supracide (Compagnie Frangaise des Matieres Colorantes) Supramine (Bayer) Kiton (Ciba) Cibacet (Ciba) and y Solacet (Imperial Chemical Industries Ltd.)
the last two to the extent to which they are actually azo dyes.
