Abstract

A method of colouring fibrous materials (e.g. artificial dolls hair) comprises applying a solution of an indicator (e.g. phenolphthalein) in a volatile solvent to the material; allowing the solvent to evaporate and subsequently spraying the fibrous material with an appropriate solution so as to cause the indicator to change colour. The indicator solution may be applied in liquid or gel form or via a fibre-tipped pen.

Description

-Title: Colouring Artificial Hair The present invention relates to a method of colouring a fibrous material, in particular artificial hair e.g. Dolls Hair. The invention also provides a kit for use in such a method.
In accordance with the present invention, there is provided a method of colouring fibrous material comprising applying a solution of an indicator in a volatile solvent to the fibrous material, allowing the solvent to evaporate and subsequently spraying the fibrous material with an appropriate solution so as to cause the indicator to change colour.
Preferably, the fibrous material is artificial hair such as dolls hair.
It is also preferred that the indicator is an acid- based indicator and is conveniently a phthalein e.g.
phenolphthalein.
The indicator and solvent can be provided in liquid form and be contained in a fibre tipped pen for application directly to the fibrous material. The solution of the indicator can also be provided in liquid form in which it can,be sprayed or combed into the fibrous material or alternatively inthe form of a gl.
The present invention also provides a kit for performing the method comprising a first pack comprising an indicator disolved in a volatile solvent and a second pack comprising a solution of a compound which will cause the indicator to change colour.
There will now be described by way of example a method according to one embodiment of the present invention.
The method utilises a first solution (solution A) comprising a mixture of phenolphthalein, N propanol and biocide (Bannernol M, Lankropol K02/Manox and Acticide BX) in water and a second solution (solution B) comprising sodium carbonate 1.5 wtt, triethanolanine 1.5 vol % and biocide (Methyl paraben 0.1 wt % amd Propylparaben 0.4 wt t) In deionised water.
Solution A is applied to a dolls hair by means of a felt tip pen and allowed to dry. In this condition, the phenolphthalein is colourless and so no colour is imparted to the hair. Solution B is then sprayed onto the hair, the alkaline nature of the solution causing the indicator to become a pinky red colour and thus colouring the hair.
Ph,thålein indicators such as phenolphthalein tend to lose their colour'after short time of about 15 to.20 minutes but the colour can.be restored by a further application of solution B. The indicator can be removed from the hair by washing with water.
Any suitable indicator can be used for solution A according to the colour change required. The compound in solution B must be selected accordingly and in some cases a further colour change or the reversal of the colour change might be achieved by use of a further solution of an acid for example.
While the description above shows only a change from colourless to a pink colour, appropriate selection of the indicator can be used to achieve a change between two particular colours and it will be appreciated that the solvents, indicators and activating compounds can be selected according to the desired colour combinations required.

Claims (10)

Claims
1 A method of colouring fibrous material comprising applying a solution of an indicator in a volatile solvent to the material; allowing the solvent to evaporate and subsequently spraying the fibrous material with an appropriate solution so as to cause the indicator to change colour.
2 A method as claimed in claim 1, wherein the indicator is an acid-base indicator.
3 A method as claimed in claim 2, wherein the indicator is a phthalein indicator.
4 A method as claimed in claim 3, wherein the indicator is phenolphthalein.
5 A method as claimed in any preceding claim, wherein the indicator and solvent are provided in a felt tip pen for application to the fibrous material.
6 A method as claimed in any of claims 1-4, wherein the indicator is provided in a form which can be sprayed or combed onto the fibrous material or is in the form of a gel.
7 A kit for.colouring fibrous material comprising a solution of an indicator in a volatile solvent in an applicator and a spray containing a solution of appropriate composition to cause the indicator to change colour.
8 A kit as claimed in claim 7 wherein the applicator is a felt tip pen.
9 A method which is substantially as herein described.
10 A kit which is substantially as herein described.
