Description

Composition for dyeing artificial hair of dolls

  changing color depending on the pH.

  The present invention relates to a novel

  for dyeing dolls' artificial hair, changing color according to the pH so that the color can be changed

  of said teinbxe, after it has been applied to the hair.

  We know that it has already been proposed in the application for

  vet French N '78 / 11.401 a composition for dyeing artificial hair dolls without color change and a device

  for its application on the hair. The composition according to this

  The anterior mande included a dye and a colloid and was

  in water or soluble in alcohol; it was applied to the

  yen of a hollow body device comprising a porous material

  for imbibition and controlled release.

  The present invention relates to a novel dyeing composition which is different from the prior composition by the nature of the ingredients it contains. This novel composition is advantageously applied dry by means of a similar device

  to that of the aforementioned French application.

  More specifically, it is recommended according to the invention a

  position for artificial hair dyeing dolls, changing

  color as a function of pH, removable by washing with water and

  born to be applied dry by means of a device of the body type

  hollow comprising a porous support for imbibition and release

  trèlée de liquide, said composition being characterized in that it contains: a) 0.5 to 2 parts by weight of a water-soluble dye selected from the group consisting of colored pH indicators which vary between pH5 and pH7, and preferably between pH5 and pH6,

  b) 1 to 2 parts by weight of a non-toxic dispersing agent

  preferably polyvinyl alcohol and c) water in addition to 100 parts by weight; and in that the pH of said composition is different from the turning pH

of the means a).

  After dry application of the composition according to the invention

  tion, all artificial hair is colored by brushing.

  More specifically, it is created by brushing said artificial hair superficial electrical charges, because of the mechanical friction of artificial hair with a brush. The head and the body of the doll having not the same density of superficial charges as the artificial hair, during the brushing, the adhesion of the dye is different; brushing distributes the dye evenly over the hair, while removing accidental deposits

  dye on the figure and the body of the doll.

  The child who has applied the dye according to the invention to the artificial hair of his doll, can modify the color by applying a dilute acid (which is preferably applied to

  dry by means of a device similar to that of the application of the

  said dyeing) then brushing to evenly distribute the new coloring. Preferably the means a) is a water-soluble, non-toxic dye used in the food industry and accepted by the

  national and international laws, and belonging to the family.

  the colorful pH indicators. In particular, the indicators

  pH 42.045, 42.051, 45.380 and 45.430 of the "Color Index".

  Where appropriate, it is possible to introduce into the composition of

  according to the invention, a means a ') selected from the group consisting of

  killed by water-soluble, non-toxic dyes whose color does not

  the pH, and their mixtures.

  The means a ') which is preferably chosen from among the

  Color Chart 16.255, 19.140, 42.090, 45.170 and their respective

  langes, will preferably be used from 0.5 to 5 parts in

  weight, in combination with a), b) and c).

  In practice, the pH of the composition comprising the means a), b) and c) and, where appropriate, a ') will be greater than the turning pH of the means a). To change the coloration of this dye, use a dilute mineral acid, and preferably HCI 0.01N - O, OOOOlN, because other mineral acids such as HNO3, H2SO4 can leave traces

  colored on the child's fingers.

  Other advantages and characteristics of the invention

  will be better understood with the following reading of examples of prepa-
