  "abstract": "A cosmetic makeup composition contains in an appropriate cosmetically acceptable vehicle or carrier a colored pigment resulting from the salification reaction of a polymer having salified primary or secondary amine functions or quaternized tertiary amine functions and an acid dye, in free acid form or as a salt thereof, the acid dye being fixed on said polymer in an amount of at least 10 weight percent of the stoichiometric quantity. The compositions include lip rouges, cheek rouges, foundation creams and nail enamels.",
  "claims": [
    "1. In a cosmetic makeup composition for application to the lips, skin or nails comprising a cosmetically acceptable vehicle for the lips, skin or nails and a colored pigment, wherein the improvement comprises, as said colored pigment, 0.1 to 20 weight percent of a colored pigment resulting from the salification reaction in an aqueous medium of an azo dye selected from the group consisting of D and C Red 7, D and C Red 8, D and C Red 33, D and C Yellow 5, D and C Yellow 6, D and C Red 2 and D and C Red 4, with polyvinylamine hydrochloride, said colored pigment having a molecular weight between 1,000 and 200,000, said dye being attached to polyvinylamine hydrochloride by said salification reaction in an amount of at least 10 weight percent of the stoichiometric quantity.",
    "2. The cosmetic makeup composition of claim 1 wherein the azo dye is attached to said polyvinylamine hydrochloride via the salification reaction in an amount between 10 and 100 percent of the stoichiometric quantity.",
    "3. The cosmetic makeup composition of claim 1 which also contains a mineral pigment present in an amount ranging from 0.1 to 40 percent by weight based on the total weight of said composition said mineral pigment being selected from the group consisting of iron oxide, chrome oxide, ultramarine, titanium dioxide, manganese pyrophosphate or Prussian blue or a mixture thereof.",
    "4. The cosmetic makeup composition of claim 1 wherein said cosmetically acceptable vehicle is a fatty body comprising a cosmetically acceptable wax or a mixture of a cosmetically acceptable wax and a cosmetically acceptable oil, said makeup composition being in the form of a stick.",
    "5. The cosmetic makeup composition of claim 1 which also contains an effective amount of a nacreous agent selected from bismuth oxychloride, titanium mica or guanine crystals.",
    "6. The cosmetic makeup composition of claim 1 wherein said cosmetically acceptable vehicle is an emulsion consisting of an oil phase, an aqueous phase and an emulsifying agent, wherein based on the total weight of said composition, the oil phase represents from 1 to 98.8 weight percent thereof, the water phase represents from 1 to 98.8 weight percent thereof and the emulsifying agent represents from 0.1 to 30 weight percent thereof.",
    "7. The cosmetic makeup composition of claim 1 wherein said cosmetically acceptable vehicle is talc, kaolin, starch, polyethylene powder or polyamide powder, said makeup composition being in the form of a compact or loose powder."
