Process for making up or caring for keratin materials, comprising the application of compounds a and b, at least one of which is silicone-based

Cosmetic process for coating keratin materials, the process comprising the application to the said keratin materials:

• a. of at least one coat of a first composition;
• b. of at least one coat of a second composition;
• the first and/or second composition comprising at least one compound A and/or at least one compound B and optionally at least a catalyst or a peroxide, at least one of the compounds A and B being a silicone compound, provided that the compounds A and B, and the catalyst when present, or the peroxide, are not present together in the same compositions, the said compounds A and B being capable of reacting together via a hydrosilylation reaction or a condensation reaction, or a crosslinking reaction in the presence of a peroxide, when they are placed in contact with each other.

Process according to either of the preceding claims, characterized in that compounds A and B are capable of reacting via hydrosilylation.

Process according to one of the preceding claims, characterized in that compound A represents from 0.1% to 95%, preferably from 1% to 90% and better still from 5% to 80% by weight relative to the total weight of the composition comprising it and compound B represents from 0.1% to 95%, preferably from 1% to 90% and better still from 5% to 80% by weight relative to the total weight of the composition comprising it.

Process according to one of the preceding claims, characterized in that at least one of the first and second compositions comprises a liquid fatty phase comprising at least one organic solvent or oil chosen from volatile oils and non-volatile oils, and mixtures thereof.

Process according to the preceding claim, characterized in that the oil(s) is (are) present in a content ranging from 1% to 90% by weight and preferably from 5% to 50% by weight relative to the total weight of each composition.

Process according to any one of the preceding claims, characterized in that at least one of the first and second compositions comprises at least one dyestuff.

Process according to one of the preceding claims, characterized in that the first and second, and where appropriate third, compositions are lipstick compositions.

Cosmetic composition for coating keratin materials, comprising

• at least one compound A and at least one compound B, at least one of the compounds A and B being a silicone compound, the said compounds A and B being capable of reacting together via a hydrosilylation reaction or a condensation reaction, or a crosslinking reaction in the presence of a peroxide, when they are placed in contact with each other, and
• at least one pigment other than carbon black and iron oxides.

Kit for coating keratin materials, comprising at least one compound A and/or at least one compound B and optionally at least a catalyst or a peroxide, at least one of the compounds A and B being a silicone compound, provided that the compounds A and B, and the catalyst when present, or the peroxide, are not present together in the same compositions;

• the said compounds A and B being capable of reacting together via a hydrosilylation reaction or a condensation reaction, or a crosslinking reaction in the presence of a peroxide, when they are placed in contact with each other.
