Abstract
A process for non-migrating deposit of a composition for making up at least one keratinous material, such as, for example, a lipstick or a foundation, comprising including in said a-composition for making up at least one keratinous material at least one liquid continuous fatty phase comprising at least one dyestuff and at least one structuring polymer chosen from polymers of the following formula (I): in which n is an integer which represents the number of amide units such that the number of ester groups present in said at least one structuring polymer ranges from 10% to 50% of the total number of all said ester groups and all said amide groups comprised in said at least one structuring polymer, R1, which are identical or different, are each chosen from alkyl groups having at least 4 carbon atoms and alkenyl groups having at least 4 carbon atoms, R2, which are identical or different, are each chosen from C4 to C42 hydrocarbon-based groups with the proviso that least 50% of R2 are chosen from C30 to C42 hydrocarbon-based groups, R3, which are identical or different, are each chosen from C2 to C36 hydrocarbon-based groups, and R4, which are identical or different, are each chosen fro…
