Abstract
Cosmetic compositions for make-up containing acrylic comb copolymers having the advantage of increasing the intensity of the color produced by these compositions when they are applied to the skin or to keratin derivatives such as the hair or the eyelashes. Not only are the aesthetic properties conferred by these compositions thus improved, but their useful life is also increased, since they allow access to the desired shade (and good intensity) right from the first application.
