The invention relates to a cosmetic makeup and/or care composition for
keratin fibres and/or the skin, comprising at least one particle
dispersion comprising one at least partially internal phase of supple type
comprising at least one supple polymer, with a glass transition
temperature of less than or equal to 60.degree. C. and one at least
partially external phase of rigid type which is an amorphous material
having a glass transition temperature of greater than 60.degree. C. and
which is such that the supple polymer is at least partially attached by
chemical grafting onto the said phase. The invention also relates to the
use of at least such a particle dispersion for improving the level of
comfort and staying power of cosmetic compositions comprising it.
