Abstract
The present invention relates to a cosmetic composition containing a cosmetically acceptable organic liquid medium and a film-forming linear ethylenic block polymer, the said polymer being such that, when it is in sufficient amount in the composition: the mean gloss at 20° of a deposit of the said composition, once spread onto a support, is greater than or equal to 30 out of 100, and the transfer index of the said composition is less than or equal to 40 out of 100.
