The present invention relates to colored compositions used as coatings for tires. The present invention relates to a tire having an outer rubber surface based at least in part on essentially unsaturated diene elastomers, which is covered with the colored coating. The coating comprises at least one layer in contact with the air and has a composition comprising a majority proportion of polyurethane produced from a polyol selected from the group consisting of aliphatic polyethers, aliphatic polyesters, polyethers having a main chain that is semi-aromatic and polyesters having a main chain that is semi-aromatic, and flakes of aluminum in an amount of between 20 and 150 parts of flakes per hundred parts of dry polyurethane, phr, wherein the bond between the elastomer and the polyurethane being produced due to the polar functions. The present invention also relates to methods of producing the composition and the tire comprising the composition. |
