An elastomer laminate comprising three layers is provided. The first layer consists of a diene rubber composition comprising a first elastomer matrix. The second layer consists of a diene rubber composition comprising a second elastomer matrix, which second elastomer matrix comprises a second terpolymeric elastomer of ethylene, of an α-olefin and of a non-conjugated diene and contains more than 10% by weight of diene units. The third layer consists of a diene rubber composition comprising a third diene elastomer having a content by weight of diene units of greater than 50%. The second layer is arranged between the first layer and the third layer. Such a laminate has good resistance to separation of the layers which constitute it.
