(JP2017506172) An elastomeric laminate for tires comprises at least two superimposed layers of elastomer. The first layer is composed of a composition based on at least one thermoplastic elastomer (TPE), said thermoplastic elastomer being a block copolymer comprising at least one optionally hydrogenated butadiene/styrene random copolymer-type elastomer block and at least one styrene-type thermoplastic block, at a content within a range extending from more than 50 to 100 phr (parts by weight per 100 parts by weight of elastomer). The second layer is composed of a composition based on at least one diene elastomer, the content of diene elastomer being within a range extending from more than 50 to 95 phr, and on at least one thermoplastic elastomer (TPE), said thermoplastic elastomer being a block copolymer comprising at least one optionally hydrogenated butadiene-styrene random copolymer-type elastomer block and at least one styrene-type thermoplastic block, at a content within a range extending from 5 to less than 50 phr.
