Disclosed are weatherable multilayer articles. In one of its embodiments a multilayer article comprises: a coating layer comprising a block copolyestercarbonate comprising structural units derived from a 1,3-dihydroxybenzene and an aromatic dicarboxylic acid; a second layer comprising a polymer comprising carbonate structural units; and an adhesive tielayer. In one embodiment, the adhesive tielayer comprises a conjugated diene comprising a member selected from the group consisting of polystyrene-b-poly(isoprene)-b-polystyrene (S-I-S) block copolymers, and a blend of a S-I-S block copolymer with a polycarbonate. In another embodiment, the adhesive tielayer comprises a copolymer which has been modified by a polar functionalization agent. In yet another embodiment, the adhesive tielayer comprises a copolymer with structural units derived from an alkenyl aromatic compound and a conjugated diene comprising a member comprises polystyrene-b-poly(ethylene/butylene)-b-polystyrene.
