发明名称 VISCOELASTIC MEMBER WITH POLYMER LAYER CONTAINING LOCALIZED ELASTOMER
摘要 <p>Provided is a viscoelastic article which exerts different properties between one surface and the other surface thereof, which has a transparent appearance, and which less causes staining of objects to which the viscoelastic article is adopted. The viscoelastic article is an article having a multilayer structure including a polymer layer, and a monomer-absorptive layer capable of absorbing at least one of monomer component(s) constituting the polymer, in which the polymer layer is a polymer layer containing an elastomer unevenly distributed and enriched at an interface, or in the vicinity thereof, opposite to the monomer-absorptive layer. The viscoelastic article may further include a cover film on the polymer layer containing the unevenly distributed elastomer on an opposite surface to the monomer-absorptive layer. The vicinity of the interface opposite to the monomer-absorptive layer is preferably a region ranging from the interface opposite to the other interface with the monomer-absorptive layer and occupying, in a thickness direction, 50% or less of the total thickness.</p>
