A multilayer structure that includes a substrate layer containing a mixture containing one or more copolymers that include polymerized residues from one or more styrenic monomers and one or more C1-C32 linear, branched, or cyclic alkyl (meth) acrylate monomers and/or maleic-type monomers and one or more elastomeric materials; and a reflective film layer coated on a surface of the substrate layer. The multilayer structure can be used as an- optical storage medium. La présente invention concerne une structure multicouche qui comprend une couche de substrat contenant un mélange contenant un ou plusieurs copolymères qui comprennent des résidus polymérisés d'un ou de plusieurs monomères styréniques et un ou plusieurs monomères de (méth)acrylate d'alkyle en C1 à C32 linéaire, ramifié ou cyclique et/ou des monomères de type maléique et un ou plusieurs matériaux élastomériques ; et une couche de pellicule réfléchissante recouvrant une surface de la couche de substrat. La structure multicouche peut être utilisée comme support d'enregistrement optique.
