FIELD: chemistry.

SUBSTANCE: composite material system comprises a layer (a) of a polymer mixture containing or comprising (A) (co) polymer (meth) acrylate or a mixture of (co) polymers (meth) acrylate to at least 30 wt % based on total weight of A), formed from repeating units of methyl methacrylate. The polymer blend comprises B) a (co) polymer of styrene and maleic anhydride, wherein the proportion of repeating units of maleic anhydride is 10-30 wt % of the (co) polymer (B), and the proportion of repeating units of maleic anhydride in the layer (a) of the polymer mixture is 1-27 wt % of layer (a) of the polymer mixture. The composite system comprises (b) optionally one or more layers of optically transparent adhesive, layers of glass and/or optical films, (c) a layer of glass or polycarbonate. The invention also relates to a display that includes a composite material system.

EFFECT: reducing the deformation of the display, the shell of the touch screen display or glazing.
