Abstract:
The invention relates to a multilayer product comprising a first layer (A), a second layer (B), a third layer (C), and a fourth layer (D). The first layer (A) is a scratch-resistant protective layer having a minimum extinction of 0.3 at 340 nm, the second layer (B) is an alkyl acrylate layer having a minimum extinction of 2 at 340 nm, and the third layer (C) and the fourth layer (D) contain a UV-stabilized polycarbonate. The invention also relates to a method for manufacturing the multilayer product.
