摘要:
A multi-layered product in the form of sheet, film or a three dimensional molded article is disclosed. The product comprised a first layer (A) having a thickness of 1 μm to 2 mm containing polyalkyl (meth)acrylate and 0.01 to 20 percent relative to the weight of said first layer of a UV stabilizer and a second layer (B) that contains polycarbonate. The stabilizer conforms to formula (I) wherein X denotes OR1; OCH2CH2OR1; OCH2CH(OH)CH2OR1 or OCH(R2)COOR3, R1 is branched or unbranched C1-C13 alkyl, C2-C20 alkenyl, C6-C12 aryl or —CO—C1-C18 alkyl, R2 is H or branched or unbranched C1-C8 alkyl, and R3 is C1-C12 alkyl; C2-C12alkenyl or C5-C6 cycloalky. The product is characterized by its optical transparency and resistance to yellowing and is most suitable for glazing applications.
