摘要：
A reactive mixture for coating moldings by reaction injection molding includes at least 40% by weight of (meth)acrylates having at least two double bonds. The reactive mixture also includes at least one photoinitiator and at least one thermal initiator. Furthermore, a coated molding includes a molding obtainable by injection molding processes. The molding includes polymethyl methacrylate, polymethylmethacrylimide, styrene-acrylonitrile copolymer, styrene-maleic acid copolymer, polymethyl methacrylate copolymer, or a combination thereof. A coating is obtainable by polymerization of (meth)acrylates having at least two double bonds, the coating having an adhesive strength rating of not more than 1 according to the cross hatch test and a decrease in gloss at 20° after a scratch resistance test according to ASTM 1044 (12/05) (applied weight 500 g, number of cycles=100) of not more than 10%.
