| 摘要 |
The present invention relates to a reactive mixture for coating molded objects by means of reaction injection molding comprising at least 40% by weight of 5 (meth) acrylates with at least two double bonds, wherein the reactive mixture comprises at least one photoinitiator and at least one thermal initiator. Furthermore, the present invention describes a coated molded object comprising a molded object which is obtainable by injection molding and which includes at least one polymer selected from the group comprising poly(methyl methacrylate), poly(methacryl methylimide), styrene-acrylonitrile copolymer, styrene-maleic acid copolymer, and poly(methyl methacrylate) copolymer, and a coating, which is obtainable by the polymerization of (meth) acrylates with at least two double bonds, wherein the coating has an adhesive strength rating of not more than 1 according to the cross-cut test and a decrease in gloss at 20Â °ree;C according to a scratch-resistance test according to ASTM 1044 (12/05) (load of 500 g, number of cycles = 100) of not more than 10%. |
