FIELD: chemistry.
SUBSTANCE: invention relates to a reactive mixture for coating moulded articles by reaction injection moulding. The reactive mixture contains at least 60 wt % (meth)acrylates with at least two double bonds, wherein content of at least one (meth)acrylate with three or more double bonds is at least 25 wt % of the weight of the reactive mixture. The reactive mixture contains at least one photoinitiator and at least one thermal initiator. Furthermore, the present invention describes a moulded article with a coating of the reactive mixture and a method for production thereof. The moulded article is obtained by reaction injection moulding and the moulded article contains at least one polymer selected from a group comprising polymethyl methacrylate, polymethacryl methylimide, a copolymer of styrene and acrylonitrile, a copolymer of styrene and maleic acid and copolymers of polymethyl methacrylate and a coating from the reactive mixture.
EFFECT: formation of a fast solidifying coating with scratch resistance and high strength of adhesion with the moulded article.
