Use of mixtures of polymethyl methacrylate and styrene- acrylonitrile copolymers for the production of laser-inscribed moldings

摘要

Transparent molded articles having a high-contrast laser inscription thereon are produced from a polymer mixture consisting of P PA) from 40 to 99% by weight of a polymer of an alkyl ester of (meth) acrylic acid,PPB) from 1 to 50% by weight of a copolymer of styrene and acrylonitrile having an acrylonitrile content of from 8 to 30% by weight,PPC) from 0 to 50% by weight of rubber particles, andPPD) from 0 to 20% by weight of additives and processing auxiliaries, by preparing a transparent molded article from the polymer mixture, and exposing the transparent molded article to laser radiation.
