  • Patent number: 8877332
    Abstract: The use of a mixture with spherical metal particles and metal flakes as a laser marking or laser weldability agent in a plastic, wherein the particle size distribution of the spherical metal particles and metal flakes, as determined with laser granulometry, in the form of the volume-averaged cumulative undersize particle size distribution, has a Dmixture, 90 value of <100 ?m and a Dmixture, 50 <60 ?m. Further, a masterbatch comprising a mixture with spherical metal particles and metal flakes also can be used. Additionally, the present subject matter may further relate to a laser markable and/or a laser weldable plastic comprising a mixture with spherical metal particles and metal flakes.
