| 摘要 |
The invention relates to the use of a mixture with spherical metal particles and metal flakes as a laser marking agent or laser weldability agent in a plastic, wherein the particle size distribution of the spherical metal particles and of the metal flakes in the mixture, as determined by means of laser granulometry, in the form of the volume-averaged cumulative undersize particle size distribution, has a Dmixture, 90 value of <100 μm and a Dmixture, 50<60 μm. The invention further relates to a masterbatch which comprises a mixture with spherical metal particles and metal flakes. The invention additionally relates to a laser-markable and/or laser-weldable plastic which comprises a mixture with spherical metal particles and metal flakes. |
