The present invention relates to a plastics composition which comprises at least one platelet-shaped metal pigment from a range of from 0.01 to 25 wt.-%, at least one light stabilizer from a range of from 0.01 to 10 wt.-% and at least one antioxidant from a range of from 0.01 to 2 wt.-%, in each case relative to the proportion by weight of the plastics composition.

Plastics composition comprising at least one metal pigment, method for production and use thereof

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 Dvalue of &#x3c;100 &#x3bc;m and a D&#x3c;60 &#x3bc;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.

Use of a mixture comprising spherical metal particles and metal flakes as laser-marking or laser-weldability agents and laser markable and/or laser weldable plastic

The invention relates to the use of spherical metal particles, which are free of antimony and/or antimony-containing compounds, as a laser marking agent or laser weldability agent in a plastic, wherein the particle size distribution of the spherical metal particles, as determined by means of laser granulometry, in the form of the volume-averaged cumulative undersize particle size distribution, has a Dvalue of &#x3c;110 &#x3bc;m, a Dvalue of &#x3c;75 &#x3bc;m, and a D&#x3c;45 &#x3bc;m. The invention further relates to a laser-markable and/or laser-weldable plastic which a laser marking agent consisting of spherical metal particles, which are free of antimony and/or antimony-containing compounds, wherein the particle size distribution of the spherical metal particles, as determined by means of laser granulometry, in the form of the volume-averaged cumulative undersize particle size distribution, has a Dvalue of &#x3c;110 &#x3bc;m, a Dvalue of &#x3c;75 &#x3bc;m, and a D&#x3c;45 &#x3bc;m.

Use of spherical metal particles as laser-marking or laser-weldability agents, and laser-markable and/or laser-weldable plastic
