Abstract

---

Laser marking of plastic material is achieved by incorporating into the plastic a laser marking particulate additive having a particle size of less than 100 nm. A mixed oxide particle of tin and antimony having a particle size of 10 70 nm is useful as a laser marking additive when using a YAG laser. A metallic powder can further be added to improve marking contrast.
