| 摘要 |
The invention relates to novel molding compounds based on partially crystalline technical thermoplastics, which allow to produce laser-markable molded articles having increased quality of marking. The molding compounds are characterized by comprising, in a polymer matrix (A) microscale or nanoscale primary particles of photosensitive compounds having a plurality of cations (B) and/or nanoscale primary particles of photosensitizing oxides (C) and optionally other additives (D). The invention also relates to molded articles that are produced from the inventive laser-markable molding compounds, to a method for laser marking and to the use of selected additives for laser marking.
