Zusammenfassung:Core-shell particles and processes for producing the same. Where the core-shell particles include a core (B) and a shell (D). The core (B) includes a thermoplastic polyester (C) with a melting range of lower than 160° C. and the shell (D) includes partially water-wettable particles (E) of metal oxide. Where the partially water-wettable particles (E) have a methanol value of less than 30 and the metal content of the core-shell particles (A) is at least 2.5% by weight.
