Abstract (en)
Carrier particles having a coating comprising a polycondensation network containing a chemical compound selected from the group consisting of a monomeric polyfunctional organosilane, an hydrolysis product of a monomeric polyfunctional organosilane, a reaction product of a monomeric polyfunctional organosilane with an organosilane containing an hetero-atom and a reaction product of a monomeric polyfunctional organosilane with an alkoxide, characterised in that the coating further comprises between 5 % and 50%, by weight, both limits included, of a polymeric compound not containing silicon atoms.
