Beschreibung
Zusammenfassung:	The disclosure is directed to a method for preparing an adhesive composition, in which an aqueous phase comprising a modified colloidal silica is mixed with an organic phase comprising one or more monomers in the presence of an initiator, wherein conditions are maintained such that polymerisation of the one or more monomers occurs to form an aqueous polymeric dispersion, wherein;(i) the aqueous polymeric dispersion comprises polymer particles with protective colloid on their surface;(ii) the modified colloidal silica comprises colloidal silica particles with at least one surface-bound hydrophilic organosilane moiety and/or comprises colloidal silica particles with at least one additional element on its surface, the element being able formally to adopt a +3 or +4 oxidation state; and(iii) the initiator is at least partially soluble in water.
