1. An aqueous particle dispersion comprising a polymer and a Si—O-containing moiety, wherein the Si—O-containing moiety comprises a structure of Formula II and is linked to the polymer,

OG Complex Work Unit Chemistry
wherein
R5, R6, and R7 each independently represent a substituted or unsubstituted alkyl, aryl, aralkyl, or heteroalkyl group;
L represents a divalent or multivalent linking group comprising no more than eight carbon atoms;
X is NH, NR, or O;
Y is NH, NR, O, or a carbonyl moiety; and
R is a substituted or unsubstituted alkyl, aryl, aralkyl, or heteroalkyl group, and
wherein the particle dispersion is obtainable by adding a Si—O-containing moiety precursor to an organic solvent during the preparation of the particle dispersion.
