Patent ID: 8318841

Claim:
A binder for air drying paint, based on metal oxide-containing nanoparticles with unsaturated organic branches, the binder comprising: at least one metal atom of the nanoparticle chemically bound to an organic branch with at least an unsaturated ethylenic functionality, wherein the binder includes the following chemical substructure: O 1.5 Si—(CH 2 ) p —NH—C(O)—(CH 2 ) q —(CH═CH) x —(CH 2 ) r —(CH═CH—CH 2 ) y —(CH 2 ) s —(CH═CH) z —(CH 2 ) t —CH 3 where p is an integer from 1 to 24 q, r, s, and t are each an integer from 0 to 21 x and z are each an integer from 0 to 4 and y is an integer from 0 to 6 and wherein oxygen atoms of the O 1.5 Si— are bound to metal atoms.
