Patent ID: 7816442

Claim:
A lacquer, comprising: a surface-modified precipitated silica having a polymer on a surface thereof; wherein the polymer used to surface modify the said surface-modified silica is a polyorganosiloxane or a modified polyorganosiloxane; wherein the polymer is a polyorganosiloxane having the following structure: wherein Y=—OH, —OR or Y=H 5 C 2 —O—(C 2 H 4 O) m —, H 7 C 3 —O—(C 3 H 6 O) m — or R=alkyl, R 2 =alkyl, R 3 =alkyl, a=0-100, b is >/=1 to 100=0-100, c=0-100, d is >/=1 to 100=0-100, m=0-100 and k=0-100; or wherein the polymer is a polyorganosiloxane having the following structure: wherein R 1 is a methyl radical or and a sum of the units a=0 to 100, the sum of the units b=0 to 15, the ratio of methyl to alkoxy radicals for the radicals R 1 being less than 50:1 and b being ≧1 if a=0, and a≧5 if b=0.
