Patent ID: 7553889

Claim:
A coating composition, comprising: a coating material; and a matting agent, comprising: a surface-modified precipitated silica having a polymer on a surface thereof; wherein said surface-modified precipitated silica improves a transmission of a clear coating material, having a refractive index of n D 20=1.4492 and containing 5% by weight of said surface-modified precipitated silica, by at least 20%, in comparison to said clear coating material containing 5% by weight of a reference precipitated silica surface treated with a polyethylene wax; 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, c=0-100, d is >/=1 to 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 =0, and a≧5 if b=0.
