Abstract: PROBLEM TO BE SOLVED: To provide a surface-modified silica which raises improved properties of a clear lacquer when it is used as a flatting agent for the lacquer.
SOLUTION: The surface of the precipitated silica is sufficiently modified by treatment with a polymer. The modified precipitated silica improves at least 20% of the transmittance of a clear lacquer containing 5 mass% above modified precipitated silica and having a refractive index n
D 20=1.4492 when compared with the same lacquer containing 5 mass% reference precipitated silica treated with a polyethylene wax.

Abstract: A precipitated silicic acid (I) has a surface that is modified by treatment with a polymer such that the transmission of a clear lacquer having a refractive index n D20 of 1.4492 and containing 5 wt.% of the modified silicic acid (I) is at least 20 % better than that of the same clear lacquer containing 5 wt.% of a reference precipitated silicic acid that has been treated with a polyethylene wax. An independent claim is included for a process for the production of the surface modified silicic acid (I) by: (a) precipitation of an alkali silicate solution with an acid under alkali to weakly acidic conditions; (b) further addition of an acid to adjust the pH to 7-2 to yield a silicic acid suspension; (c) filtering of the precipitated solid; and (d) drying of the solid by slow drying in a rotating tube dryer or plate drying or by means of rapid drying in a spray dryer or spinflash dryer to a residual moisture content of less than 10 % whereby the precipitated silicic acid is treated with a polymer to yield the silicic acid (I).
