摘要： Modified pearl luster pigments for waterborn coating systems, based on a platelet-form substrate coated with metal oxides and, located on the topmost metal oxide layer, a top layer consisting of at least two oxides and/or mixed oxides from the group consisting of silicon dioxide, aluminium oxide, cerium oxide, titanium oxide and zirconium oxide, and on a water-based oligomeric silane system. The oligomeric silane system can be described, for example, by the following approximate structure: [HO[Si(A)(OH)z(CH3)1−zO]a[Si(B)(OH)y(CH3)1−yO]b[Si(E)(OH)w(CH3)1−wO]c[Si(D)(OH)v(CH3)1−vO]dH].(HX)e (IX) where A=aminoalkyl radical derived from the general formula V, B=glycidyl ether alkyl radical derived from the general formula VI, E=acryloxyalkyl or methacryloxyalkyl radical of the general formula VII, D=alkyl radical of the general formula VIII, HX=monobasic acid, where X=inorganic or organic acid radical such as, for example, chloride, nitrate, formate, acetate, v is equal to 0 or 1 and w is equal to 0 or 1 and y is equal to 0 or 1 and z is equal to 0 or 1 and a+b+c+d≧4 and a≦e≦2a, where 0≦a/(b+c+d)≦3, especially for a/(b+c+d) equal to 0 if a=0 and/or c equal to d equal to 0 and b≧1 and also for 0.5≦a/(b+c+d)≦3.
