    • 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.
    • 用于防水涂料体系的改性珍珠光泽颜料,基于涂覆有金属氧化物的片状基材,并且位于最上面的金属氧化物层上,由至少两种由硅组成的组的氧化物和/或混合氧化物组成的顶层 二氧化硅,氧化铝,氧化铈,氧化钛和氧化锆,以及水性低聚硅烷体系。 低聚硅烷体系可以例如通过以下近似结构来描述:其中A =衍生自通式V的氨基烷基,B =衍生自通式VI的缩水甘油醚烷基,E =一般的丙烯酰氧基烷基或甲基丙烯酰氧基烷基 式VII,D =通式VIII的烷基,HX =一元酸,其中X =无机或有机酸基,例如氯化物,硝酸盐,甲酸盐,乙酸盐,v等于0或1,w为 等于0或1,y等于0或1,z等于0或1,a + b + c + d> = 4,a <= e <= 2a,其中0 <= a /(b + c + d)<= 3,特别是对于a = 0和/或c等于d等于0且b> = 1而且对于0.5 <= a /( b + c + d)<= 3。
