    摘要： The present invention relates to a stable composition of water-soluble organosiloxanes obtained by reacting a) a water-soluble amino-functional alkoxysilane with at least one water-insoluble alkenyl-functional alkoxysilane b) by adding water to form a mixture, and c) removing the alcohol formed during step b) from the mixture, where the amino-functional alkoxysilane and the water are used in the reaction at least in amounts such that substantially all of the alkoxy groups of the water-insoluble silane can react and such that when a resulting composition is diluted with water, essentially no alcohol is liberated by hydrolysis, and the composition, during an/or after the reaction, has a pH of from 2 to 6, the pH being preferably adjusted by adding an organic or inorganic, optionally aqueous, acid. In addition, the present invention discloses a process for the preparation of such a composition and also its use.

    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.
