    摘要： Dispersion comprising, in addition to water, from 0.5 to 20% by weight of hydrophobic silica, 0.01 to 10% by weight of a gelling or viscosity-increasing additive, 0.1 to 1% by weight of a preservative and 0 to 1% by weight of a surface-active agent, which comprises, as additional component, at least one insecticide and/or acaricide. It is prepared by dispersing the individual components, successively or together, in the water and, in this connection, deaerating the individual components before and/or during the addition or deaerating the dispersion during the individual dispersing stages. The dispersion can be used as insecticide or acaricide.

    摘要： Dispersion comprising metal oxide particles, in which a) the metal oxide particles a1) are selected from one or more oxides from the group consisting of titanium dioxide, cerium oxide, zinc oxide and zirconium dioxide, a2) are present in the dispersion with a proportion of at least 25% by weight, a3) have a mean aggregate diameter of 20 to 120 nm, and b) the liquid phase comprises b1) 90 to 99.5% by weight of one or more alkanols C
    n H
    2n+1 OH where n = 2 to 4, b2) 0.5 to 10% by weight of one or more a,ß-unsaturated carboxylic acids having 4 to 12 carbon atoms, b3) 0 to 2% by weight of one or more alkanediols HO(CH
    2 )
    x OH where x = 2 to 4, b4) a maximum of 5% by weight of water and b5) a maximum of 2% by weight, in total, of dispersing additives from the group consisting of polyoxyethylenated alkyl ether phosphates, polyoxyethylenated aryl ether phosphates; alkylolammonium salts of block copolymers having acidic groups; polyalkylene glycols, polyalkylene imines, polyalkylene alcohols. Use of the dispersion for production of dye solar cells.
