    摘要： The invention relates to the use of water-insoluble organopolysiloxane derivatives of the general formula (I) in which the radicals R1 are alkyl radicals, preferably having 1 to 4 carbon atoms or aryl radicals, but at least 80% of the radicals R1 are methyl radicals, and R2 at least once in the molecule has the definition (a) for defoaming aqueous media, especially printing inks and paints.
