摘要： The present invention relates to a process for preparing aqueous hydrolysates of aminoalkyltrialkoxysilanes by (a) initially charging water, optionally heating, (b) adding hydrolysable silanes consisting of at least one aminoalkyltrialkoxysilane in an amount which provides a molar ratio of water to total amount of aminoalkyltrialkoxysilane of 10.5 to 20, and (c) distilling off the alkyl alcohol formed in the reaction, wherein the solids content in an aqueous composition thus prepared is 30% to 55% by weight, based on the composition, and the aqueous solution has a total content of free and bound alkyl alcohol of not more than 1% by weight, based on the composition.

摘要： The invention relates to novel quaternary amino alcohol functional organosilicon compounds, aqueous compositions containing the latter, and a method for their production, in particular in the form of oligomers and polymers which can be present in the partially or fully hydrolyzed form and are in particular water-soluble. The compositions comprise only an extremely small portion of VOCs. The invention further relates to their use, preferably in the production of inkjet photographic papers.
