Abstract: A method of coating a paper surface proceeds by applying a composition which is low in volatile organic compounds (VOC) or essentially free of VOC, wherein the composition is art least partially based on one or more partially or fully hydrolyzed and optionally condensed or co-condensed aminoalkyl- and oligosilyated-aminoalkyl-, alkoxy- or hydroxy-functional silicon compounds and the alcohol is at least partially removed from the composition

Abstract: 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.

Abstract: A composition has particularly good solubility in water. The composition includes an aminoalkyl-functional and/or oligo-silylated-aminoalkyl-, hydroxy-, and optionally alkoxy-functional silicon compound having reacted units of (A) an aminoalkylalkoxysilane; (B) a bis-silylated alkylamine; (C) a tri-silylated alkylamine; and (D) at least two of the alkylamines (A), (B), and (C), where the free alcohol content of the composition is less than or equal to 1% by weight, based on the composition.
