Beschreibung
Zusammenfassung:	An aqueous colloidal frozen gas black suspension comprises (wt.%): gas black (2-30), carbon black (0-40), dispersion supporting additive, biocide, and water, of zeta potential below -10 mV, surface tension higher than 50 nM/m and mean particle size less than 200 nm. Independent claims are included for: (1) a method of preparing the suspension by dispersion of the gas black, optionally the carbon black, and the dispersion supporting additive in water; (2) an ink containing the aqueous colloidal, frozen, and storage stable suspension. Wäßrige, kolloidale, gefrier- und lagerstabile Gasrußsuspension, bestehend aus 2 - 30 Gew.-% Gasruß, 0 - 40 Gew.-% Ruß, einem dispergierunterstützenden Additiv, einem Biozid und Wasser und deren Zetapotential kleiner -10 mV, die Oberflächenspannung größer 50 mN/m und die mittlere Teilchengröße kleiner 200 nm ist. Die wäßrige, kolloidale, gefrier- und lagerstabile Gasrußsuspension wird hergestellt, indem man den Gasruß und den Ruß gemeinsam mit dem dispergierunterstützenden Additiv und Biozid in Wasser dispergiert. Sie kann zur Herstellung von Tinten, Ink Jet Tinten, Lacken und Druckfarben verwendet werden.
