Abstract: 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.
