| 摘要 |
Aqueous, colloidal, freeze-resistant and storage-stable gas black suspension are disclosed containing 2-30 wt. % gas black, 0-40 wt. % carbon black, a dispersion-supporting additive, a biocide and water and having a zeta potential of less than -10 mV, a surface tension of greater than 50 mN/m and an average particle size of less than 200 nm. The aqueous, colloidal, freeze-resistant and storage-stable gas black suspension is produced by dispersing the gas black and the carbon black in water together with the dispersion-supporting additive and biocide. Inks, ink-jet inks, lacquers and printing inks can be made from these suspensions.
