DISPERSION, STREICHFARBE UND AUFNAHMEMEDIUM

摘要

The stable, aqueous dispersion has between 20 and 80 Gew.-per cent related to the total quantity of the dispersion, metal and/or metalloid oxide powder present in the form of aggregates of primary particles. The powder has at least two types of powder with the same sign of surface charge for a given pH value and a zeta potential causing an electrostatic repulsion between the particles greater than the van der Waals attraction of the powder. The stable, aqueous dispersion has between 20 and 80 Gew.-per cent related to the total quantity of the dispersion, metal and/or metalloid oxide powder present in the form of aggregates of primary particles in the dispersion, where the mean diameter of the aggregate is between 10 and 300 nm and the mean diameter of the primary particles is between 5 and 50 nm. The powder has at least two types of powder with the same sign of surface charge for a given pH value and a zeta potential causing an electrostatic repulsion between the particles greater than the van der Waals attraction of the powder. AN Independent claim is also included for the following: a brushing-on color and a recording medium.
