  • Patent number: 4683007
    Abstract: Dispersions of titanium dioxide pigments with improved long-term resistance to pigment settling and precipitation are disclosed. The pigment dispersions are formed by chemically grafting vinyl and/or acrylic polymers to nitrocellulose in dispersions of nitrocellulose and titanium dioxide pigments. Nitrocellulose forms a loose association with titanium dioxide in dispersion. The chemical grafting improves the precipitation and settling resistance of nitrocellulose, and thus the precipitation and settling resistance of the associated titanium dioxide.
