Abstract
The present invention is drawn to a latex-encapsulated particulate, comprising a particulate from 30 nm to 150 nm in size, and a latex at least partially encapsulating the particulate. The latex can have a surface dielectric constant from 2.0 to 3.0 at room temperature, and the latex-encapsulated particulate can have a bulk density from 0.90 g/cm3 to 2.0 g/cm3.
Claims38
A latex-encapsulated particulate, comprising:
- (a) a particulate from 30 nm to 150 nm in size;
- and
- (b) a latex at least partially encapsulating the particulate, said latex having a surface dielectric constant from 2.0 to 3.0 at room temperature, and said latex-encapsulated particulate having a bulk density from 0.90 g/cm3 to 2.0 g/cm3.
A latex-encapsulated particulate, comprising:
- (a) a particulate from 30 nm to 150 nm in size;
- (b) a latex at least partially encapsulating the particulate;
- and
- (c) a reactive surfactant covalently attached to the surface of the latex, said latex-encapsulated particulate having a bulk density of from 0.90 g/cm3 to 2.0 g/cm3 and said latex having a surface dielectric constant from 2.0 to 3.0.
