ABSTRACT:
The invention concerns glass microbubbles having an inorganic thin-film coating not exceeding about 10 nm in thickness, especially a coating of a metal, a metalloid, or an alloy thereof. When dispersed throughout a matrix such as a polymer, the coated glass microbubbles can afford surprisingly good hiding power while also imparting esthetically pleasing colors to otherwise transparent articles.
