Abstract
A particle composition includes one or more particles comprising a pigment material and a polymeric coating layer at least partially surrounding the pigment particle and stanchions for particle to particle bridging extending from the coating layer. The particle composition can further include discrete particle separators between the particles of pigment material. The stanchions and particle separators contribute to a reduced particle density in the particle composition.
