Abstract
The present invention relates to a process for preparing a colored lamellar composition that may provide a wide range of colors. The process includes the steps of dispersing a colorant in a hydrocarbon, grinding the dispersed colorant to a particle size of less than about 1 micron (μm), and spraying the colorant onto a lamellar substrate to provide the colored lamellar composition while mixing and heating the lamellar composition to remove the hydrocarbon.
