ABSTRACT:
A process is disclosed for binding pigment particles to phosphor particles which involves forming an aqueous slurry of phosphor particles, pigment particles, and a binding agent which can be latex polymers or copolymers, the binding agent having a glass transition temperature of greater than about 20.degree. C. and agitating the slurry, separating the solids from the resulting liquor, and drying the solids at a temperature above the Minimum Film Formation Temperature of the latex to produce the phosphor particles wherein the pigment particles are bonded to them.
