ABSTRACT:
Method comprises adsorbing colloidal particles of a latex onto phosphor particles, providing filter particles in a liquid medium, optionally adsorbing colloidal particles of a latex onto the filter particles and combining the phosphor particles and filter particles into a single mixture. The foregoing steps, which are conducted in aqueous media, may be carried out in any order. Thereafter, the combined mixture of phosphor particles with adsorbed colloidal particles thereon and filter particles is coagulated while in an aqueous medium.
