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.

Abstract:

Iadd. Method comprises applying a portion of initial slurry to a first substrate, spreading the initial slurry on the substrate, removing the excess slurry from the substrate, preparing a reconstituted slurry comprised of the removed excess slurry and a makeup slurry, and then dispensing a portion of reconstituted slurry onto a second substrate. As compared to the initial slurry, the makeup slurry has at least one of (1) a larger proportion of large particles, (2) a larger proportion of phosphor, (3) a greater binder/water ratio and (4) a smaller photosensitizer/binder ratio. Iaddend.
