ABSTRACT:
Prior to preparing an acid phosphor slurry for use in preparing dry photosensitive phosphor layers, particulate yttrium, lanthanum and/or gadolinium oxysulfide or vanadate phosphor is mixed with essentially water-insoluble particulate zinc phosphate in an aqueous medium. Then, the particle mixture is removed and dried. The invention includes both the novel method and the product of the novel method.
