ABSTRACT:
A layer arrangement comprising, at least in a binderless layer thereof, one or more vapor deposited pigments like the preferred nanocrystalline β-Cu-phthalocyanine nanocrystalline dye compound has been disclosed, wherein said layer arrangement is, in a preferred embodiment a photostimulable phosphor plate or panel having a binderless needle-shaped photostimulable alkali metal phosphor, and, more preferably, a CsBr:Eu2+phosphor, showing besides a high image definition, an excellent preservation of color stability; and wherein the thus produced binderless photostimulable phosphor screen is overcoated with a strong protective layer in order to provide ability for easy transport through a scanning module, without jamming, in a diagnostic radiographic image reading system.
