Abstract
Described is a scintillator screen that includes a supporting layer having a phosphor dispersed in a polymeric binder disposed on the supporting layer and a barrier layer disposed on the polymeric binder. The barrier layer includes a non-moisture absorbing polymer selected from the group consisting of polyethylene terephthalate, cellulose diacetate, ethylene vinyl acetate and polyvinyl butyraldehyde. The barrier layer has a thickness of less than 1 micron. An antistatic layer is disposed on the barrier layer. The antistatic layer includes poly(3,4-ethylenedixythiophene)-poly(styrene sulfonate) (PEDOT/PSS) dispersed in a polymer selected from the group consisting of a polyester and a polyurethane. The antistatic layer has a transparency of greater than 95 percent at a wavelength of from about 400 nm to 600 nm.
