A radiographic phosphor panel exhibits provides increased photospeed and image sharpness in exposed radiographic films. This panel includes a phosphor layer that transmits actinic radiation in a range that is reflected by a transparent, polymeric multi-layer reflector used as part of a support. This polymeric multi-layer reflector exhibits a different level of reflectance of light depending upon the angle of light incidence that is greater than 0 and up to and including 90 degrees. On the opposing surface of the reflector is a light absorbing substrate.
