ABSTRACT:
An element for cleaning processing solutions contained in a radiographic film processor is disclosed. The element is comprised of a transparent film support and hydrophilic colloid layers coated on opposite sides of the film support. An infrared opacifying dye is contained within the element capable of reducing specular transmission through the element before, during and after processing to less than 50 percent, measured at a wavelength within the spectral region of from 850 to 1100 nm. A processing solution soluble colorant can be contained in one or more of the hydrophilic colloid layers.
