Upon viewing following imagewise exposure and processing, the radiographic element exhibits a transparent blue appearance in areas of minimum density, at least a portion of the blue appearance being attributable to the presence in one or more of the hydrophilic colloid layers of at least one ionic linear condensation polymer containing an anthraquinone dye chromophore.
