Abstract
A radiographic element is disclosed having a transparent film support and hydrophilic colloid layers including at least one silver halide emulsion layer coated on the support. 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.
Claims10
A radiographic element comprised of
- a transparent film support having first and second major faces and
- hydrophilic colloid layers coated on at least one of the first and second major faces including at least one radiation-sensitive silver halide emulsion layer,
- WHEREIN, 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.
