Abstract
A radiographic X-ray film comprising a polymer support. One or more silver halide emulsion layers are coated on each side of the support. A blue dye is contained within at least one of the polymer support or in an adjacent hydrophilic layer in a sufficient amount to result in a CIELAB measurement of L* less than or equal to 80 and b* less than or equal to −25. This configuration provides, after imaging and development, radiographic images having desirable visual contrast, image tone, b*, and image quality.
Claims16
A radiographic X-ray film comprising:
- a polymer support;
- having disposed on both sides thereof one or more silver halide emulsion layers that are the same or different wherein at least 50% of the total silver halide grain projected surface area comprises a tabular silver halide;
- and
- a blue dye contained within the polymer support, or within one or more additional hydrophilic layers or in both the polymer support and in the one or more additional hydrophilic layers in a sufficient amount to result in a CIELAB measurement of L* less than or equal to 80 and a b* value less than or equal to −25.
