Abstract
A radiographic element is disclosed having a support capable of transmitting blue light and, coated on each of two opposite major faces of said support, a silver halide emulsion layer capable of forming a latent image in response to exposure to blue light. Interposed between at least one of the latent image forming emulsion layers and the support is a blue absorbing silver iodide emulsion layer exhibiting at temperatures below 25.degree. C. an absorption transition wavelength that is bathochromically displaced by at least 20 nm as compared to the absorption transition wavelength of .beta. phase silver iodide.
