Abstract
An element capable of forming a silver image is disclosed containing insufficient radiation-sensitive silver halide grains to render the element detectable by an infrared sensor. The element has been modified to increase infrared specular density by the inclusion of, in a hydrophilic colloid dispersing medium, particles (a) being removable from the element during a rapid access processing cycle, (b) having a mean size of from 0.3 to 1.1 .mu.m and at least 0.1 .mu.m larger than the mean grain size of the radiation-sensitive grains, and (c) having an index of refraction at the wavelength of the infrared radiation that differs from the index of refraction of the hydrophilic colloid by at least 0.2.
