Abstract:
A method of making a color photothermographic element comprising a red-light-sensitive silver-halide layer unit, a green-light-sensitive silver-halide layer unit, and a blue-light-sensitive silver-halide layer unit, each layer unit further comprising a light-sensitive silver-halide emulsion, a gelatin binder, at least one essentially non-light sensitive organic silver salt that functions as an oxidizing agent for the purpose of donating silver during dry thermal development, and a developing-agent precursor, which element is developed by heating to a temperature of 120 to 180Â° C., which method comprisesannealing by heating at least one imaging layer in the color photothermographic element such that the surface of the element attains a temperature of at least 55Â° C. for at least 2 seconds at a relative humidity of less than 50%, wherein the annealing occurs after the imaging layer is substantially dried but before image capture.
