Aseries of film coatings was prepared from an X-ray type emulsion and dried at temperatures ranging from 14 to 30°C. Both the degree of triple-helix formation based on diITerential scanning calorimetry and the size of long wavelength X-ray scatterers increased with decreasing drying temperature. These structure changes Improved film physical properties, but also, Put greater stress on the grains which caused increased fog. Avery sensitive X-ray diffraction technique, high-angle Bragg diffractiOn, demonstrated that this greater stress caused a more inhomogeneous silver halide lattice spacing.
