Abstract
A multi-color photographic silver halide element has a total gelatin level on the imaging side of the support is less than 9000 mg/m2, and bulk gelatin-to-junk weight ratio for all of the light sensitive layers on the imaging side of the support is greater than 1.5. This weight ratio is defined by:
wherein Bgel is the total gelatin level for blue light sensitive layers, Bgel/junk is the gelatin-to-junk ratio for blue light sensitive layers, Rgel is the total gelatin level for red light sensitive layers, Rgel/junk is the gelatin-to-junk ratio for red light sensitive layers, Ggel is the total gelatin level for green light sensitive layers, and Ggel/junk is the gelatin-to-junk ratio for green light sensitive layers. The imaging layers can be thinned without undesirable loss in sensitometric properties and in increase in dust and dirt generation while providing reduced material costs and improving development properties.
