Abstract

A color photographic recording material comprising at least one layer of which the primary sensitivity is blue, another layer of which the primary sensitivity is green and a further layer of which the primary sensitivity is red, gives satisfactory density graduations for details of high color saturation when a red sensitivity is produced in at least one layer, of which the primary sensitivity is green, and in at least one layer, of which the primary sensitivity is blue, the primary sensitivity being 8 to 25 DIN higher than the secondary sensitivity.
