Abstract
The present invention relates to photosensitive silver halide recording material with reduced pressure sensitivity. The occurrence of pressure marks can be minimized by protective layers with suitable additives. Other properties of the recording material, such as sensitivity, contrast, and clarity, are not affected adversely. Recording materials with protective layers containing polyolefin oxidates are largely insensitive to pressure marks and have low haze, high sensitivity, and high contrast. The invention's recording materials can be used in all fields of photographic and radiographic image production, especially in reproducing color images in steps preliminary to printing and in recording x-ray images for medical diagnostics.
