SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To enhance the physical film properties of the silver halide photographic sensitive material in a developing solution. SOLUTION: The hydrophilic colloidal layer formed on a support is hardened by using vinylsulfone type hardening agent having a hydroxyl group in a weight ratio of (0.5-15):1 to the hardening agent represented by the formula in which M is an H or alkali metal atom. A calcium-freed gelatin is used as the hydrophilic colloid and the hydrophilic colloidal layers on the emulsion layer side of the support have a total thickness of 10-25μm.
