    • Light-sensitive silver halide photographic element comprising a support bearing at least a light-sensitive silver halide emulsion layer and at least a protective layer being further away from the support than every silver halide emulsion layer, said protective layer containing a gelatin having a viscosity lower than 20 milliPascal per seconds in 10 weight % aqueous solution at 40.degree. C., said gelatin being hardened with a carbamoyl pyridinium salt compound having the following formula: ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, each represents an alkyl group, an aryl group or an aralkyl group, or R.sub.1 and R.sub.2, together, constitute the atoms required to form a heterocyclic ring with the nitrogen atom to which they are bonded,R.sub.3 represents hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a carbamoyl group, or a ureido group, andR.sub.4 represents an alkylene group or a single chemical bond between the pyridinium nucleus and the --SO.sub.3 -- group.
    • 感光卤化银照相元件包括至少具有感光卤化银乳剂层的支撑体和至少一保护层,比保护层比每个卤化银乳剂层更远离支撑体,所述保护层含有粘度较低的明胶 在40℃下在10重量%水溶液中每秒20毫帕斯卡每秒,所述明胶用具有下式的氨基甲酰吡啶盐化合物硬化:其中R1和R2可以相同或不同,各自表示 烷基,芳基或芳烷基,或R 1和R 2一起构成与其键合的氮原子形成杂环所需的原子,R 3表示氢原子,卤素原子,烷基 ,烷氧基,氨基甲酰基或脲基,R4表示吡啶鎓核和-SO 3 - 基团之间的亚烷基或单个化学键。
