    • A silver halide photographic material is described, which contains the compound represented by the following formula (I): wherein R1 represents a substituted or unsubstituted alkylene group having from 1 to 5 carbon atoms; X represents a water-soluble group; and R represents a substituted or unsubstituted alkyl group having the sum total of from 14 to 40 carbon atoms, an alkenyl group, an aryl group, an alkoxyl group, —NR3R4 (R3 and R4 each independently represents an alkyl group having from I to 40 carbon atoms, a hydrogen atom, or an aryl group), a bicycloalkyl group, a bicycloalkenyl group, a cycloalkyl group, a cycloalkenyl group or a heterocyclic group, provided that when X represents a quaternary ammonium salt structure, R2 does not represent an alkyl group having from 14 to 17 carbon atoms.
    • 描述了卤化银照相材料,其含有由下式(I)表示的化合物:其中R 1表示取代或未取代的具有1至5个碳原子的亚烷基; X表示水溶性基团; 并且R表示取代或未取代的总共14至40个碳原子的烷基,烯基,芳基,烷氧基,-NR 3 R 4(R 3和R 4各自独立地表示具有I至40的烷基 碳原子,氢原子或芳基),双环烷基,双环烯基,环烷基,环烯基或杂环基,条件是当X表示季铵盐结构时,R 2不表示烷基 具有14至17个碳原子的基团。
