    • A novel silver halide photographic material comprising at least one methine compound represented by the following general formula (I): ##STR1## wherein R.sup.1 represents --(CH.sub.2).sub.r --CONHSO.sub.2 --R.sup.3, --(CH.sub.2).sub.s --SO.sub.2 NHCO--R.sup.4, --(CH.sub.2).sub.t --CONHCO--R.sup.5 or --(CH.sub.2).sub.u --SO.sub.2 NHSO.sub.2 --R.sup.6 in which R.sup.3, R.sup.4, R.sup.5 and R.sup.6 each represents an alkyl group, alkoxy group or amino group, r, s, t and u each represents an integer 1 to 5; and R.sup.2 represents has the same meaning as R.sup.1 or represents an alkyl group; Z.sup.1 and Z.sup.2 each represents a nonmetallic atom group required to form a 5- or 6-membered heterocyclic group; p and q each represents an integer 0 or 1; L.sub.1, L.sub.2 and L.sub.3 each represents a methine group; m represents an integer 0 to 2; X represents an anion; and k represents an integer required to adjust the charge in the molecule to 0. The silver halide photographic material may comprise at least one methine compound represented by the general formula (I) and at least one water-soluble dye.
    • 一种新型的卤化银照相材料,其包含由以下通式(I)表示的至少一种次甲基化合物:其中R1表示 - (CH2)r-CONHSO2-R3, - (CH2)s-SO2NHCO-R4 , - (CH2)t-CONHCO-R5或 - (CH2)u-SO2NHSO2-R6,其中R3,R4,R5和R6各自表示烷基,烷氧基或氨基,r,s,t和u各自表示 整数1〜5; 和R 2表示与R 1相同或表示烷基; Z1和Z2各自表示形成5或6元杂环基团所需的非金属原子团; p和q各自表示整数0或1; L1,L2和L3各自表示次甲基; m表示0〜2的整数。 X表示阴离子; 并且k表示将分子中的电荷调节至0所需的整数。卤化银照相材料可以包含至少一种由通式(I)表示的次甲基化合物和至少一种水溶性染料。
