| titleOfInvention | Silver halide photographic materials |
| abstract | A silver halide photographic material, comprising: n at least one negative type silver halide emulsion layer coated onto a support; n at least one compound represented by general formula (I), said compound being included in at least said one emulsion layer; and n sensitivity specks present in at least one kind of silver halide grains which are included in the said emulsion layer whereby said sensitivity specks are present within the grains at a depth of at least 2 nm, but less than 50 nm, from the surface of the grains, with the number of said sensitivity speck on the surface of the grains being at least 1/10th, but not more than 5/10ths of the maximum value of sensitivity speck distribution in the depth direction, ##STR1## wherein, Z 2 represents a heterocyclic ring having at least one substituent group selected from the group consisting of --SO 3 M, --COOR 2 , --OH and --NHR 3 , M is selected from the group consisting of hydrogen atom, an alkali metal and an --NR 4 group, R 2 is selected from the group consisting of a hydrogen atom, an alkali metal and an alkyl group having from 1 to 6 carbon atoms, R 3 is selected from the group consisting of a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, --COR 4 , --COOR 4 and --SO 2 R 4 , and R 4 is selected from the group consisting of a hydrogen atom, an aliphatic group which may be substituted and an aromatic group which may be substituted. |
