Silver halide photographic emulsion

A method for preparing a silver halide emulsion comprising the steps of:

• (1) forming a silver halide grain emulsion,
• (2) subjecting the formed silver halide emulsion to desalting to remove soluble salts,
• (3) subjecting the silver halide emulsion to spectral and/or chemical sensitization, and
• (4) preparing a coating solution using the spectrally and/or chemically sensitized silver halide emulsion, wherein in any of the steps (1) to (4), a compound represented by the following formula (I) is incorporated into the silver halide emulsion:
• {X—(L1)n1}n2—L2—(SOL)m formula (I)
• wherein
• X represents a chlorine atom or a bromine atom;
• L1 is represented by formula (II):
• —C(R1)(R2)—CH(R3)—EWG— formula (II)
• wherein R1, R2 and R3 each represent a hydrogen atom or a substituent;
• and EWG represents —COO—, —OCO—, —SO2—, —CON(R4)—, —N(R4)CO—, —CSN(R4)—, —N(R4)CS—, —N(R4)—, —O—, —S—, —CO—, —CS—, —COCO—, —SO2N(R4)— or —N(R4)SO2—, in which R4 represents a hydrogen atom, an alkyl group or an aryl group;
• L2 represents a bivalent linkage group, which is an aromatic group;
• SOL represents a water-solubilizing group;
• n1 is 1;
• and
• m and n2 each are an integer of 1 to 4.
