    摘要： Disclosed herein is a silver halide photographic light-sensitive material having at least one silver halide emulsion layer formed on a support. Said light-sensitive material having at least one layer contains a regular silver halide emulsion, a tabular silver halide emulsion containing tabular silver halide grains having an average diameter/average thickness ratio of 2 or more, which occupy 50% or more of the total projected area of all silver halide grains, and a silver halide emulsion containing internal latent-image silver halide grains each chemically sensitized to the depth of less than 0.02 .mu.m from the surface of the grain. Each of these emulsions contains at least one methine compound represented by the following formula (I): ##STR1## where R.sup.1 is --(CH.sub.2).sub.r --CONHSO.sub.2 --R.sub.3 or --(CH.sub.2).sub.s --SO.sub.2 NHCO--R.sub.4, where R.sup.3 and R.sup.4 are an alkyl group, r and s are an integer ranging from 1 to 5; R.sup.2 is a sulfoalkyl group; Z.sup.1 and Z.sup.2 are non-metal atom groups required for forming a 5- or 6-membered heterocyclic group; p and q are 0 or 1; L.sub.1, L.sub.2 and L.sub.3 are methine groups; and m is 0, 1 or 2, wherein said at least one methine compound has been added at 50.degree. C. or more in any step from a step of preparing of the emultion to a step of coating of the emulsion.
