A silver halide photographic light-sensitive material comprising a support and at least one silver halide emulsion layer formed on the support, said emulsion layer containing at least one silver halide emulsion which is a tellurium-sensitized monodispersed emulsion, wherein said silver halide emulsion has been tellurium-sensitized in the presence of at least one compound represented by the following formula (I):
- ##STR56## where R.sub.1, R.sub.2 and R.sub.3 are aliphatic groups, aromatic groups, heterocyclic groups, OR.sub.4, NR.sub.5 (R.sub.6), SR.sub.7, OSiR.sub.8 (R.sub.9)(R.sub.10), X or hydrogen atoms, R.sub.4 and R.sub.7 are aliphatic groups, aromatic groups, heterocyclic group, hydrogen atoms or cations, R.sub.5 and R.sub.6 are aliphatic groups, aromatic groups, heterocyclic groups or hydrogen atoms, R.sub.8, R.sub.9 and R.sub.10 are aliphatic groups, and X is a halogen atom.
A silver halide photographic light-sensitive material comprising a support and at least one silver halide emulsion layer formed on the support, said emulsion layer containing at least one silver halide emulsion which is a tellurium-sensitized monodispersed emulsion, wherein said silver halide emulsion has been chemically tellurium-sensitized in the presence of at least one tellurium sensitizer of such type that silver telluride is formed at a pseudo-first-order reaction rate constant k of 1.times.10.sup.-8 to 1 min.sup.-1, wherein said monodispersed silver halide emulsion has a variation coefficient of 22% or less in terms of grain-size distribution, and said silver halide emulsion has been tellurium-sensitized in the presence of at least one compound represented by the following formula (I):
- ##STR57## where R.sub.1, R.sub.2 and R.sub.3 are aliphatic groups, aromatic groups, heterocyclic groups, OR.sub.4, NR.sub.5 (R.sub.6), SR.sub.7, OSiR.sub.8 (R.sub.9)(R.sub.10), X or hydrogen atoms, R.sub.4 and R.sub.7 are aliphatic groups, aromatic groups, heterocyclic group, hydrogen atoms or cations, R.sub.5 and R.sub.6 are aliphatic groups, aromatic groups, heterocyclic groups or hydrogen atoms, R.sub.8, R.sub.9 and R.sub.10 are aliphatic groups, and X is a halogen atom.
A silver halide photographic light-sensitive material comprising a support and at least one silver halide emulsion layer formed on the support, said emulsion layer containing at least one silver halide emulsion which is a tellurium-sensitized monodispersed emulsion, wherein said silver halide emulsion has been chemically tellurium-sensitized in the presence of at least one compound represented by the following formula (IIA):
- ##STR58## wherein R.sub.13 and R.sub.15 combine with each other to form an alkylene group, an arylene group, an aralkylene group or an alkenylene group;
- and each of R.sub.14 and R.sub.16 represents an alkyl group or an aromatic group.
A silver halide photographic light-sensitive material comprising a support and at least one silver halide emulsion layer formed on the support, said emulsion layer containing at least one silver halide emulsion which is a tellurium-sensitized monodispersed emulsion, wherein said silver halide emulsion has been chemically tellurium-sensitized in the presence of at least one compound represented by the following formula (IIB):
- ##STR60## wherein R.sub.11 and R.sub.15 combine with each other to form an alkylene group, an arylene group, an aralkylene group or an alkenylene group;
- and R.sub.16 represents an alkyl group or an aromatic group.
