Abstract
In a silver halide photographic light-sensitive material having at least one silver halide emulsion layer on a support, at least one of the silver halide emulsion layers contains a light-sensitive silver halide emulsion, in which tabular grains having an aspect ratio of 2 or more occupy 50% or more of a total projected area of silver halide grains, and a polymer represented by Formula (1) below in an amount of 10.sup.-3 to 10 g per mole of the silver halide. In Formula (1), A represents a repeating unit derived from an ethylenic unsaturated monomer having at least one basic nitrogen atom, and B represents a repeating unit, other than A, derived from an ethylenic unsaturated monomer. x and y each represents a percentage by weight. x represents 0.1 to 100, and y represents 0 to 99.9. ##STR1##
