Abstract
A silver halide photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion and at least one light-insensitive layer is disclosed. One or more of the layers of the material contains an ultraviolet ray absorbing polymer latex which comprises a homopolymer or copolymer having a repeating unit derived from a monomer represented by the general formula (II) in which one or more ultraviolet ray absorbing compounds represented by the general formula (I) is loaded: ##STR1## the substituents within the general formula are defined within the specification. The material has excellent absorption characteristics in the 300 to 400 nm range and does not cause static marks caused by ultraviolet rays or undergo deterioration of color reproduction. In addition, the material has good film strength and reduced layer thickness and provides a color image having improved sharpness which is free from fading or discoloration due to light.
