Abstract

Abstract A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support having thereon a light-sensitive silver halide layer and a light-insensitive layer. The material may also contain other layers and one or more layers contains an ultraviolet ray absorbing polymer latex. The polymer latex is comprised of a homopolymer or a copolymer having a repeating unit derived from a monomer represented by the following general formula (I): ##STR1## within the general formula (I) the Q represents an ultraviolet ray absorbing group represented by the general formula (II): ##STR2## the substituents within the general formulae (I) and (II) are defined in a specification. The photographic light-sensitive material has excellent absorbing characteristic in the 300 to 400 nm range and does not cause static marks caused by ultraviolet layer. Furthermore, the material does not undergo discoloration. In addition, the photographic material has good film strength and a reduced layer thickness and provides a color image having an improved sharpness and which is free from fading and discoloration caused by light.
