ABSTRACT:
A silver halide photographic light-sensitive material is disclosed. The material is comprised of one or more light-sensitive silver emulsion layers and one or more light-insensitive layers. The silver halide layers or light-insensitive layers contain an ultraviolet ray absorbing polymer latex. The polymer latex is comprised of a homopolymer or copolymer having a repeating unit derived from monomers represented by the following general formula (I): ##STR1## wherein the substituents within a general formula (I) are defined within the specification. The polymer latex (I) contains a substituents Q which represents an ultraviolet ray absorbing group represented by the general formula (II): ##STR2## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 each represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, an alkylthio group having 1 to 20 carbon atoms, an arylthio group having 6 to 20 carbon atoms, an amino group, an alkylamino group having 1 to 20 carbon atoms, an arylamino group having 6 to 20 carbon atoms, a hydroxyl group, a cyano group, a nitro group, an acylamino group, a carbamoyl group, a sulfonyl group, a sulfamoyl group, a sulfonamide group, an acyloxy group or an oxycarbonyl group, and R.sub.1 and R.sub.2, R.sub.2 and R.sub.3, R.sub.3 and R.sub.4 or R.sub.4 and R.sub.5 may form a 5 to 6 member ring by ring closure; R.sub.6 represents a hydrogen atom or an alkyl group having 1 to 20 carbon atoms; R.sub.7 represents a cyano group, --COOR.sub.9, --CONHR.sub.9, --COR.sub.9 or --SO.sub.2 R.sub.9 ; and R.sub.8 represents a cyano group, --COOR.sub.10, --CONHR.sub.10, --COR.sub.10 or --SO.sub.2 R.sub.10 ; wherein R.sub.9 and R.sub.10 each represents an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 20 carbon atoms; wherein one of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 bonds to the vinyl group through the linking group. The photographic material which includes the polymer latex of the invention has excellent absorption characteristics in the 300 to 400 nm range and does not cause static marks caused by ultraviolet rays. Furthermore, the material does not undergo deterioration of color reproduction and fading or discoloration of color images caused by light.
