发明名称 Silver halide photographic light-sensitive material
摘要 A silver halide photographic light-sensitive material is disclosed. The material comprises a substrate provided thereon with at least one silver halide emulsion layer comprising at least one compound represented by the following Formula (I): <IMAGE> wherein Ra and Rb each represents a hydrogen atom, an alkyl group having at least two carbon atoms or an aryl or heterocyclic group, provided that Ra and Rb do not simultaneously represent hydrogen atoms; La and Lb each represents a methylene group; L1 and L2 each represents a methine group; p1 represents 0 or 1; Z1 represents an atomic group required for forming a 5- or 6-membered nitrogen atom-containing heterocyclic ring; M1 represents a counterion required for balancing the electrical charge; m1 represents a numerical value of not less than 0 required for neutralizing the molecule; and Q represents a methine or polymethine group required for forming a methine dye. The light-sensitive material provides substantially low fogging, has high sensitivity and excellent storage stability and can provide images of high quality.
