发明名称 SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL
摘要 PURPOSE:To obtain a colored photographic material having an improved fastness against light of a Magenta colored image and an excellent color reproducibility by incorporating at least one of specific couplers contg. a nitrogen atom and at least one of specific stabilizers for a colored image contg. an oxygen atom. CONSTITUTION:The titled material contains at least one of couplers shown by formula I and at least one of the compds. shown by formula (XI). In the Magenta coupler (I), R is a hydrogen atom or a substituent, said substituent of R is a halogen atom or a heterocyclic thio group. Said halogen atom comprises a chlorine or a bromine atom, preferably a chlorine atom. The stabilizer of the Magenta colored image joint-used with a Magenta coupler has an anti-decoloring effect of the Magenta colored image against light and also an anti-discoloring effect of the Magenta colored image against light and is a chroman or a chraman compds. shown by formula XI. The compounding amount of the stabilizer of the Magenta colored image is 5-300mol%, preferably 10-200mol% on the basis of the one of the Magenta coupler.
