PURPOSE:To obtain the title material which is improved in the color balance between a magenta color picture and a yellow color picture at the time of processing the material in a light room and has the excellent light resistance by incorporating a specified 5-pyrazolone magenta coupler, a specified yellow coupler and a specified noncoloring compd. in a green sensitive emulsion layer. CONSTITUTION:The 5-pyrazolone magenta coupler having a group shown by formula I at the coupling position of a pyrazolone nucleus is incorporating in at least one layer of the green sensitive emulsion layers, and the yellow coupler shown by formula II and the noncoloring compd. shown by formula III are incorporated in at least one layer of the blue sensitive emulsion layers. In formulas I, II and III, L1 and L2 are each methylene or ethylene group, R1 is hydrogen atom, alkyl or aryl group, etc., R3 is halogen atom or alkoxy group, R6 is alkyl or alkoxy group. Thus, the photosensitive material which has the improved shelf-life of the picture and does not break the color balance, even at the time of exposing the material with a light for a long period, is obtd. |
