PURPOSE:To eliminate the unfavorable influence of ultraviolet rays and to prevent the formation of static marks, etc. and irregularity in color reproducibility by combinedly adding specified 1 kind of ultraviolet absorber and >=1 kind of ultraviolet absorber selected from other specified 3 kinds of ultraviolet absorbers. CONSTITUTION:To an emulsion layer, especially a surface protective layer, a backing layer or an antihalation layer are combinedly added >=1 kind of ultraviolet absorber represented by formulaI(where each of R1-R5 is H, halogen, 1-6C alkyl, alkoxy, aryl, alkylsulfone or the like) and >=1 kind of ultraviolet absorber selected from 3 kinds of ultraviolet absorbers represented by formulae II-IV (where each of R6 and R7 is H, alkyl or aryl, each of A and B is CN, SO2R18, COOR19 or the like, each of R18 and R19 is alkyl or aryl, each of R9- R12 is H or alkyl, each of R8 and R13 is alkyl or aryl, each of R14 and R15 is H, alkyl or aryl, G is an electron attractive group such as CN, (n) is 1 or 2, when (n) is 1, each of R16 and R17 is alkyl, aryl or cyclic alkyl, and when n is 2, each of R16 and R17 is alkylene or arylene). Thus, the influence of heat is also eliminated after coating an emulsion and drying it, and a photosensitive material with superior sensitivity, etc. is obtd. |
