摘要： PURPOSE:To prevent halation, light leakage emulsion fog of a photographic film without adverse effect to photographic characteristics of the film by coloring the photographic polyester film with special dye having 420-460nm of maximum absorption wavelength. CONSTITUTION:A polyester film is dyed with a yellow dye represented by the formula together with a dye having 530-570nm of maximum absorption wavelength and a dye having 640-680nm of maximum absorption wavelength. This yellow dye incorporates superior anti-sublimation and heat resistance to the conventional dye and exhibits higher optical density with less amount than the conventional dye. Accordingly, even if its sensitivity decrease is limited to lower limit, it can provide sufficient anti-halation and light leakage preventive effect. In the formulae, R1 represents H, NH2, NHR2, NR2R3, Cl, Br, or 4-1C alkyl group or the like, X represents Cl, Br of 4-1C alkyl group, Y represents H, Cl or Br, R2 and R3 represent 4-1C alkyl group, phenyl group, n represents 0 to 2, m represents 1 to 4, when Y=H and n=0, R1 represents NHR2, NR2R3, and when m=higher than 2, R1 may be or not be the same as R2 or R3.
