PURPOSE:To obtain the titled material having an excellent photographic property by incorporating an anti-diffusive photographic useful compd. having prescribed group and sulfo group to the titled material. CONSTITUTION:The titled material contains the anti-diffusive photographic useful compd. having sulfo group and the group shown by the formula I wherein R1 and R2 are each >=2C an aliphatic group, (r) is 0 or 1. Said photographic useful compd. comprises an image forming coupler, a color correction coupler, a a development restrainer releasing coupler, a color mixture preventing agent, a competitive compd. a fog preventing agent, a fade preventing agent, an ultraviolet absorption agent, and a dye or a stain preventing agent. The prescribed compd. is used by incorporating it to an emulsion or a gelatin layer. When the anti-diffusion property of the prescribed compd. is given by the groups shown by R1 and R2, the total of the carbon number contd. in the groups of R1 and R2 is preferably 10-30. |
