PROBLEM TO BE SOLVED: To make it possible to form a cyan dye-forming picture superior in both of hue and color image fastness by incorporating at least one kind of specified cyan dye-forming coupler and at least each one of 2 kinds of specified compounds in an emulsion layer. SOLUTION: The emulsion layer contains at least one kind of cyan dye- forming coupler represented by formula I and at least each one of 2 kinds of compounds represented by formulae II and III, and in formulae I-III, each of R<1> and R<2> is electron attractive group having a Hammett's substituent constantσp of >=0.20; R<3> is a substituent; X is an H atom or the like; Y is a substituent; L is a single bond; R<a1> is an alkyl group; when L is a single bond, it expresses further a radical (.); R<a2> is an alkyl or the like; R<a3> is an alkenyl or the like; each of R<b1> and R<b2> is an aliphatic group or the like; R<b3> is a substituent; and each of (m) and (n) is an integer of 0-5. As a result, the obtained cyan dye is high in sensitivity to light in the wavelength region ranging from ultraviolet rays to visible light.
