PURPOSE:To form a print having a sufficient visual whiteness without deteriorating photographic performance, by specifying the mean reflectance at each wavelength of the unexposed area of photographic print after photographic processing. CONSTITUTION:A green sensitive silver halide emulsion layer containing a magenta coupler like 3-anilino-5-pyrazolones and a blue sensitive silver halide emulsion layer containing a blue sensitizing dye are provided on a support having a surface covered with polyolefin and containing anatase-type TiO2 and a blueing agent. The materials of the support and photographic constituent layers are properly selected so that mean reflectance measured by JIS-Z-8722 is above 70% on the surface of unexposed portion in the wavelength region of 570-660nm, remaining within + or -5% in the wavelength region of 480-570 nm, and within +10% in the wavelength region of 420-480 nm based on the value of 570-660nm. |
