PURPOSE:To obtain color photographs of high image durability by exposing images to a color photographic material wherein silver halide (emulsion) and specific dyes are contained in the fine pores of an anodized aluminum film and developing this then bleaching the material by a silver dye bleaching method. CONSTITUTION:A processed negative film is printed to a color photosensitive material wherein a silver halide emulsion 15 and dyes R(red), G(green) and B(blue) are respectively contained in the fine pores of an anodized Al2O3 film 14 by white light W, after which it is subjected to black and white developing. In the fine pores contg. the dye B in the parts corresponding to the Y color image phase of the negative, the silver halide is not sensitized, and in the fine pores contg. the dyes R and G, the silver halide is sensitized and developed, whereby the reduced silver images are formed in the image shape of positive with respect to the negative Y color image. In the parts corresponding to the C color image phase, the parts contg. the dyes B and G are developed. If the photosensitive plate is processed in a dye bleaching bath, only the dye B in the parts corresponding to the Y color image phase part of the negative and the R color image in the parts corresponding to the C color image phase are left. If this is desilvered in a bleach-fix bath and is boiled in water, the openings of the fine pores are sealed by Al(OH)3 and the color print reproducing the color image of the original subject faithfully is obtained. |
