<p>A method for photographically recording an information pattern on a photographic film is disclosed. The method comprises the steps of (1) writing an information pattern at an area outside the picture taking area of a silver halide color photographic film with a red-light having an intensity peak at a wavelength of 620 nm or more emitted from a photo-emission diode, (2) processing the color photographic film, and (3) optically reading an image of the pattern formed on the color photographic film with red-light having a intensity peak a wavelength of 620 nm or above. In the method, a red-sensitive silver halide emulsion layer of the color photographic film contains a coupler represented by the following Formula CU; <CHEM> wherein X is a substituent capable of splitting-off upon reaction with the oxidation product of an aromatic primary amine color developing agent; R<1> is an aryl group or a heterocyclic group; R<2> is a an aliphatic group or an aryl group; and the above groups represented by R<1> or R<2> each may have a substituent.</p> |
