Photographic properties were measured for each of the obtained samples. The results are shown in Table 1. In the table, relative sensitivity values are expressed with the maximum sensitivity value when processed with color developer [ ] as 100.

[Table] As is clear from the above Table 1, the samples obtained using the coupler according to the present invention are excellent in that good sensitivity and maximum density can be obtained regardless of the presence or absence of benzyl alcohol. Furthermore, as a result of measuring the color spectrum, it was found that the dye using the coupler of the present invention has the maximum absorption in a relatively long part of the red region, and exhibits excellent color purity with little absorption on the short wavelength side. . Example 2 A sample obtained in the same manner as in Example 1 was used to examine the light resistance, heat resistance, and moisture resistance of the dye image. The results obtained are shown in Table 2.

[Bleach-fix solution composition]

Ethylenediaminetetraacetate iron ammonium salt
50g ammonium sulfite (40% solution) 50ml ammonium thiosulfate (70% solution) 140ml aqueous ammonia (28% solution) 20ml ethylenediaminetetraacetic acid 4g hydrosulfite 5g Add water to make 1. The maximum reflection density of the cyan dye of the sample obtained after the development process was measured. The results are shown in Table 4. Incidentally, the dye residual rate at the maximum density portion was determined as follows. Dye residual rate = Fatigue bleach-fix solution treatment/new bleach-fix solution treatment x 100

[Table] From Table 4, it can be seen that the samples using the coupler according to the present invention show less fading of the cyan dye when treated with a fatigue bleach-fix solution. Example 5 Couplers of the present invention as shown in Table 5, the comparative coupler [D], and the following comparative couplers [E] and [F] were prepared, exposed, and developed in the same manner as in Example 3. A sample was obtained. (Sample Nos. [19] to [25]) Using these samples, the light resistance, heat resistance, and moisture resistance of cyan dye images were tested under the same conditions as in Example 2. The results obtained are shown in Table 5.

Table 5 shows that the samples using the cyan coupler according to the present invention have excellent performance in terms of light resistance, heat resistance, and moisture resistance. Example 6 A sample was obtained in the same manner as in Example 5 except that the coupler of the present invention was changed to a compound shown in Table 6. Using this sample, the light resistance, heat resistance, and moisture resistance of the cyan dye image were tested under the same conditions as in Example 2. The results obtained are shown in Table 6.
