  • ferric chloride as ferric ion in an amount of 5 ppm and calcium nitrate as calcium ion in an amount of 150 ppm to prepare Specimens 101 to 113.
  • These specimens were each packed into a hard vinyl chloride container having a length of 10 cm, a width of 25 cm and a depth of 30 cm in an amount of 5 l.
  • the solution in the container was continuously circulated at a rate of 3 l per minute by means of a pump while being kept to a temperature of 38°C for 30 days for ageing test.
  • the liquid surface was covered by a floating cover by 200 cm2 and left open to the air by 50 cm2.
  • a multi-layer color photographic material specimen 101 described in Example 1 of JP-A-4-274236 was cut into strips having a width of 35 mm, and then wedgewise exposed to light with 5CMS at a color temperature of 4,800°K.
  • the photographic sensitive material specimen was then processed with the color developer specimens 101 to 113 which had been just prepared (fresh solution) or the same color developer specimens which had been aged in accordance with the following procedures: Processing step Processing time Processing temperature (°C) Color development 3 min. 15 sec. 37.8 Bleach 50 sec. 38.0 Fixing 1 min. 40 sec. 38.0 Rinse (1) 30 sec. 38.0 Rinse (2) 20 sec. 38.0 Stabilization 20 sec. 38.0
  • Tap water was passed through a mixed bed column filled with an H type strongly acidic cation exchange resin (Amberlite IR-120B produced by Rohm & Haas) and an OH type anion exchange resin (Amberlite IR-400) so that the calcium and magnesium ion concentrations were each reduced to 3 mg/l or less.
  • H type strongly acidic cation exchange resin Amberlite IR-120B produced by Rohm & Haas
  • Amberlite IR-400 OH type anion exchange resin
  • the specimen which had been processed with the fresh solution exhibits B density of 2.5 when measured with blue light
  • the specimen which had been processed with the aged solution was measured for B density by means of a Type X Light 310 photographic densitometer to determine a difference ⁇ D B from that of the fresh solution. Further, the percent residue of developing agent and hydroxylamine after ageing were determined by analysis. Moreover, the color developers which had been aged were visually examined for the presence of precipitate. The results are set forth in Table 1.
  • Table 1 shows that the use of conventional chelating agents leaves much to be desired in the prevention of precipitate and the maintenance of solution stability while the use of the compound of the present invention provides great effects.
  • Example 1 To the fixing solution of Example 1 were added the present compounds 1, 2, 3, 4, 7, 13, 21, 22, 30 and 31, respectively, in an amount of 3 g/l, and ferric ions corresponding to those brought over from the prebath bleaching solution to prepare Specimens 201 to 210. These specimens were aged at a temperature of 38°C with an opening value of 0.1 cm ⁇ 1 for 30 days, and then observed for turbidity. The specimens free of compound of the present invention showed a remarkable turbidity after ageing while the specimens comprising the compound of the present invention incorporated therein all stayed transparent, showing no precipitation.
  • the stabilizing solution of Example 1 was used as Comparative Specimen 301.
  • the multi-layer color photographic light-sensitive material specimen 101 was then processed with the fresh form of the color developer as used for Specimen 101 in Example 1.
  • the multi-layer color photographic light-sensitive material specimen 101 which had been thus processed was then aged at a temperature of 45°C and a relative humidity of 70% for 1 week.
  • the magenta stain increase ( ⁇ Dmin) from before ageing to after ageing was then determined.
  • Table 2 shows that the use of the stabilizing solution of the present invention containing the compound of the present invention inhibits the stain increase and improves the image preservability.
  • the foregoing color developer was used Specimen 401. To the same color developer were added the compounds of the present invention and comparative compounds in amounts set forth in Table 3, respectively, to prepare Specimens 402 to 408. To these color developers were then added ferric ion in an amount of 5 ppm and calcium ion in an amount of 150 ppm, respectively. These color developers were then aged in a beaker with an opening value of 0.10 cm ⁇ 1 at a temperature of 38°C for 20 days.
  • Specimen 103 described in JP-A-4-145433 was subjected to gradation exposure through a three-color separation filter for sensitometry. The exposure was effected in such a manner that an exposure of 250CMS reached for 0.1 second.
  • the photographic light-sensitive material thus exposed was then processed with the foregoing color developer which had been just prepared (fresh solution) and the same color developer which had been aged (aged solution) in accordance with the following procedures: Processing step Temperature (°C) Time (sec.) Color development 38 45 Blix 35 25 Rinse 1 35 20 Rinse 2 35 20 Rinse 3 35 20 Drying 80 60
  • Ion-exchanged water (calcium and magnesium concentrations: 3 ppm or less each)
  • Dmin minimum yellow density
  • magenta sensitivity log E of exposure which gives a density of 0.5
  • Table 3 shows that the use of the compound of the present invention provides small ⁇ Dmin and ⁇ S values, showing reduced flutuations of photographic properties. Further, the use of the compound of the present invention provides a great improvement in the inhibition of precipitation as compared to the comparative compounds. In particular, the comparative compounds which exert a great effect of inhibiting precipitation exhibit a poor preservability of developing agent while the comparative compounds which cause little decomposition of developing agent leave much to be desired in the inhibition of precipitation. On the contrary, the compound of the present invention provides a stable developer free from precipitation.
  • a color developer (A) was prepared having the composition as mentioned below. Further, a color developer (B) was prepared by replacing disodium ethylenediaminetetraacetate in the color developer (A) by Exemplary Compound 3 in the equimolecular amount. The two color developers were aged at a temperature of 40°C for 4 days. Specimen B-6 of an example in JP-A-3-174148 was then subjected to running processing with the color developers, respectively. As a result, the color developer (B) showed some improvement in the inhibition of precipitation. The percent residue of hydroquinone and potassium sulfite in the developer and the pH value of the developer after ageing were determined. As a result, it was found that the use of the compound of the present invention provides minimum loss of hydroquinone and potassium sulfite by air oxidation and hence a reduced rise of pH.
  • the compounds of the present invention and a comparative compound were subjected to a biodegradability test in accordance with an amended SCAS method defined in PECD chemical test guide line. The results are set forth in Table 4.
  • Table 4 shows that the compound of the present invention exhibits an excellent biodegradability.
