Definitions
- This invention relates to a method for processing lightsensitive silver halide color photographic materials, particularly to a process for quick bleaching of developed silver image.
- the bleaching bath containing potassium ferricyanide is sufficient in bleaching power, but is undesirably strong in oxidizing power. Accordingly, thiosulfate which is a solvent for silver halide cannot be incorporated into the bath, and thus a fixing bath should necessarily be used separately to bring about a disadvantage particularly in the case of quick processing.
- the bleaching bath containing a water-soluble ferric salt of EDTA thiosulfate can be incorporated into the bath, and thus the bleaching and fixing of photographic material can be effected in one bath.
- the said bath has such drawback that is is weak in bleaching power and requires a long processing time, and the actual state is such that in case developed silver formed by use of such a black-and-white developer as used in the case of reversal color development, an ordinary EDTA ferric salt bleaching bath cannot be put into practical use because of its being insutficient in bleaching power.
- a compound of the general formula Br Br wherein R and R are individually a hydrogen atom, a lower alkyl group, an allyl group (C H or an amino group; and nis 0 or a positive integer of l to 5, displays a markedly excellent bleach-promoting eflect when incorporated into an EDTA ferric salt bleach-fixing solution.
- the compound of the Formula I forms no such color fog as in the case of thiourea, even when incorporated into a color developer and has a bleach-promoting action equivalent to or more than that of thiourea, even when used in a slight amount, thereby to make it possible to shorten the bleaching time to V; or more.
- a bath used prior to the bleach-fixing such as a stopping, stop-fixing or intermediate bath, the bleach-fixing is complete within an extremely short period of time.
- EXAMPLE 1 A color photographic paper was exposed, subjected to color development (20 C., 10 min.), stop-fixing (20 C., 3 min.) and water-washing (l822 C., 5 min.) and then treated with the following EDTA ferric salt bleachfixing solution (20 C.):
- Color developer G. Sodium sulfite 3 N-ethyl-N-hydroxyethyl-p-phenylenediamine 5 Potassium bromide 1.5 Hydroxylamine sulfate 2.5 Sodium carbonate (monohydrate) 50 Water to make 1.0 liter.
- Bleach-fixing solution G. EDTA ferric salt 50 Sodium carbonate (monohydrate) 3 Ammonium thiosulfate 240 Anhydrous sodium sulfite 10 Wate 2 m ke l-Q liten
- G. EDTA ferric salt 50 Sodium carbonate (monohydrate) 3
- Ammonium thiosulfate 240 Anhydrous sodium sulfite 10 Wate 2 m ke l-Q liten
- Example 2 was repeated, except that the second stopping was effected in the same bath as in the first stopping, and the film was washed with water and then treated at 20 C. for 2 minutes with a 0.1% aqueous solution of each of the Compounds 1 to 9, followed by bleach-fixing. In every case, the bleaching was complete within 5 minutes.
- EXAMPLE 4 A color photographic paper using a polyethylene laminate paper as the support was exposed and then subjected to the following processings:
- the photographic paper was insufiiciently bleached and was turbid in color, whereas in case the Compound 3 had been incorporated into the developer, the photographic paper was completely bleached and a color print could be obtained in such a short time as 5 minutes.
- a method for bleach-fixing an exposed, develop light-sensitive silver halide photographic material with a water-soluble ferric salt of ethylenediamine tetraacetic acid and a fixing agent comprising the bleach-fixing being carried out in the presence of a dithiourea compound by processing the photographic material with a bleach-fixing solution or with a bath used prior to the bleach-fixing, the solution or the bath containing therein the dithiourea compound in an amount of from 0.02 g. to 5 g. per liter of bath or solution, the dithiourea compound being represented by the general formula:
- n is 0 or a positive integer of 1 to 5.
- a solution for bleach-fixing an exposed, developed light-sensitive silver halide photographic material comprising water, a water-soluble ferric salt of ethylenediamine tetraacetic acid, a fixing agent and a dithiourea compound, the dithiourea Compound having been incors 5 6 porated in an amount of from 0.02 g. to 5 g.
