Definitions
- the present invention relates to a method of processing color photographic light sensitive elements and particularly to a bleaching process for color photographic light sensitive elements by processing them in a bleaching solution containing at least one member selected from the group consisting of an aliphatic primary amine, an aliphatic secondary amine, an aliphatic tertiary amine, and a salt thereof, said amine being represented by the general formula wherein R R and R represent a member selected from the group consisting of a hydrogen atom, an unsubstituted alkyl group, a substituted alkyl group, an unsubstituted aliphatic group, a substituted aliphatic group, and a heterocyclic ring with another group, the total number of carbon atoms in R R and R being less than 12.
- processings for color photographic light sensitive elements are carried out by color development, stop-fixing, bleaching (silver removal) and fixing followed by washing, hardening stabilization and the like.
- Various processing compositions dependent upon the types of color photographic light sensitive elements are required in these processings.
- a typical example of a bleaching process for color photographic light sensitive elements is the method where by a bleaching composition containing a ferricyanide is used or a method whereby a bleaching composition containing a water-soluble iron complex salt such as Feethylenediaminetetraacetic acid complex is used.
- a bleaching composition containing a ferricyanide is used or a method whereby a bleaching composition containing a water-soluble iron complex salt such as Feethylenediaminetetraacetic acid complex is used.
- a thiosulfate which is usually used as a fixing agent is present in the bleaching composition, the thiosulfate, will be decomposed as the oxidizing power of the ferricyanide is high.
- the bleaching bath must be maintained separate from the fixing bath. Hence it requires a long period of time to accomplish the processings. Furthermore, the ferricyanide is unstable in the bleaching composition and will tend to be converted into a ferrocyanide.
- a thiosulfate may be present in the system and bleaching and fixing may be carried out in a same bath.
- the bleaching power of the bleach-fixing (blixing) bath is not always suificiently high.
- various bleaching promoting agents have been investigated for improving the bleaching power in the bleaching system (e.g., German Patented May 11, 1971 Patent No. 1,127,715), there are several attendant disadvantages (i.e., color stain or color fog tends to form).
- an object of the present invention is to provide a color photographinc bleaching process having a sutficient bleaching power with no accompanying color stains.
- Another object of this invention is to provide a bleaching method for color photographic light sensitive elements using a bleach-fixing composition containing a water-soluble iron complex salt which yields no color stains.
- Still another object of this invention is to provide a method of processing color photographic light sensitive elements and for providing good color images by directly subjecting the color photographic light sensitive elements to a bleach-fixing processing after color development without applying a stop-fixing processing.
- aforesaid objects of this invention can be accomplished by adding to a bleach-fixing composition an aliphatic primary amine, aliphatic secondary amine, or aliphatic tertiary amine represented by the general formula R1 N Rz wherein R R and R each represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted alicyclic group, or may form a heterocyclic ring together with any other group, the total sum of the carbon numbers of R R and R being less than 12, or a salt thereof.
- the bleaching (silver-removing) power of the bleach-fixing bath can be markedly increased.
- the alkyl group or the alicyclic group it may be substituted with a halogen, an amino group, etc.
- the formation of color stains may be very effectively prevented by incorporating the aforesaid compound in a bath between the color developing bath and the stop-fixing bath, in a stop-fixing bath, or in a bath between the stop-fixing bath and the bleach-fixing bath.
- the compounds represented by the above formula may be known as additives in the preparation of photographic emulsions for purposes other than those of the present invention, such as reduction sensitizers.
- the compound is added to the aforesaid processing composition in the amount used in these known techniques or if the compound is added to the photographic emulsions during the preparation thereof, neither the bleach promoting effect nor the color stain preventing elfect of the present invention can be obtained.
- the amounts of the aforesaid compound employed may range from about 03-50 g./l., particularly 2-10 g./liter of the processing bath. Since the compounds of this invention are alkaline, the pH of the bleach-fixing solution containing the compound must be adjusted to 6.4-7.1. In addition, the compounds shown above may be used alone or as mixtures thereof.
- Example 1 Each of Compounds 1-9 mentioned above was added to a bleach-fixing bath having the following composition in an amount of g. per liter of the bath.
- EXAMPLE 2 An aqueous solution containing 2 g./liter of each of Compounds 1-9 was prepared. After exposing, color developing and stop-fixing, a color photographic printing paper was immersed for 2 minutes in the aqueous solutions thus prepared and thereafter processed in a conventional bleach-fixing solution having the control composition of Example 1. The results were compared with the case where the same color photographic printing paper was processed in the bleach-fixing bath without being immersed in the aqueous solution containing the compound of this invention. The results are shown in the following 1 Time required for finishing the bleach-fixing processing.
- Example 3 and Additive C-1 (3- 0-3 0- -6 -7 (3-8 G- 9 Control Yellow stain 0. 18 0. 18 0. 18 0- 18 0. 18 0. 18 0- 18 0. 18 O, 18 0, 45 Magenta stain 0. 15 0. 15 0. 15 0. 15 0- 15 0 15 0. 15 0. l5 0. 16 0, Cyan stain 0. 12 O. 12 0. 12 0. 12 0- 12 0. 12 0. 12 0. 12 0, 12 0,
- a method of color processing color photographic light sensitive elements comprising, at least, the steps of color development, stop-fixing, and bleach-fixing, the improvement which comprises processing the light sensitive element in a bath selected from the group consisting of a bleach-fixing bath and a bath located between color developing and bleach-fixing, said bath containing at least one member selected from the group consisting of water-soluble amines and salts thereof represented by the general formula:
- R R and R represent a member selected from the group consisting of a hydrogen atom, but no more than two of R R or R can be a hydrogen atom at any one time, an unsubstituted alkyl group, a substituted alkyl group wherein said substituent is selected from the group consisting of a halogen group and an amino group, an unsubstituted alicyclic group, a substituted alicyclic group, and a heterocyclic ring with another group, the total number of carbon atoms in R R and R being less than 12.
- a method of color processing a photographic light sensitive color element comprising image-wise exposing the element, developing the exposed element by a developer capable of forming a silver and a color image and bleach-fixing the developed element to remove the silver image, the improvement which comprises processing the color element in a bleach-fixing bath containing a watersoluble iron complex salt and a water soluble amine compound selected from the group consisting of 5.
- said water-soluble iron complex salt is the iron complex salt of ethylene diamine tetra-acetic acid.
