Definitions
- Color processing in general, consists of a number ofsteps, such as, color developing, stopping, bleaching, fixing, hardening and stabilizing, which need various chemicals depending on the light-sensitive materials to be processed.
- steps such as, color developing, stopping, bleaching, fixing, hardening and stabilizing, which need various chemicals depending on the light-sensitive materials to be processed.
- Such processings are carried out, for example, by passing the material to be processed through a color developing bath, a stop fixing bath, a water washing bath, a bleach-fixing bath, another water washing bath, a hardening bath, a further water washing bath and a stabilizing bath.
- the material maybe passed through the successive baths by leader belt and and roller means.
- potassium ferricyanide tends to be convened into potassium ferrocyanide.
- the bleaching and fixing power is not always sufficient, but the coexistence of the oxidizing agent and thiosulfate is possible. Therefore the bleaching and fixing can proceed simultaneously in one bath.
- thiourea or its derivative may be added to the bleach-fixing bath so as to increase the bleaching utility.
- color stain often occurs from contamination of bleachfixing solution with the color developing solution. This phenomenon has been proved to relate closely to the construction of photographic materials and the type of photographic emulsions.
- the upper layer is more susceptible to color stain. Therefore, in a color printing paper consisting of a red-sensitive layer with a cyan coupler as the uppermost layer, a green-sensitive layer with a magenta coupler as the middle layer, and a blue-sensitive layer with a yellow coupler as the lowermost layer, for example, cyan color stain occurs. Conversely, in a color printing paper having a blue-sensitive layer containing a yellow coupler as the uppermost layer, a green-sensitive layer containing a magenta coupler as the middle layer, and a red-sensitive layer containinga cyan coupler as the lowermost layer, yellow color stain occurs.
- a magenta color stain occurs in a color positive film having three emulsion layers in thefollowing order, from the top, a green-sensitive layer containing a magenta coupler, a red-sensitive layer containing a cyan coupler and a blue-sensitive layer containing a yellow coupler.
- a magenta color stain occurs even in the presence of an extremely small amount of thiourea or its derivative, for instance, a IO -IO g./l. color-developing solution thereof.
- it is nearly impossible to prevent such color stain since many of the thiourea derivatives have absorptive properties and the elimination thereof is very difficult.
- thiourea or its derivatives are absorbed on the leader belt and cannot be completely eliminated during the processing steps after bleach-fixing; that is, during the stages of washing, hardening, final washing and stabilizing. Therefore, thiourea or its derivatives, absorbed on the leader belt, enters into the color developing solution, resulting in color stain.
- R, and R are alkyl, hydroxyalkyl, aryl and allyl groups or they may be linkedtogether to-form a heterocyclic ring
- R is an alkyl,.hydroxyalkyl or allyl group when R and R, do not-form a heterocyclic ring
- the compound- (I) showed remarkable acceleration of bleaching reaction in every case where it is added to a bath between the color developin'g'and bleach-fixing, or to a bleach-fixing bath itself.
- Compound 7 Compound 1 may be synthesized in the conventional manner by heating ethylenediamine with carbon disulfide in a mixed solvent of water and alcohol (Cf. Roger Adams, Organic Synthesis published by John Wiley & Sons Co. Vol. 26, p. 34).
- Compound 2 and compound 3 are similarly synthesized by reacting the corresponding diamine with carbon sulfide.
- Compound 4 is obtained by reacting methyl isothiocyanate with N-methyl-ethanolamine in ether, distilling the ether and recrystallizing the residue from ethyl acetate.
- the amount of the foregoing compound to be added to bleach-fixing solution is from 0.1 g./l. to the minimum dissolving amount of each compound, preferably 0.3 g./l. to 5 g./l. These compounds may be used separately or together.
- the acceleration of bleaching reaction by the compound can also be observed when it is added to any of the processing solutions between the color development and bleach-fixing bath in an amount within the range mentioned above.
- EXAMPLE 2 Compounds l-9 were added to a color developing solution containing N-ethyl-N-fl-hydroxyethyl-p-phenylenediamine and dissolved completely. A color positive film was then treated with color developing solutions respectively to give the following results.
- magenta stain was formed.
- EXAMPLE 3 Compounds [-8 of example 1 were added to the following bleach-fixing solution by the amount of 2 g. per lOOO ml. respectively. 1,000 11 iron Salt of EDTA 34 g. Sodium Carbonate (monohydrate) H g. Boric Acid 45 g. Sodium Thiosulfalc g. Additive 2 g. Water to Make 1,000 ml. pH 6.8
- a color paper was exposed. developed, fixed and then passed through these bleach-fixing baths. The times required to remove the developed silver were shown in the table below.
- EXAMPLE 4 Compounds 1-7 of example 1 were added to the following stop fixing solution in an amount of l g. per 1000 ml. respectively.
- R and R each represents a member of an alkyl group, a hydroxyalkyl group, and aryl group and an allyl group, said R and R, can form together a heterocyclic ring
- R represents a member selected from the group consisting of an alkyl group, a hydroxyalkyl group and a an allyl group when R and R do not form a heterocyclic ring
