Definitions
- a liquid composition for color photographic liquid processing concentrate comprising (1) benzyl alcohol or a homolog thereof, (2) diethylene glycol,
- This invention relates to a composition of a component package for a color photographic processing. More particularly, the invention relates to an improved composition of a component package for the processing containing benzyl alcohol used for the development of color photographic materials.
- a color photographic developer solution used for development of an exposed color photographic material contains generally a color developing agent which reduces silver halide having developing nuclei to form the oxidized developing agent which reacts with a coupler to form a dye, a preservative for preventing the deterioration of the developer solution by air oxidation, such as sodium sulfite or hydroxylamine; a suitable buffering agent to keep the pH of the solution constant and alkaline compounds for increasing the activity of the developing solution; an antifoggant for preventing the formation of undesirable fogs; and a solvent for couplers for accelerating the reaction of the developing agent with the couplers, such as benzyl alcohol.
- the developing solution may further contain a polyethylene glycol, a surface active agent, and an auxiliary developing agent.
- such a color photographic developing solution is prepared by mixing the necessary components before use and in other cases, commercially available prepared developer packages already containing the necessary components in correct weight ratios are used.
- the latter type of the developing composition is ordinarily called prepared developer chemicals or prepared developer packages.
- liquid-type prepared developer composition has the faults that the preservable period of it is short and in particular in a case of preparing the liquid-type prepared developer composition, the concentration thereof cannot be increased sufiiciently owing to the restriction in solubility of each component.
- a prepared developer composition is usually composed 3,814,606 Patented June 4, 1974 of two to four component groups for the purpose of the preservability and the convenience for lab-working. By dissolving all the component parts or packages in water, a final use developer solution is prepared.
- the prepared developer composition is ordinarily composed of a component part containing a color developing agent and sodium sulfite, a component part containing an alkali and a buffering salt, and a component part containing benzyl.
- This third composition part comprises a solvent for the coupler, hydroxylamine, a glycol, and water.
- benzyl alcohol is usually used but phenylethyl alcohol of w-phenylpropyl alcohol which is a homolog of benzyl alcohol may also be employed.
- Hydroxylamine for the composition has usually been used as the sulfate.
- the examples of the glycol are diethylene glycol, triethylene glycol, hexylene glycol and the like, and they are used for improving the solubility of the coupler solvent in water.
- the third component part has such faults that the preservation temperature which is an important characteristic of the prepared liquid developing composition is largely influenced by the component part and the preservable period of time of the component part is short.
- an object of this invention to provide a prepared processing composition which contains an aqueous solution of benzyl alcohol and hydroxylamine in a highly concentrated state and can be stably preserved for a long period of time.
- Another object of the invention is to provide a prepared composition for color photographic developer which can be stably preserved for a long period of time.
- Still another object of the invention is to provide concentrated compositions for color photographic developers which can be stably preserved for a long period of time.
- hydroxylamine sulfate has conventionally been employed in a color photographic developing solution, but the concentration of the component system is restricted to a very limited extent owing to the solubilities of benzyl alcohol, ethylene glycol, and water. And, the ratios of each component are also restricted from the solubilities of the components in each other, and hence the homogeneous solution can be prepared only in a definite range of the component ratios.
- DEG diethylene glycol
- the necessary amounts of DEG and Water for the preparation of the homogeneous liquid composition are more than 10 times that of hydroxylamine sulfate.
- the preservability of this type of concentrated liquid composition is remarkably influenced by the temperature of storage, and in particular, when the storage temperature-is lower than 10 C., the bad phenomena such as white precipitation deposition, and liquid-phase separation usually occur.
- the storage temperature-is lower than 10 C. the bad phenomena such as white precipitation deposition, and liquid-phase separation usually occur.
- the concentration near the critical value must inevitably be avoided if it is desired to expand the range of temperature for the preservation. Accordingly, it is also difficult to prepare the highly concentrated liquid composition.
- Hydroxylamine oxalate has an insufficient solubility and hence it is difiicult as in the case of hydroxylamine sulfate to increase the concentration of the liquid com position by using hydroxylamine oxalate. Moreover the use of hydroxylamine oxalate has the fault that the liquid composition is liable to be deteriorated by oxidation.
- Hydroxylamine base which has no acid has a sufiicient soluibility but is remarkably liable to be oxidized and hence the preservable period of time is short and the use of hydroxylamine is quite impractical.
- the use of various kinds of hydroxylamines is accompanied with the above-mentioned faults but, when the hydroxylamine is used as the hydrochloride, the improved liquid composition excellent in stability to the preservative temperature and to oxidation can be prepared.
- the ratio of DEG to water when the liquid composition containing hydroxylamine hydrochloride can be present as a homogeneous phase is shown in the following table.
- the liquid composition has the same photographic effect.
- the total amount of water and DEG in the liquid composition can not be reduced lower than 32 ml. when the sulfate is used, the amount can be reduced to 13 ml. when the hydrochloride is used according to the present invention.
- such a concentrated liquid composition for the mixed processing composition has a higher preservative stability and shows excellent resistance to the deterioration by temperature change (particularly the formation of insoluble matter at lower temperature) and oxidation during preservation.
- the temperature coefficient to the solubility in the case of using the hydrochloride is compared with that of the case of using the sulfate, the temperature coefiicient is reduced to about 30% in the proper contents of DEG, water, and benzyl alcohol.
- the liquid composition in which the hydrochloride has been used has a sufficient acid property as in the case of using the sulfate and has a sufiicient and practically usable stability to oxidation during preservation as compared with the case of using other salts of hydroxylamine such as the oxalate thereof or using hydroxylamine base.
- the liquid composition for producing 1 liter of the mixed developing solution contains usually 0.5-4 g. of hydroxylamine hydrochloride, 4-20 ml. of benzyl alcohol, 10-100 ml. of DEG and Water in the above-mentioned ratio and especially the liquid composition of this invention shows better effect when the total volume of the concentrated liquid is less than 50 ml.
- compositions containing benzyl alcohol and hydroxylamine hydrochloride of this invention may be conventional ones used generally for the purposes, which may be in the form of a liquid or solid and may be packaged in one or more parts.
- composition or part of the invention is in the liquid form, it may be only mixed, in use, with the other components or parts in the powder or liquid form.
- the composition containing a developing agent contains as the developing agent at least one pphenylenediamine type color developing agent such as N,N-diethyl-p-phenylenediamine,
- the liquid composition usually contains further at least one preservative such as sodium sulfite, potassium sulfite, or potassium pyrosulfite. In some cases, the liquid composition contains further an antifoggant such as 6-nitrobenzimidazole, etc.
- the developing agent-containing composition mentioned above is a liquid composition, it is in a state that the components have been dissolved, in high concentration, in a proper solvent such as water, a mixture of Water and triethylene glycol, a mixture of water and glacial acetic acid, or a mixture of water, glacial acetic acid and triethylene glycol.
- a proper solvent such as water, a mixture of Water and triethylene glycol, a mixture of water and glacial acetic acid, or a mixture of water, glacial acetic acid and triethylene glycol.
- the developing agent-containing composition for preparing 1 liter of the mixed developing solution contains usually about 1-12 g., preferably 4-8 g. of the developing agent and less than 5 g., preferably 0.52 g. of the sulfite.
- the alkali-containing group or composition contains 1-50 g. of an alkaline salt such as sodium carbonate, potassium carbonate, sodium hydroxide, potassium hydroxide, sodium metaborate, potassium metaborate, sodium tertiary phosphate, potassium tertiary phosphate, disodium hydrogen phosphate, dipotassium hydrogen phosphate, borax or mixture thereof.
- the composition further contains a buifering agent and a small amount of an alkali metal chloride, a bromide, an iodide, and aminopolycarboxylic acids such as ethylenediaminetetraacetic acid. This part may be in the form of a powder or an aqueous solution.
- compositions containing other components for the developer solution may be employed.
- the prepared processing liquid concentrates of this invention may be widely used for color photographic lightsensitive materials using silver halides, such as color papers, color negative films, reversal color films for color slides, reversal color papers for duplicates, color cinnefilms, and color positive films.
- the photosensitive silver halide may be silver chloride, silver bromide, silver iodobromide, silver chlorobromide, and silver chloroiodobromide and also the coupler contained in the light-sensitive material may be a so-called oil protective type coupler or a coupler with a ballasting group and a water-solubilizing group.
- EXAMPLE 1 The three component groups for preparing the developing solution are shown below.
- Composition A A:
- composition A had been highly concentrated, the transportation and handling of the compositions for preparing the final use developer solution were very easy. Also, the composition for the developer solution could be stably stored at temperatures higher than 5 C. and thus could be stored for a long period of time at ordinary storing conditions.
- EXAMPLE 2 A liquid developer solution was prepared by dissolving the following three components to make one liter.
- Composition A A:
- composition A could be stored stably for longer than 6 months at room temperature and also for longer than 2 months at high temperatures varying between 35" C. and 45 C. and further it could be stored for a short period of time at a low temperature of 5 C.
- EXAMPLE 3 The following liquid composition and powder compositions were dissolved in water to make 1 liter of developer solution in final use. The developing solution for color photographic films showed good photographic properties. The liquid and powdery compositions could be stored stably even at 0 C.
- Composition A A:
- EXAMPLE 4 When the developing agent in the composition C of Example 2 was replaced by 3 g. of 4-amino-N-ethyl-N- (fl-hydroxyethyl)-m-toluidine sulfate, the composition C could be further concentrated to 11 ml. and the developing solution prepared by dissolving the compositions in water showed the same photographic properties as in Example 2.
- EXAMPLE 5 The following compositions were dissolved in water to make 1 liter of developer solution for negative color photographic films having good photographic properties.
- Composition A A:
- Composition B is a composition of Composition B:
- a liquid composition for color photographic liquid processing concentrate comprising:
- composition contains from 0.5 to 4.0 parts by weight of hydroxylamine hydrochloride, from 4.0 to 20.0 parts by volume of benzyl alcohol, phenylethyl alcohol or w-phenylpropyl alcohol, and from 10.0 to 100 parts by volume of diethylene glycol in water, the volume ratio of said diethylene glycol to water ranging from 1.5 to 4.0.
- liquid composition of claim 1 further comprising a p-phenylenediamide type developing agent.
