Definitions
- the invention relates to a developer for photosensitive film material according to the preamble of claim 1.
- Such developers are in a variety of forms on the market. They generally serve to convert, by a reducing agent (developing agent), silver ions or other suitable metal ions contained in the photosensitive layer and sensitized by exposure to light into metallic silver.
- a reducing agent developer agent
- silver ions or other suitable metal ions contained in the photosensitive layer and sensitized by exposure to light into metallic silver.
- the present invention is intended to provide a developer concentrate for photosensitive film material, which is distinguished by particularly good long-term stability under use conditions.
- the developer according to the invention has as further advantages that it is free of hydroquinone and of GDA (glutaraldehyde adduct). It is also characterized by a very high development activity. It also has excellent yield, especially in roll developing machines.
- the most important component in terms of quantity is the solvent. This is generally chosen so that it is compatible with the film layer to be developed, so it wets and allows an exchange of solutes with the film layer.
- a water-based solvent is suggested, which means that this solvent comprises predominantly or completely water.
- adjuvants may be added to the water which promote wetting of the film layer, optionally swelling of the film layer and later drying of the film layer.
- the developing agent serves to convert the metal ions of the photosensitive layer, insofar as they have been activated by light, into elemental metal.
- known developing agents include hydroquinone and other substances that are undesirable for environmental or potential health reasons.
- One class of reducing agent used in the developer of the present invention includes ascorbic acid and derivatives of ascorbic acid, especially salts thereof. These are particularly advantageous in terms of environmental protection.
- Development enhancers used in the invention include pyrazolidinone derivatives containing two nitrogen atoms in a five-membered ring.
- the five-membered ring may carry further aliphatic or aromatic groups.
- Preferred examples of such pyrazolidinone derivative developing agents are 4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidinone, 1-phenylpyrazolidin-3-one and 1-phenyl-4-methyl-3-pyrazolidinone. These substances are also known under the trade names Dimezone S, Phenidone A and Phenidone B.
- a development inhibitor is added to the developer.
- These are preferably alkali halides, in particular those with heavier anions, preferably potassium bromide or sodium bromide.
- the pH of the use solution be maintained within a given window of from about 8.5 to about 12, preferably from about 9.7 to about 11.2.
- alkalis preferably potassium hydroxide or sodium hydroxide.
- the pH can also be stabilized by salts of a weak acid in the desired alkaline range, in particular salts of weak organic or inorganic acids, preferably potassium carbonate, sodium tetraborate, sodium metaborate. You can also use mixtures of alkalis and salts.
- the development result is advantageously influenced if the developer is additionally added a complexing agent.
- complexing agents are preferably organic acids with small chain length, which contain nitrogen groups, more preferably additionally short aliphatic groups.
- Preferred complexing agents are diethyltriamine pentaethanoic acid (DTPA), ethylenediaminetetraethanoic acid (EDTA), hydroxyethylethylenediaminetriacetic acid (HEDTA) and nitrilotriethanoic acid (NTA) and salts of the aforementioned acids.
- a ready-to-use developer solution is adversely affected by oxidation in its properties.
- an antioxidant to the developer.
- Suitable for this purpose are generally not completely oxidized acids and salts thereof, in particular sulfites such as potassium sulfite, potassium hydrogen sulfite, potassium metabisulfite and sodium bisulfite.
- a solubilizer can be used.
- These may be polyhydric alcohols, in particular diols or glycols. Diethylene glycol and triethylene glycol are preferably used here.
- agents belonging to the group of azoles in particular of the benzotriazole, indazole, mercaptotetrazole and imidazole type), in particular 5-mercapto-1-phenyl-1,2,3,4-tetrazole (PMT ), 1-H-benzotriazole, 5-methylbenzotriazole, 6-nitrobenzimidazole, 5-nitroindazole.
- compositions of embodiments give an overview of the concentration in which the various components in a Use solution in grams per liter of working solution may be present.
- the concentrations are recommended, which are recommended if a considered component alone forms the corresponding agent. It is understood that it is also possible to use mixtures of substances that are equally suitable for the same component of the developer, in which case the amounts used are selected such that the corresponding overall effect is obtained. Thus, for example, according to the following table for the different complexing agents in each case the same amount used. In this case, one can then simply replace the omitted portion of a complexing agent with an appropriate amount of another complexing agent.
- Example 1 Developer for X-ray film processor
- concentration data in the above description and claims refer, as indicated, to one liter of working solution and not to the concentrate.
- concentrations in the concentrate are greater according to the prescribed dilution ratio for the concentrate. This dilution ratio is about 1.5 to 5 for a practical developer for roll-fed development machines, and about 0.5 to 1 for roll-free processors (film is moved around the edges by the tanks).
