1 & N.0» 33061 - Werkwijze voor het bereiden van fotobad-concentraten in brijvora, werkwijze ter verwerking van dergelijke concentraten tot gebruiksklare fotografische verwerkingsbaden, een voor deze verwerking geschikte inrichting alsmede een tot deze inrichting behorende pompopstelling.-51 & N.0 »33061 - Method for preparing photo bath concentrates in slurry, method for processing such concentrates into ready-to-use photographic processing baths, a device suitable for this processing and a pump arrangement belonging to this device.
De uitvinding heeft betrekking op een werkwijze voor de bereiding van geconcentreerde fotografische verwerkingsbaden voor zilverhalogeni-de-bevattende fotografische materialen, zoals ontwikkelaars en fixeer-baden, in een zodanige vorm dat de chemische componenten ten dele vast 10 en ten dele als vloeistof in het concentraat aanwezig zijn (een dergelijk mengsel wordt veelal als brij aangeduid).The invention relates to a process for the preparation of concentrated photographic processing baths for silver halide-containing photographic materials, such as developers and fixing baths, in such a form that the chemical components are partly solid and partly as liquid in the concentrate are present (such a mixture is often referred to as a slurry).
Het is algemeen bekend dat de concentraties van de diverse componenten in een fotografisch verwerkingsbad binnen betrekkelijke nauwe begrenzingen dienen te liggen om een produkt met optimale fotografische 15 eigenschappen te verkrijgen; zie bijvoorbeeld het boek van L.F.A. Mason "Photographic Processing Chemistry" (The Focal Press, London, 2nd edition, 1975). Het belangrijkste oplosmiddel bij het verwerken van lichtgevoelig materiaal op basis van zilverhalogeniden is water. Hierin kunnen de meeste anorganische zouten goed in oplossing gebracht worden, terwijl 20 de oplosbaarheid in water van de in deze tak van fotografie gebruikelijke organische chemicaliën, zoals ontwikkelstoffen en sluierwerende stof- i fen, ook voldoende groot is.It is well known that the concentrations of the various components in a photographic processing bath must be within relatively narrow limits to obtain a product with optimal photographic properties; see, for example, the book by L.F.A. Mason "Photographic Processing Chemistry" (The Focal Press, London, 2nd edition, 1975). The main solvent in the processing of photosensitive material based on silver halides is water. Most inorganic salts can be dissolved well herein, while the water solubility of the organic chemicals customary in this branch of photography, such as developing agents and anti-fog agents, is also sufficiently great.
Een groot bezwaar van gebruiksklare oplossingen is echter dat het watergehalte ervan hoog is, waardoor een belangrijk deel van de hand-25 ling-, transport- en opslagkosten, welke gemaakt dienen te worden om het produkt van fabrikant naar gebruiker over te brengen op rekening van het water geboekt kunnen worden. Mede gezien het feit dat degene, die de verwerking van het fotografische materiaal uitvoert, normaliter ook de beschikking heeft over water, ligt het voor de hand om aan de gebruiker 30 een zodanig mengsel van stoffen aan te bieden, dat hieruit door toevoegen van of oplossen in een aangegeven hoeveelheid water het fotobad op eenvoudige wijze samen te stellen is.A major drawback of ready-to-use solutions, however, is that their water content is high, which means that an important part of the handling, transport and storage costs, which must be incurred to transfer the product from manufacturer to user on account of the water can be booked. Also in view of the fact that the person who carries out the processing of the photographic material normally also has access to water, it is obvious to offer the user 30 such a mixture of substances that it can be added or dissolved the photo bath is easy to assemble in a specified amount of water.
Alhoewel het in principe voor de gebruiker mogelijk is om zelf zijn fotobaden aan de hand van receptuur aan te zetten, kleven hieraan in de 35 praktijk een aantal bezwaren. Industriële preparaten zijn veelal tot stand gekomen via uitgebreide onderzoek- en ontwikkelingsprogramma’s en met gebruikmaking van beschermde en/of moeilijk te verkrijgen grondstoffen, waardoor dergelijke receptuur niet zonder meer vrij beschikbaar is.Although it is in principle possible for the user to switch on his photo baths himself on the basis of a recipe, there are a number of drawbacks in practice. Industrial preparations have often been developed through extensive research and development programs and using protected and / or hard-to-obtain raw materials, so that such a recipe is not simply freely available.
De volgens gepubliceerde, niet-beschermde receptuur samengestelde foto-40 baden zijn dan ook veelal verre van optimaal qua fotografische eigen- 8501659 «4r 2 schappen.The photo-40 baths composed according to published, unprotected formulations are therefore often far from optimal in terms of photographic properties.
In het eerder geciteerde boek van L.F.A. Mason wordt op blz. 141 ingegaan op de twee belangrijkste soorten samengestelde ontwikkelaars en regeneratiebaden, te weten de vloeibare concentraten en de poedermeng-5 seis. De vloeibare concentraten hebben als voordeel het gemak in gebruik, als nadelen zijn onder meer te vermelden de relatief hoge kosten van verpakking ten opzichte van de poeders, de noodzaak tot gebruik van water-mengbare organische oplosmiddelen, zoals di- en triethyleenglycol, en de kans op bevriezen onder winterse omstandigheden.In the previously quoted book by L.F.A. On page 141, Mason discusses the two main types of composite developers and regeneration baths, namely the liquid concentrates and the powder mix. The liquid concentrates have the advantage of ease of use, the disadvantages include the relatively high cost of packaging compared to the powders, the need to use water-miscible organic solvents, such as di- and triethylene glycol, and the chance of on freezing under winter conditions.
10 Een poeder heeft het voordeel dat dit een zeer hoge concentratie mogelijk maakt. Als nadelen zijn te noemen de extra aan de chemicaliën te stellen eisen (het moeten vaste, niet-vervloêiende stoffen zijn), het stuiven van het fijne stof tijdens de oplosprocedure, de noodzaak om chemicaliën apart te verpakken en de ten opzichte van vloeistoffen moei-15 lijkere doseer- en mengprocedures. In de chemische en aanverwante industrie heeft stofbestrijding bovendien een hoge prioriteit; het werken met mogelijk stuivende chemische mengsels dient vanuit het oogpunt van industriële hygiëne en veiligheid derhalve vermeden te worden.10 A powder has the advantage that it allows a very high concentration. Disadvantages include the additional requirements to be imposed on the chemicals (they must be solid, non-flowable substances), the dusting of the fine dust during the dissolving procedure, the need to pack chemicals separately and the difficulties with regard to liquids. 15 more similar dosing and mixing procedures. In addition, dust control has a high priority in the chemical and related industry; working with potentially dusty chemical mixtures should therefore be avoided from the point of view of industrial hygiene and safety.
In de moderne fotografische vakliteratuur komt men het ontwikkel-20 concentraat in brijvorm volgens Huebl, zoals deze in de oude fotografische literatuur, zoals bijvoorbeeld het "Ausführliches Handbuch der Photographie" onder redactie van Prof. Dr J.M. Eder en Dr Lueppo-Cramer (dritter Band, zweiter Teil, Verlag von Wilhelm Knapp, 1930) op pagina 123 beschreven is, niet meer tegen. Deze ontwikkelaar bevat als ontwik-25 kelstof "glycine" oftewel para-hydroxyfenylaminoazijnzuur en wordt als volgt bereid: 50 g natriumsulfiet-7-water wordt in 80 ml heet water opgelost; vervolgens wordt 20 g "glycine" toegevoegd en daarna wordt langzaam 110 g kaliumcarbonaat toegevoegd. Bij deze laatste handeling ontstaat onder een kooldioxide-ontwikkeling 150 ml van een goed-houdbare 30 brij. Om hieruit gebruiksklare ontwikkelaar te maken, neemt men van de brij, die eerst goed opgeroerd moet worden, 1 vol.dl en verdunt dit met 15 vol.dln water. Toch is deze concentraatvorm qua toepassingen beperkt gebleven tot de glycine-brij volgens Huebl, daar de nadelen zoals de noodzaak tot oproeren en het wat moeilijker afmeten van volumina duide-35 lijk niet tegen de voordelen hebben opgewogen. Daarnaast is "glycine" als ontwikkelstof al decennia lang achterhaald door andere ontwikkel-stoffen, zoals de van fenyleendiamine afgeleide fijnkorrel-ontwikkel-stoffen. Een ander belangrijk praktisch nadeel van de brijvorm volgens Huebl is verder het feit, dat er zich bij veroudering (opslag) vrij gro-40 te, harde en nauwelijks in oplossing te brengen kristallen vormen.In the modern photographic literature, the developing concentrate is slurried according to Huebl, as it is in the old photographic literature, such as for instance the "Ausführliches Handbuch der Photographie" edited by Prof. dr. Dr J.M. Eder and Dr Lueppo-Cramer (Dritter Band, Zweiter Teil, Verlag von Wilhelm Knapp, 1930) on page 123 is described, no longer against it. This developer contains "glycine" or para-hydroxyphenylaminoacetic acid as developing substance and is prepared as follows: 50 g of sodium sulfite-7 water are dissolved in 80 ml of hot water; then 20 g of "glycine" is added and then 110 g of potassium carbonate are slowly added. In the latter operation, 150 ml of a long-life slurry are formed under a development of carbon dioxide. To make this ready-to-use developer, one part of the slurry, which must first be stirred well, is taken and diluted with 15 parts by volume of water. Still, this form of concentrate has been limited in applications to the Huebl glycine slurry, since the drawbacks such as the need to stir and the more difficult measurement of volumes have clearly not outweighed the benefits. In addition, "glycine" as a developing agent has been obsolete for decades by other developing agents, such as the fine grain developing agents derived from phenylenediamine. Another important practical drawback of the slurry according to Huebl is furthermore the fact that upon aging (storage) fairly large, hard and hardly soluble crystals are formed.

Er werd nu gevonden dat het zeer wel mogelijk is alle in de fotografische- en reprografische industrie gangbare verwerkingsbaden voor zilverhalogeniden, zoals ontwikkelbaden, regeneratiebaden, rejuvenatie-baden, stopbaden, fixeerbaden, bleekbaden, bleekfixeerbaden, versterkers 5 en verzwakkers in een stabiel en houdbaar concentraat in brijvonn te brengen. Essentieel hierbij is de toepassing van een viscositeitverho-gend en kristalgroei-remmend middel. Het is uit de literatuur bekend dat bepaalde polymere verbindingen via adsorptie aan het kristaloppervlak agglomeratie van kristallen tegengaan. Evenzo is het bekend dat stoffen 10 uit bepaalde klassen van wateroplosbare organische oplosmiddelen een stabilisatie van het kristaloppervlak bewerkstelligen, waardoor processen zoals agglomeratie sterk vertraagd worden; zie bijvoorbeeld het boek van A.L. Smith (ed.): "Partiele Growth in Suspensions" (Academie Press,It has now been found that it is quite possible to use all processing baths for silver halides common in the photographic and reprographic industry, such as developer baths, regeneration baths, rejuvenation baths, stop baths, fixation baths, bleach baths, bleach fixation baths, builders 5 and attenuators in a stable and durable concentrate. in broth. Essential here is the use of a viscosity increasing and crystal growth inhibiting agent. It is known from the literature that certain polymeric compounds prevent agglomeration of crystals via adsorption on the crystal surface. Likewise, it is known that substances from certain classes of water-soluble organic solvents effect stabilization of the crystal surface, thereby greatly slowing down processes such as agglomeration; see, for example, the book by A.L. Smith (ed.): "Partial Growth in Suspensions" (Academy Press,
London, 1973). Organische polymeren zoals carboxymethylcellulose, gela-15 tine, agar-agar, caseine, alginaten, polyvinylalcohol en polyvinylpyrro-lidinon of organische met water mengbare oplosmiddelen, zoals methyl- en ethylcellosolve en di-, tri- en polyethyleenglycol en de hiervan afgeleide derivaten, blijken de vorming van grote kristalbonken te voorkomen en hebben aldus een gunstig effekt op de houdbaarheid en de oplossnel-20 heid van het concentraat. De te bereiken concentraties blijken zelfs hoger te liggen dan die welke via poeder-mengsels te bereiken zijn.London, 1973). Organic polymers such as carboxymethyl cellulose, gelatin, agar agar, casein, alginates, polyvinyl alcohol and polyvinylpyrrolidinone or organic water-miscible solvents, such as methyl and ethyl cellosolve and di-, tri- and polyethylene glycol and their derivatives. Prevent the formation of large crystal bumps and thus have a favorable effect on the shelf life and dissolution rate of the concentrate. The concentrations to be achieved appear to be even higher than those achievable via powder mixtures.
Voorts werd gevonden dat de inhoud van met de brij af gevulde houders in een speciaal daarvoor ontwikkeld handmatig te bedienen of automatisch werkende inrichting via uitspuiten en overbrengen in een mengvat 25 met een vooraf vastgestelde hoeveelheid water zich op eenvoudige wijze in zijn geheel laat oplossen tot een gebruiksklare oplossing. Overeenkomstig dit aspect van de vinding zijn dus de bezwaren tegen de noodzaak tot homogeniseren (het oproeren) en de te verwachten moeilijkheden bij het afmeten van de brij-volumina voor de gebruiker geheel en al verval-30 len.Furthermore, it has been found that the contents of containers filled with the slurry in a specially developed manually operated or automatic operating device can be dissolved in a simple manner, by spraying and transferring into a mixing vessel 25 with a predetermined amount of water, to a whole. turnkey solution. Thus, in accordance with this aspect of the invention, the objections to the need for homogenization (stirring) and the anticipated difficulties in measuring the slurry volumes for the user have been completely eliminated.
In fig. 1 is een inrichting volgens de uitvinding weergegeven, waarmede het mogelijk is met een vooraf vastgestelde hoeveelheid water de fabrieksmatig met brij af gevulde houders leeg te spuiten en in een mengvat over te brengen.Fig. 1 shows an apparatus according to the invention, with which it is possible to empty the containers filled with slurry from the factory with a predetermined amount of water and to transfer them to a mixing vessel.
35 De werking van de inrichting kan als volgt worden weergegeven:35 The operation of the device can be illustrated as follows:
Een met de Instructies overeenkomende hoeveelheid water wordt in het mengvat (1) gebracht. Vervolgens worden de met brij gevulde houders (A j en B) in de daarvoor bestemde, van losneembare deksels voorziene ruimten (9 en 10) gebracht. Dan wordt de pomp (2) ingeschakeld, waardoor het wa-40 ter door een leiding (3) via spuitkoppen (4) en (5) onder hoge druk de 8501659 4An amount of water corresponding to the Instructions is placed in the mixing vessel (1). The containers filled with mash (A j and B) are then placed in the spaces (9 and 10) provided with detachable lids. Then the pump (2) is switched on, so that the water flows through a pipe (3) via nozzles (4) and (5) under high pressure the 8501659 4

brij uit de houders spuit. Het water-brijmengsel valt onder invloed van de zwaartekracht in het mengvat, hierbij een in een behuizing (6) aangebracht snelronddraaiend mes (7) passerend, welk mes als taak heeft eventuele nog in de brij aanwezige klonten te verkleinen. In de behuizing 5 (6) bevinden zich een of meer openingen (8), die de verbinding vormen tussen de behuizing (6) en het mengvat (1). Op bovengenoemde wijze wordt voorkomen dat er te grote brokstukken in het mengvat terecht komen. Door namelijk de zeer intensieve menging in de behuizing (6) zullen klonten en brokstukken via oplossing al spoedig zodanig verkleind zijn, dat ze 10 alsnog via de gaten in de behuizing naar het mengvat kunnen gaan. In het mengvat vindt wel een roering plaats, maar deze is minder intensief dan in de genoemde behuizing. Nadat de brij in het mengvat volledig in oplossing is gegaan, kan de aldus verkregen oplossing direkt als fotografisch verwerkingsbad worden ingezet.squeeze the containers out of the container. The water-slurry mixture falls under the influence of gravity into the mixing vessel, passing a fast-rotating knife (7) arranged in a housing (6), the task of which is to reduce any lumps still present in the slurry. In the housing 5 (6) there are one or more openings (8), which form the connection between the housing (6) and the mixing vessel (1). In the above manner it is prevented that too large debris ends up in the mixing vessel. Namely, because of the very intensive mixing in the housing (6), clumps and debris will soon be reduced in solution so that they can still go through the holes in the housing to the mixing vessel. Agitation does take place in the mixing vessel, but it is less intensive than in the said housing. After the slurry has completely dissolved in the mixing vessel, the solution thus obtained can be used directly as a photographic processing bath.
15 Tenslotte heeft de uitvinding betrekking op een pompopstelling om vattende een pomp (2), een aan het pomphuis verbonden leiding (3), welke van twee spuitkoppen (4) en (5) is voorzien, een behuizing (6), welke aan de onderzijde van een of meer openingen (8) is voorzien, een op de pompas aangebracht mes (7) alsook twee van een losneembare deksel voor-20 ziene ruimten (9) en (10), bestemd voor de met brij gevulde houders (A) en (B).Finally, the invention relates to a pump arrangement comprising a pump (2), a pipe (3) connected to the pump housing, which is provided with two nozzles (4) and (5), a housing (6), which is attached to the bottom side is provided with one or more openings (8), a blade (7) mounted on the pump shaft and two spaces (9) and (10) provided with a detachable cover, intended for the slurry-filled containers (A) and B).
