Definitions
- the invention relates to a method for the preparation of concentrated photographic processing baths for photographic materials containing silver halides, such as developers and fixing baths, in a form such that the chemical components are present partially as solids and partially as liquids in the concentrate (such a mixture is commonly referred to as paste).
- liquid concentrates have the advantage of convenience in use; the disadvantages are, inter alia, the relatively high costs of packaging compared to powders, the need to use water-miscible organic solvents such as diethylene glycol and triethylene glycol, and the danger of freezing under winter conditions.
- a powder has the advantage that it permits a very high concentration.
- the disadvantages are the additional requirements which the chemicals have to meet (they must be solid, non-volatile substances), the formation of dust from the fine material during the dissolution procedure, the need to package chemicals separately and the more troublesome metering and mixing procedures compared to liquids.
- dust control furthermore has high priority; working with chemical mixtures which may cause dust therefore has to be avoided from the point of view of industrial hygiene and health.
- Organic polymers such as carboxymethylcellulose, gelatine, agar-agar, casein, alginates; polyvinyl alcohol and polyvinylpyrrolidinone or organic water-miscible solvents, such as methylcel- losolve, ethylcellosolve, diethylene glycol, triethylene glycol and polyethylene glycol, and their derivatives, appear to prevent the formation of large crystal lumps and thus have a favourable effect on the shelf life and the rate of dissolution of the concentrate.
- concentrations achievable are found to be even higher than those achievable via powder mixtures.
- Figure 1 shows an apparatus according to the invention, whereby it is possible, using a predetermined quantity of water, to squirt empty the containers which have been filled with paste in the factory, and to transfer the contents into a mixing vessel.
- the invention relates to a pump arrangement
- a pump arrangement comprising a pump (2), a line (3) connected to the pump housing and pro vided with one or more orifices (8) on its underside, a cutter (7) mounted on the pump shaft and two spaces (9 and 10) provided with a removable lid, and intended for the containers (A) and (B) filled with paste.
- a two-component developer concentrate having the following composition was prepared:
- a two-component fixing concentrate having the following composition was prepared:
