Definitions

the invention relates to a photographic process of the kind in which silver halide materials carried on a photographic carrier material is treated with a developer to develop an image and is then passed to an amplification bath. Subsequent to the amplification bath, the material is passed to a fixing and washing stage.
the amplification bath itself has developer carried over into it which is transported on the material being processed and the presence of this developer builds up and shortens the life of the amplifier bath. In order to keep the bath up to the right strength it has to be replenished periodically to compensate for this build-up of developer.
the step is included of treating the amplification bath with an absorbing agent to remove or substantially reduce the amount of developer retained in the bath.
the absorbing agent is preferably an ionic exchange resin, which may be either cationic, anionic or neutral. In certain circumstances, a mixture of anionic and cationic resins may operate successfully.
the agent may comprise an activated carbon such as activated charcoal.
None of the prior art shows the use of absorbing agents in the tail-end of a photographic process which includes an amplification bath.
the following example illustrates the effect of different absorbing materials when used to remove the colour-developing agent when used in an amplification bath:
a simulated seasoned amplification bath was made by adding lOOmls. of an 'RX' developer to 500mls of an amplifier suitable for use with low silver materials.
the formulae are as follows :
CD3 8.Og water to 1.0 litre pH adjusted to 10.3 with potassium hydroxide solution
Amplifier hydrogen peroxide ( 100 vol) 30mls water to 1.0 litre
Activated charcoal 0.0+0.2g/l It will be seen from the above example that the absorbing agents all had an effect to a greater or lesser degree in reducing the amount of agent in the amplification bath. Clearly a selection of suitable agent has to be made depending on the nature of the developer in each bath. For the ' X'developer selected for this example there are five absorbing agents including both active charcoal and ion exchange resins which are wholly successful in removing all the developing agent.
