Definitions

  • the invention relates to a photographic process of the kind in which a silver halide material 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.
  • GB-A-1,514,517 there is described a photographic development process wherein a photographic material is treated with a developer agent and subsequently passed to an in-line amplification bath comprising hydrogen peroxide.
  • the present invention is characterised in that the amplification bath is treated with an ion exchange resin to reduce the amount of available developer agent 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.
  • None of the prior art shows the use of ion exchange resins 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 100mls. of an 'RX' developer to 500mls of an amplifier suitable for use with low silver materials.
  • the formulae are as follows :
  • the absorbing agents all had an effect to a greater or lesser degree in reducing the amount of agent in the amplification bath.
  • suitable agent has to be made depending on the nature of the developer in each bath.
