Title: (DE) VERBESSERUNGEN IN BEZUG AUF EIN PHOTOGRAPHISCHES VERFAHREN.
(EN) IMPROVEMENTS RELATING TO A PHOTOGRAPHIC PROCESS.
(FR) TRAITEMENT PHOTOGRAPHIQUE AMELIORE.
Abstract:
(EN) In a photographic process which includes a developer and an amplification bath, a photographic material is passed from the developer to the amplification bath and an absorbing agent is used to treat the amplification bath to remove any carried over developing agent which may cause degradation of the amplification bath or the photographic material being treated.
(FR) Dans un traitement photographique comprenant un révélateur et un bain amplificateur, on fait passer le matériau de support photographique du révélateur au bain amplificateur et on utilise un agent absorbant pour traiter le bain amplificateur afin de supprimer toute trace résiduelle de révélateur pouvant occasionner la dégradation du bain amplificateur ou du matériau photographique traité.
