Abstract: In a process and device for the regeneration of aqueous washing-out solutions and water-developable photosensitive recording materials, the washing-out solution (2) loaded with washed-out material is continuously purified by ultrafiltration, the filtrate (7) is recycled as washing-out solution to the developing machine (1) for re-use and the concentrate (8) with the washed-out material is added to the washing-out solution (2). The following arrangement can be used for carrying out the process: The overflow branch of the developing machine (1) is connected via an interposed tank (3), a pump (4) and a prefilter (5) to the ultrafiltration unit (6), while the filtrate outlet branch is connected to the developing machine (1) and the concentrate outlet branch is connected to the tank. This process ensures that the environment is not polluted by spent washing-out solution.

Abstract: Photopolymerizable recording materials which are suitable for the production of photoresist layers, and contain one or more thermoplastic vinyl polymers as the binder, one or more low molecular weight, ethylenically unsaturated, photopolymerizable compounds and one or more photoinitiators, with or without other, conventional additives and/or assistants, have excellent adhesion to metallic substrate surfaces if the binder employed is a vinyl polymer which possesses amino and/or imino groups.

Abstract: For work-up and regeneration of aqueous solutions containing polymers containing ionic groups and possibly further substances in dissolved form, as produced during the washing of exposed photosensitive recording materials for optical information fixing, small amounts of ionogenic organic flocculation auxiliaries are added to the aqueous solutions, and the resultant precipitate is separated off.
