SOLUTIONS FOR A PHOTOGRAPHIC REVERSAL BATH AND PROCESSING METHOD FOR A PHOTOGRAPHIC COLOR REVERSAL FILM

摘要

The present invention relates to a concentrated solution for photographic reversal baths, and to a ready-to-use reversal solution, for limiting the growth of microorganisms and biofilm formation. The solutions comprise a chelating agent comprising an alkali metal salt of a phosphonic or phosphinic acid, and a biological growth control agent, said biological growth control agent comprising a mixture of at least one quaternary ammonium compound with short alkyl chain and at least one polymeric quaternary ammonium compound that is highly soluble in water, the total concentration of quaternary ammonium compounds being less than or equal to 0.5 g/l.
