Die Wechselwirkung einiger Badkomponenten in einem (klassischen) Farbentwicklungsbad

Abstract

The separation of a color developer base on the surface of a color development bath is described, referred to in technical jargon (according to the degree of contamination) as «tar formation», which can occur when color development baths are not properly set. Here, temporarily difficult to dissolve sodium carbonate decahydrate, inadequate stirring and impure benzyl alcohol interact directly.
