Abstract

Eine Granulatmischung enthaltend eine granulierte Ent­ wicklersubstanz, eine granuliertes Oxidationsschutzmittel und eine granulierten Alkalispender, wobei die granu­ lierte Entwicklersubstanz kugelförmig ist und einen mittleren Teilchendurchmesser ≧ 150 µm aufweist, und wobei 80 % der Körner innerhalb eines Bereiches liegen, der vom gewünschten Korndurchmesser um nicht mehr als ± 100 µm abweicht, ist nicht staubend, rieselfähig, in wasserdampfdichter Verpackung unbegrenzt haltbar und löst sich in kürzester Zeit auf. A mixture of granules containing a granulated ent winding substance, a granular antioxidant and a granulated alkali dispenser, the granu lated developer substance is spherical and one has average particle diameter ≧ 150 microns, and where 80% of the grains are within a range of the desired grain diameter by no more than Deviates ± 100 µm, is not dusty, free-flowing, in Water vapor tight packaging has an unlimited shelf life and dissolves in no time.
