Description

Verfahren zur Blautonung photographischer Silberbilder vermittels eines einzigen Tonungsbades Um schwarze photographische Silberbilder in blaue Bilder zu verwandeln, benutzt man chemische Tonungsbäder, die neben rotem Blutlaugensalz ein Eisenoxydulsalz (z. B. Eisenammoniakalaun) und eine geringe Menge Säure enthalten.Process for the blue toning of photographic silver images by means of a single toning bath To convert black photographic silver images into blue images To transform, one uses chemical toning baths, in addition to red blood liquor salt contain an iron oxide sulfate (e.g. iron ammonia alum) and a small amount of acid.

Die Blautonung.vermittels solcher Bäder kann entweder so ausgeübt werden, daß in dem ersten Bade eine Bleichung des Silberbildes erzielt wird und dann in einem zweiten Bade die Bilder blau getont werden, oder aber, daß nur !ein Tonbad verwandt wird, welches die Bilder gleichzeitig bleicht und blau tont.The blue toning by means of such baths can either be exercised in this way that a bleaching of the silver image is achieved in the first bath and then in a second bath the pictures are toned blue, or else that only! Tonbad is used, which bleaches the pictures and tones them blue at the same time.

Blautonungsvorschriften mit zwei Bädern sind schon beschrieben worden, wobei das zweite Bad Bromkali, enthält. Diese Bäder tonen mit Bromkalizusatz ungefähr ebenso schnell wie ohne Bromkalizusatz.Blue toning regulations with two bathrooms have already been described, the second bath containing potassium bromide. These baths tone roughly with the addition of calcium bromide just as quickly as without the addition of calcium bromide.

Die Geschwindigkeit, mit der das Silberbild in ein Eisenblaubild verwandelt wird, ist bei der Einbadtonung gering, was besonders dann von großem Nachteil ist, wenn bei Diapositiven oder Filmkopien eine vollkommene Durchtonung erreicht werden soll.The speed with which the silver image is transformed into an iron blue image is low with the one-bath tinting, which is particularly a great disadvantage, when perfect toning is achieved with slides or film copies target.

Man arbeitet z. B. mit einem Tonungsbad der nachstehenden Zusammensetzung: Lösung I: io g Ferricyanl@alium, i,3 ccm Kaliumbichromatlösung (i ofo ), i ooo ccm Wasser, Lösung Il. io,6g Eisenammoniakalaun, 5oo ccm Wasser,: Lösung III : i 2, 5 g Oxalsäure, 50o ccm Wasser.One works z. B. with a toning bath of the following composition: Solution I: 10 g Ferricyanl @ alium, 1.3 cc potassium dichromate solution (1 ofo), 100 cc Water, solution II. io, 6g iron ammonia alum, 5oo ccm water ,: solution III: i 2, 5 g oxalic acid, 50o cc water.

i Teile Lösung I und i Teil Lösung Il und i Teil Lösung III ergeben die Gebrauchslösung.i parts of solution I and i part of solution II and i part of solution III result the ready-to-use solution.

Tont man mit diesem Bade eine kräftige Silberkopie, so braucht man zur Durchtonung, d. h. bis auch die am Filmträger liegenden Silberteile blau getont sind, etwa i o Minuten.If you tone a strong silver copy with this bath, you need it for toning, d. H. until the silver parts lying on the film carrier are also toned blue are about 10 minutes.

Es wurde nun gefunden, daß ein Zusatz von Bromkali die Tonungsgeschwindigkeit dieses Blaubades sehr erhöht. Setzt man zu obigem Bad z % Bromkalium hinzu, so ist die Durchtonung desselben Bildes, wie es oben verwendet wurde, statt in i o Minuten bereits in 31/2 bis q. Minuten vollendet.It has now been found that the addition of potassium bromide increases the toning speed this blue bath is greatly enhanced. If one adds z% bromopotassium bromide to the above bath, so is the toning of the same image as used above instead of 10 minutes already in 31/2 to q. Minutes completed.
