KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gemäß Patent 142489 kann man die Alkalisalze des Glykokolls mit Vorteil als unschädlichen Ersatz der freien, kohlensauren oder flüchtigen Alkalien in den gebräuchlichen photographischen Entwicklern verwenden.According to patent 142489, the alkali metal salts of glycocolla can advantageously be classified as harmless Use substitutes for the free, carbonic or volatile alkalis in common photographic developers.
Weitere Versuche haben ergeben, daß man für den gleichen Zweck auch die Alkalisalze der am Stickstoff alkylierten Glykokolle verwenden kann.Further experiments have shown that the alkali salts can also be used for the same purpose who can use glycollates alkylated on nitrogen.
Die praktische Anwendung möge aus folgendem Beispiele ersehen werden:The practical application can be seen from the following example:
A. 12,5 g Pyrogallol und 75 g kristallisiertes
Natriumbisulfit werden in Wasser gelöst und die Lösung auf 500 ecm eingestellt.
!5 B. 20 g Methylglykokoll (Sarkosin) und 8 g Ätznatron (100 Prozent) werden zusammen in
Wasser gelöst und die Lösung auf 500 ecm eingestellt.A. 12.5 g of pyrogallol and 75 g of crystallized sodium bisulfite are dissolved in water and the solution is adjusted to 500 ecm.
5 B. 20 g of methyl glycol (sarcosine) and 8 g of caustic soda (100 percent) are dissolved together in water and the solution is adjusted to 500 ecm.
Gleiche Volumteile von A. und B. gemischt, geben einen gebrauchsfertigen Entwickler für die normal exponierte Bromsilbergelatineplatte. In obigem Beispiele kann das Pyrogallol ersetzt werden durch die entsprechende Menge irgend eines anderen der bekannten alkalisch wirkenden Entwickler, z. B. Hydrochinon, Brenzcatechin, p-Amidophenol, Adurol, Glycin, Edinol usw.; ferner kann das Methylglykokoll ersetzt werden durch die äquivalenten Mengen anderer am Stickstoff alkylierter Glykokolle, insbesondere durch Dimethylglykokoll, Monoä'thylglykokoll und Diäthylglykokoll.Equal parts by volume of A. and B. mixed, give a ready-to-use developer for the normally exposed silver bromide gelatin plate. In the above examples, the pyrogallol be replaced by the corresponding amount of any other of the known alkaline acting developer, e.g. B. hydroquinone, catechol, p-amidophenol, adurol, glycine, Edinol, etc .; Furthermore, the methyl glycol can be replaced by the equivalent amounts other glycocolls alkylated on nitrogen, in particular by dimethylglycocoll, monoethylglycocoll and diethyl glycocolla.
