sich in hervorragender Weise zum Entwickeln des photographischen Bildes eignet. Die Substanz besitzt ein außerordentlich großes Entwicklungsvermögen und liefertis excellent for developing the photographic image. The substance has an extraordinarily great development potential and delivers

ίο sehr kläre Bilder. Die Anwendung von fixen Alkalien beim Entwickeln mit dieser Substanz ist nicht erforderlich, sondern sie entwickelt sehr kräftig bereits bei Gegenwart kohlensaurer Alkalien. Da das Oxyphenylglycinamid in Gegenwart von kohlensauren Alkalien leicht löslich ist, so lassen sich mit demselben hochkonzentrierte Vorratslösungen herstellen. Ein weiterer Vorzug ist die außerordentlich große Haltbarkeit der alkalisehen Lösung des vorgenannten Entwicklers, welche diejenige der bisher bekannten Entwickler übertrifft.ίο very clear pictures. The application of Fixed alkalis when developing with this substance is not necessary, but them develops very strongly even in the presence of carbonate alkalis. As the oxyphenylglycine amide is easily soluble in the presence of carbonate alkalis, highly concentrated stock solutions can be prepared with the same produce. Another advantage is the extremely long shelf life of the alkaline eyes Solution of the aforementioned developer, which is that of the previously known developers surpasses.

Das p-Oxyphenylglycinamid wird durch Einwirkung von Chloracetamid auf p-Amidophenol bei Gegenwart von salzsäurebindenden Mitteln gewonnen, wobei als solches Mittel auch p- Amidophenol selbst durch Anwendung eines Überschusses von demselben gebraucht werden kann.The p-oxyphenylglycine amide is by Effect of chloroacetamide on p-amidophenol in the presence of hydrochloric acid binding agents Means obtained, as such means also p-amidophenol itself by application an excess of it can be used.

Zur Herstellung der Entwicklerlösung löst man beispielsweise I g p-Oxyphenylglycinamid in 200 ecm Wasser unter Zusatz von 5 g Potasche und 5 g wasserfreiem Natriumsulfit und verwendet die so erhaltene Lösung direkt zum Entwickeln.To prepare the developer solution, for example, 1 g of p-oxyphenylglycine amide is dissolved in 200 ecm of water with the addition of 5 g of potash and 5 g of anhydrous sodium sulfite and uses the resulting solution directly for development.
