Description

Verfahren -der Tonung schwefelgetonter silberhaltiger Entwicklungs- und Kopierpapiere. Zusatz zum Patent 413360. Im Patent q.i336o wurde zur Goldtonung schwefelgetonter Entwicklungspapiere auf wenig komplexe Goldsalze Nachdruck gelegt. Es hat sich inzwischen gezeigt, daß auch stärker komplexe Gold- und Platinsalze verwertbar sind, ja sogar eine ruhigere Durchtonung erlauben als wenig komplexe Salze.Process of toning sulfur-toned silver-containing development and copy papers. Addition to patent 413360. In patent q.i336o was used for gold toning Sulfur-toned development papers put emphasis on less complex gold salts. It has meanwhile been shown that more complex gold and platinum salts can also be used are usable, and even allow a quieter through-toning than less complex ones Salts.

Besonders geeignet als Komplexsalzbil,dner- sind Thiocarbamid (Schwefelharnstoff), Rhodanalkali, Thiosulfat, auch Thiosinamin. Für Änderung des Röteltones mach Gravüretönen hin empfiehlt sich ein geringer Zusatz von Bleisalzen zu den Goldbädern. Auch gewöhnliche Tonfixiersalve und -bäder des Haridels sind beim Zusatz bzw. weiteren Zusätzen von Gold verwertbar.Particularly suitable as complex salts, thiocarbamide (urea sulphide), Rhodane alkali, thiosulfate, also thiosinamine. To change the red tone, use engraving tones a small addition of lead salts to the gold baths is recommended. Ordinary too Tonfixiersalve and baths of the Haridel are with the addition or further additions of Recyclable gold.
