Description

Gelatine für lichtempfindliche Silbersalzemulsionen und Verfahren zur Umarbeitung gewöhnlicher Gelatine In den Patenten 464 450 und 468 171 wurden Verfahren zur Herstellung photographischer Silbersalzemulsionen beschrieben, nach denen beim Emulsionsansatz Abbaustoffe von Proteinen pflanzlichen oder tierischen Ursprungs, erhalten durch alkalische, fermentative' oder saure Hydrolyse unter teilweiser Oxydation, anwesend sein sollen.Gelatine for light-sensitive silver salt emulsions and processes for reworking ordinary gelatine In patents 464 450 and 468 171 , processes for the production of photographic silver salt emulsions were described, according to which, in the emulsion approach, degradation substances of proteins of vegetable or animal origin, obtained by alkaline, fermentative or acidic hydrolysis with partial oxidation , should be present.

Wie nun gefunden wurde, kann man von vornherein Emulsionsgelatine erzeugen, welche die Eigenschaft besitzt, besonders hochempfindliche Silbersalzemulsionen zu ergeben, indem man solche Abbaustoffe von Proteinen gemäß den Patenten 464450 und _t68 171 bei der Gelatineberstellung dem Sude zu setzt. Man kann auch gewöhnliche Handelsgelatine, welche zunächst nicht zur Erzeugung photographischer Silbersalzemulsionen geeignet ist, dadurch zu einer vorzüglichen Emulsionsgelatine umarbeiten, daß man sie noch einmal mit Wasser aufschmilzt und mit einem Zusatz der genannten Abbaustoffe gut durchmischt. Die Gelatine kann dann gleich im gelösten Zustande weiterverarbeitet werden, oder sie kann auch erst wieder in der üblichen Weise in Tafel- oder andere Form gebracht werden. Die Handelsgelatine kann auch durch Baden der Gelatineblätter in Lösungen der Stoffe nachbehandelt und dann entweder wieder getrocknet oder gleich weiterverarbeitet werden.As has now been found, one can use emulsion gelatin from the outset produce, which has the property, particularly highly sensitive silver salt emulsions to be obtained by such breakdown substances of proteins according to patents 464450 and _t68 171 added to the brew when preparing the gelatine. One can also use ordinary ones Commercial gelatine, which was initially not used for the production of photographic silver salt emulsions is suitable, thereby reworking into an excellent emulsion gelatin that one it melts again with water and with an addition of the mentioned degradation substances well mixed. The gelatine can then be processed further in the dissolved state or it can only be used again in the usual way in table or other Be brought into shape. The commercial gelatin can also be made by bathing the gelatin sheets post-treated in solutions of the substances and then either dried again or immediately are further processed.

Die Art der zuzusetzenden Abbaustoffe und ihre Menge richten sich danach, welche Eigenschaften die mit der Gelatine herzustellenden Silbersalzemulsionen haben sollen.The type of degradation substances to be added and their amount depend on them then what properties the silver salt emulsions to be produced with the gelatin should have.
