Description
Verfahren zur Herstellung von lichtempfindlichen Schichten vermittels Ferrisalze, die aus einem Negativ ein Positiv ergeben Es ist gefunden worden, daß man lichtempfindliche Schichten, die aus einem Negativ ein Positiv ergeben,- vermittels Ferrisalze in der Weise herstellen kann, daß man die Ferrisalze mit Ketonen versetzt, die bei der Belichtung farbige Verbindungen ergeben.Process for the production of photosensitive layers by means of Ferric Salts That Make a Negative a Positive It has been found that light-sensitive layers, which turn a negative into a positive, - mediate Ferric salts can be produced by adding ketones to the ferric salts, which give colored compounds on exposure.
Zur Herstellung der Schicht werden als erste Komponente Ferriverbindungen benutzt, wie Ferriammoniumcitrat, -tartrat, -ohalat u. dgl., ferner Eisenchlorid und Ferrisulfat in Mischung.To produce the layer, ferric compounds are used as the first component used, such as ferric ammonium citrate, tartrate, ohalate and the like, also ferric chloride and ferric sulfate in a mixture.
Als zweite Komponente werden Ketone benutzt, die mit Ferrosalzen farbige Verbindungen eingehen. Als solche Verbindungen kommen Chinone in Betracht, z. B. (3-Naphthochinonsulfosäure, Nitrosoverbindungen bzw.Isonitrosoverbindungen von ß-Carbonylen aliphatischer, aromatischer oder aliphatischer-aromatischer Natur.The second component used is ketones, which are colored with ferrous salts Make connections. Quinones are suitable as such compounds, e.g. B. (3-naphthoquinone sulfonic acid, nitroso compounds or isonitroso compounds of ß-carbonyls aliphatic, aromatic or aliphatic-aromatic in nature.
Die genannten Fernverbindungen werden am Licht zu Ferroverbindungen reduziert und bilden mit der zweiten Komponente sofort sichtbaren Farbstoff.The above-mentioned long-distance connections turn into ferrous connections when exposed to light reduced and form immediately visible dye with the second component.
Man kann der Schicht Bindemittel, wie Gelatine, Stärke, ferner -Farbstoff aussalzende Körper und zusätzliche Beizen beimischen. Bei Zugabe von Silberverbindungen erhält man Kopien nach Art der Sepiapapiere. Gemäß dem vorliegenden Verfahren werden Bilder gewonnen, die den größten Teil der Färbung bereits während des Kopierens zeigen, so daß das Auswässern bzw. Entwickeln nur unterstützend und zur Entfernung der überschüssigen Chemikalien dient. Beispiel r 1 Teil Ferriammoniumcitrat wird mit 3 Teilen Acetylnitrosoketon unter Zugabe von aufgeschlossener Stärke und Bariumchlorid auf Papier aufgetragen. Nach dem Trocknen wird kopiert, wobei das Bild sofort entsteht, und dann gewässert. In gleicher Weise kann man Isonitrosopropionylaceton verwenden,--ferner Nitroso-(l-naphthol usw. Mit (3-Naphthochnon-q.-sulfosäure gewinnt man mehr grünliche Bilder.You can add binders such as gelatin, starch, and dye to the layer Mix in salting-out bodies and additional stains. When adding silver compounds copies are obtained in the manner of sepia papers. According to the present procedure will be Images obtained that did most of the coloring while copying show so that the washing out or developing is only supportive and for removal which is used for excess chemicals. Example r 1 part of ferriammonium citrate is with 3 parts of acetylnitrosoketone with the addition of digested starch and barium chloride applied to paper. After drying it is copied, whereby the picture is created immediately, and then watered. Isonitrosopropionylacetone can be used in the same way - furthermore Nitroso- (l-naphthol, etc. With (3-naphthochnone-q.-sulfonic acid, more greenish Pictures.
Nach dem Kopieren wird gewässert. Nachbeizen kann mit Bichromat o. dgl. erfolgen.After copying it is watered. Post-pickling can be done with dichromate or similar. the like.
