Description

Verfahren zur Herstellung von lichtempfindlichen, kopierfähigen Schichten. Zusatz zum Patent 376385. Durch das Patent 376385 ist ein Verfahren geschützt worden, von positiven Bildern unmittelbar positive. Lichtpausen in der Weise herzustellen, daß man Diazoanhydride auf eine geeignete Unterlage aufträgt, die Schicht unter einem Positiv belichtet und alsdann das Bild durch Einführung in ein Bad von Phenolen oder Aminen entwickelt. Als Diazoanhydride werden die Diazoverbindungen der i-2 oder 2-i-Aminooxynaphthaline oder deren Derivate oder solche von heterocyklischen Verbindungen verwendet.Process for the production of photosensitive, copyable layers. Addition to patent 376385. A method has been protected by patent 376385 from positive images immediately positive. To produce blueprints in such a way that that one applies diazoanhydrides to a suitable base, the layer under exposed a positive and then the image by introducing it into a bath of phenols or amines developed. The diazo compounds of the i-2 or 2-i-aminooxynaphthalenes or their derivatives or those of heterocyclic ones Connections used.

Es ist nun weiter gefunden worden, daß man unter Anwendung solcher Diazoanhydride auch negative Bilder von einem Positiv oder positive Bilder von einem Negativ erhalten kann, wenn man den Diazoanhydriden Beizen und Alkali zusetzt. Mit derart auf geeigneter Unterlage aufgebrachten Schichten erhält man beim Belichten Farbstoffbildung, so daß die Zeichnung des Originals auf der lichtempfindlichen Schicht weiß bleibt, während die freien lichtdurchlässigen Stellen gefärbt werden.It has now been further found that using such Diazo anhydrides also include negative images of a positive or positive images of one Can be obtained negatively if pickling and alkali are added to the diazo anhydrides. With Layers applied in this way to a suitable substrate are obtained during exposure Dye formation, so that the drawing of the original on the photosensitive Layer remains white, while the free translucent areas are colored.

Ebenso unerwartet war, daß die Lichtempfindlichkeit solcher Emulsionen die des Chlorsilbers fast um das Doppelte übertrifft. Von einem Negativ wird auf diese Weise ein Positiv gewonnen, das zum Fixieren in Wasser mit oder ohne Alkali ausgewaschen wird. Das Farbstoffbild kann auch getont werden, z. B. mit Bichromat, Oxydationsmitteln u. a., die der Schicht auch einverleibt werden können.It was also unexpected that the photosensitivity of such emulsions that of silver chloride is almost twice as high. From a negative becomes on in this way a positive obtained, which can be fixed in water with or without alkali is washed out. The dye image can also be toned, e.g. B. with bichromate, Oxidizing agents, among other things, which can also be incorporated into the layer.

Der am Licht gebildete Farbstoff entspricht nicht einem normal gebildeten Azofarbstoff, da diese Diazoanhydride in wässeriger Lösung verkocht oder belichtet, kein Phenol oder Naphtol liefern, das mit der gleichen Diazoverbindung einen gleichen Farbstoff.-, wie in der Schicht, bildet. Mit diesem lichtempfindlichen Papier kann man von Positiven negative Kopien auch in der Weise gewinnen, daß man das lichtempfindliche Papier auf das Positiv legt und durch die lichtempfindliche Schicht belichtet. Der Papierstoff soll zu diesem Zweck transparent sein. Er kann auch durch Filme u. dgl. ersetzt werden. a Beispiel: i-Diazo-2-oxynaphthalin-q.-sulfosäure wirdmit4 Brechweinstein und Soda in der Emulsion versetzt und damit Papier oder Filme lichtempfindlich gemacht. Das Diazopapier kann auch erst unmittelbar vor Gebrauch mit Alkali behandelt werden. Nach der Belichtung wird das Bild in verdünnter Soda-Wasserlösung ausgewaschen.The dye formed in the light does not correspond to one formed normally Azo dye, since these diazo anhydrides are boiled or exposed to light in an aqueous solution, do not provide any phenol or naphthol which is the same with the same diazo compound Dye.-, as in the layer, forms. With this photosensitive paper you can Negative copies of positives can also be obtained in such a way that they are photosensitive Lays paper on the positive and exposes it through the light-sensitive layer. Of the Paper stock should be transparent for this purpose. He can also through films and the like. be replaced. a Example: i-Diazo-2-oxynaphthalene-q.-sulfonic acid becomes emetic tartar with4 and soda are added to the emulsion to make paper or films photosensitive. The diazo paper can also be treated with alkali immediately before use. After exposure, the image is washed out in a dilute soda water solution.
