Description

Verfahren zur Herstellung von Lichtpausen und Photokopien. Es ist bekannt, daß i, 2-naphthochinon-4-sulfosaure Salze mit organischen Verbindungen, «-elche eine oder mehrere freie Aminogruppen enthalten, unter Abspaltung der Sulfogruppe sehr leicht farbige Chinonanile bilden.Process for making blueprints and photocopies. It is known that i, 2-naphthoquinone-4-sulfonic acid salts with organic compounds, «-Which contain one or more free amino groups, with elimination of the sulfo group very easily form colored quinone aniles.

Wie gefunden wurde, sind i, 2-naplithocliinon-4-sulfosaure Salze sehr lichtempfindlich, so daß sich der genannte Vorgang mit Vorteil zur Herstellung von gefärbten Photokopien, Lichtpausen u. dgl. verwenden läßt. Man macht Papier oder mit einer Gelatineschicht überzogenes Papier, Glas oder Film durch Behandeln mit Lösungen von i, 2-naplitliochinon-4-sulfosauren Salzen lichtempfindlich, belichtet, z. B. unter einer Zeichnung auf Pauspapier, und entwickelt mit organischen Verbindungen, welche eine oder mehrere i Aminogruppen enthalten, wobei unmittelbar ein positives Bild der Zeichnung entsteht.As has been found, 1,2-naplithocliinone-4-sulfonic acid salts are very photosensitive, so that said process is advantageous for the production of colored photocopies, blueprints and the like. One makes paper or paper, glass or film coated with a gelatin layer by treating with Solutions of i, 2-naplitlioquinone-4-sulfonic acid salts light-sensitive, exposed, z. B. under a drawing on tracing paper, and developed with organic compounds, which contain one or more amino groups, with a positive immediately Image of the drawing is created.

Beispiel i.Example i.

Ein mit einer zweiprozentigen Lösung von i, 2-naphthocliinoti-4-sulfosaurem Kalium getränktes und getrocknetes Papier wird unter einem Schwarz-Weiß-Positit- belichtet und danach in einer einprozentigen Lösung von salzsaurem Anilin entwickelt. Die vor der Belichtung geschützten Stellen erscheinen rot auf farblosem Grunde.One with a two percent solution of i, 2-naphthocliinoti-4-sulfonic acid Potassium soaked and dried paper is displayed under a black and white position exposed and then developed in a one percent solution of hydrochloric aniline. The areas protected from exposure appear red on a colorless background.

Beispiel e.Example e.

Papier wird begossen mit einer Gelatinelösung, welche i, 2-naphthochinon-4-sulfosaures Kali enthält. Nach dem Trocknen und Belichten wird mit einer einprozentigen wäßrigen Lösung von i-Methyl-2, 4-diaminobenzol entwickelt. Man erhält bordeauxrote Töne.Paper is doused with a gelatin solution containing 1,2-naphthoquinone-4-sulfosaures Contains potash. After drying and exposure, a one percent aqueous solution is used Solution of i-methyl-2, 4-diaminobenzene developed. Bordeaux-red tones are obtained.

Beispiel 3. Example 3.

Eine i, 2-naphthochinon-4-sulfosaures Kali enthaltende Gelatinelösung wird auf Glas gegossen. Nach dem Trocknen und Belichten wird mit einer Lösung von i-Amino-4-oxybenzol entwickelt. Man erhält violette Töne.A gelatin solution containing 1,2-naphthoquinone-4-sulphonic acid potassium is poured onto glass. After drying and exposure, a solution of i-Amino-4-oxybenzene developed. Purple tones are obtained.
