Description

Verfahren zur Herstellung von Lichtpausen und Photokopien Durch das Patent 458 825 ist ein Verfahren zur Herstellung von Lichtpausen und Photokopien geschützt, bei dem die als lichtempfindlicher Stoff verwendeten i # z-naphthochinon.-.4_sulfosauren Salze nach der Belichtung mit organischen, freie Aminogruppenenthaltenden Verbindungen entwickelt werden. In dem Patent 459796 ist dieses Verfahren. derart abgeändert, daß die Entwicklung in Gegenwart von Alkali mit Verbindungen bewirkt wird, welche eine saure Methylen-oder Methylgruppe enthalten. Als besondere Atisführungsform wird die Entwicklung des Bildes mit Ammoniakdämpfen für den Fall beschrieben, daß der lichtempfindliche und der entwickelnde Stoff gemeinsam dem Schichtträger einverleibt werden.Process for the production of blueprints and photocopies A process for the production of blueprints and photocopies is protected by patent 458 825, in which the i # z-naphthoquinone .- will. In the patent 459796 this method is. modified so that development is effected in the presence of alkali with compounds containing an acidic methylene or methyl group. As a special form of implementation, the development of the image with ammonia vapors is described in the event that the light-sensitive and the developing substance are incorporated into the substrate together.

Wie nun bei weiterer Bearbeitung dieses Gebietes gefunden. wurde, lassen sich als lichtempfindliche Stoffe auch die Substitutionsprodukte der i # z-Naphthochinon-4-sulfosäure, wie z. B. die Halogen-. Oxy-, Sulfousw. Derivate, mit dem gleichen Erfolge verwenden.As found in further processing of this area. became, the substitution products of the i # z-naphthoquinone-4-sulfonic acid, e.g. B. the halogen. Oxy-, sulfousw. Derivatives, use with the same success.

Beispiel. Ein mit einer Schicht von i # z-naphtho-cbino!n-4 # 6=disulfosaurem Ainmon und Resorcin versehenes Papier wird nach dem Belichten mit Ammoniakdämpfen entwickelt. Man erhält unmittelbar ein violettes Positiv, das nach kurzem Verweilen an der Luft in Rot übergeht.Example. One with a layer of i # z-naphtho-cbino! N-4 # 6 = disulfosaurem Ainmon and resorcinol-coated paper is exposed to ammonia vapors after exposure developed. A purple positive is obtained immediately, which after a short period of time turns red in the air.
