Korrekturflüssigkeit zum Entfernen von Markierungen und Durchschriften auf ParbreaktionspapierenCorrection fluid for removing markings and copies on parbreaction papers
Schriften und Schriftzeichen sowie Markierungen aller Art, die mit Hilfe von Farbreaktionssystemen unter Verwendung von Parbreaktionspapieren erstellt worden sind, sind bisher nicht wie z. B. Schriften und Markierungen aus Bleistift, Tinte, Tusche, Kugelschreiber, Faserschreiber usw. korrigierbar. Ein einmal entstandener Fehler (Schreibfehler) war nicht sauber·abzuändern.-Fonts and characters as well as markings of all kinds that are made with the help of color reaction systems under Use of Parbreaktionspapieren have been created, are not so far such. B. Fonts and markings Can be corrected using pencil, ink, Indian ink, ballpoint pen, fiber pen, etc. A once created Error (spelling mistake) could not be changed properly.
Die Erfindung hat es sich zur Aufgabe gestellt, eine Korrekturmöglichkeit bzw. die Möglichkeit zur Beseitigung von Schreibfehlern in Schriftstücken, die mit Hilfe von Farbreaktionspapieren erstellt worden sind, zu erschaffen.The invention has set itself the task of providing a possibility of correction or the possibility of elimination of spelling mistakes in documents that have been created with the help of color reaction papers.
Es sind Neutralisierungsmittel bekannt, mit deren Hilfe Farbreaktionssysteme partiell, nämlich regional, unwirksam gemacht werden können, so daß an diesen Stellen die Farbreaktion nicht eintritt. Solche Neutralisierungsmassen enthalten vornehmlich quarternäre Ammoniumverbindungen und aliphatische oder aromatische Amine einzeln oder in Mischungen untereinander. Es hat sich gezeigt, daß diese Stoffe auch gut geeignet sind zur Verwendung als Korrekturmitter zur Beseitigung von Schreibfehlern, insbesondere, wenn man sie nicht nur in Wasser löst, sondern zusätzlich organische Lösungsmittel aus der Gruppe der Amide, wie Formamid, Dimethylformamid, Hexamethylphosporsauretriamid, hinzufügt·und diese Lösung dann aus einem Faserschreiber heraus auf die Fehlerstelle streicht. Es entsteht dannNeutralizing agents are known with the help of which color reaction systems are partially, namely regionally, ineffective can be made so that the color reaction does not occur at these points. Such neutralizing masses mainly contain quaternary ammonium compounds and aliphatic or aromatic amines individually or in mixtures with one another. It has been shown that this Substances are also well suited for use as correction tools to remove spelling mistakes, especially if you not only dissolve them in water, but additionally organic solvents from the group of amides, such as formamide, dimethylformamide, hexamethylphosphoric acid triamide, adds · and then this solution from a fiber-tip pen strokes out on the point of failure. It then arises

eine Desorption des CVL (Kristallviolettlakton). Das adsorbierte, gefärbte CVL wird durch die stärker adsorbierenden quarternären Ammoniumverbindungen oder Amine verdrängt und in die farblose Form übergeführt.a desorption of the CVL (crystal violet lactone). The adsorbed, colored CVL is replaced by the more strongly adsorbing Quaternary ammonium compounds or amines displaced and converted into the colorless form.
