Description
Die üblichen Kohle- und Durchschreibpapiere auf Wachsbasis weisen, wie bekannt, immer noch den Mangel auf, daß sie nicht genügend griffrein sind. Beschmutzungen der Hände und Formulare lassen sich auch bei peinlicher Sauberkeit und Sorgfalt nie ganz vermeiden. Es wäre daher ein großer Fortschritt, wenn es gelänge, auf einfache Weise ein absolut griffreines Papier herzustellen, bei dem die Beschmutzungsgef ahr völlig beseitigt ist.The usual charcoal and carbonless papers based on wax, as is known, still have the Lack that they are not sufficiently clean. Leave soiling of hands and forms Never avoid each other completely, even with embarrassing cleanliness and care. It would therefore be a great step forward if it were possible to produce a paper with absolutely no grip in a simple manner, in which the dirt vessel ahr is completely eliminated.
Es sind zahlreiche Vorschläge gemacht worden, um dieses Ziel zu erreichen, jedoch hat es bisher an geeigneten Farbreaktionen zur Durchführung dieser Vorschläge gefehlt. Die bisher vorgeschlagenen Farbreaktionen zeigen alle den Nachteil, daß sie unter den Anwendungsbedingungen der Praxis entweder nicht farbintensiv sind oder nicht in ausreichendem Maße eintreten. Jedenfalls gibt es heute noch kein Aufzeichnungs- oder Vervielfältigungsmaterial auf der Basis einer Farbreaktion auf dem Markt, das den Anforderungen der Praxis in jeder Hinsicht entspricht.Numerous proposals have been made to achieve this goal, but so far there have been suitable ones There is no color reaction to carry out these proposals. The previously proposed color reactions all show the disadvantage that they either fail under the conditions of use in practice are intensely colored or do not occur to a sufficient extent. In any case, there is still no record or reproducing material based on a color reaction on the market that meets the requirements corresponds to practice in all respects.
Es wurde nun gefunden, daß die bei der Einwirkung von Säuren oder sauren Verbindungen auf Spirodipyrane entstehenden farbigen Produkte wegen ihrer außerordentlich hohen Farbintensität und der Einfachheit ihrer Bildung sich ausgezeichnet für die Herstellung eines griffreinen druckempfindlichen Aufzeichnungsmaterials zum Durchschreiben einer Schrift auf eine Unterlage eignen.It has now been found that the action of acids or acidic compounds on spirodipyrans resulting colored products because of their extraordinarily high color intensity and simplicity their formation is excellent for the production of a touch-free pressure-sensitive recording material suitable for copying writing on a pad.
Die Anwendung der genannten Verbindung kann in bekannter Weise, z. B. dadurch erfolgen, daß man ihre Lösung in einem nicht oder schwer flüchtigen Lösungsmittel in Form von feinen Tröpfchen in einer geeigneten Beschichtungsmasse dispergiert und mit dieser Masse ein sauer reagierende Stoffe enthaltendes Papier überzieht. Bei entsprechendem Schreibdruck gelangen die beiden Komponenten der Farbreaktion miteinander in Berührung, und es entsteht ein farbiges Schriftbild.The said compound can be used in a known manner, for. B. be done by their solution in a non-volatile or poorly volatile solvent in the form of fine droplets in a dispersed suitable coating mass and with this mass containing an acidic substance Paper coated. If the writing pressure is appropriate, the two components of the color reaction are achieved in contact with each other, and a colored typeface is created.
Man dispergiert 1 Teil einer 0,30/oigen Lösung von Spirodibenzopyran in Chlordiphenyl in 5 Teilen einer 20%igen Gelatoselösung in Wasser und beschichtet mit dieser Emulsion ein sauer reagierendes Rohpapier.Dispersing 1 part of a 0.3 0 / o solution of Spirodibenzopyran in Chlorodiphenyl in 5 parts of a 20% Gelatoselösung in water and coated with this emulsion an acidic base paper.
Man kann auch die beiden Komponenten der erfindungsgemäßen Farbreaktion jede für sich auf einem getrennten Blatt unterbringen und erhält so ein Vervielfältigungsmaterial, das ähnlich dem bekannten Kohlepapier verwendbar ist.You can also use the two components of the invention Place each color reaction on a separate sheet of paper and thus receive a Duplication material that can be used in a manner similar to the well-known carbon paper.
Man dispergiert 1 Teil einer 0,r°/oigen Lösung von Spirodinaphthopyran in Clordiphenyl in 5 Teilen Druckempfindliches Aufzeichnungsmaterial1 part of a 0.1 percent solution of spirodinaphthopyran in chlorodiphenyl is dispersed in 5 parts Pressure sensitive recording material

einer 2O°/oigen Gelatoselösung in Wasser und beschichtet mit dieser Emulsion ein neutral reagierendes Rohpapier.a 20% gelatin solution in water and coated with this emulsion a neutral reacting base paper.
Eine weitere Anwendung der erfindungsgemäßen Farbreaktion zur Herstellung eines griffreinen druckempfindlichen Aufzeichnungsmaterials besteht darin, daß ein Spirodipyran in Form einer Lösung in einem nicht oder schwer flüchtigen Lösungsmittel in eine poröse Kunststoffbeschichtung des Papiers eingelagert ist, aus der sie bei entsprechendem Schreibdruck auf ein untergelegtes saures Papier übertragen wird.Another application of the color reaction according to the invention for the production of a touch-free pressure-sensitive Recording material is that a spirodipyran in the form of a solution in a non-volatile or poorly volatile solvent in a porous plastic coating of the paper is stored, from which it is placed on an underlying acidic paper with appropriate writing pressure is transmitted.
Es besteht auch die Möglichkeit, ein Spirodipyran in einer aus Wachsen und Weichmachern zusammengesetzten Beschichtung unterzubringen und diese wie bei den üblichen Durchschreibpapieren durch Schreibdruck auf ein zur Auslösung der Farbreaktion geeignetes saures Papier zu übertragen. Man kann auch die eine Komponente der erfindungsgemäßen Farbreaktion in einer nicht oder schwer flüchtigen Flüssigkeit gelöst zum Tränken eines Bandes verwenden und erhält auf diese Weise ein nicht schmutzendes griffsauberes Schreibband, welches geeignet ist, ein Papier zu beschreiben, das die andere Farbbildnerkomponente enthält. Die genannten Beispiele zeigen, daß die erfindungsgemäße Farbreaktion in der mannigfaltigsten Weise zur Anwendung gelangen kann.There is also the possibility of a spirodipyran in a composed of waxes and plasticizers To accommodate coating and this as with the usual carbonless papers by writing pressure to be transferred to an acidic paper suitable for triggering the color reaction. One can also one component of the color reaction according to the invention in a non-volatile or poorly volatile liquid Use loosened to soak a tape and in this way get a non-soiling one Tight-grip writing tape, which is suitable for writing on a paper that contains the other color former component contains. The examples mentioned show that the color reaction according to the invention in the can be used in a variety of ways.
