Abstract
Description
Die Erfindung betrifft ein mehrschichtiges Korrekturmaterial auf einer silikonisierten Trägerfolie, das ohne die Verwendung von organischen Lösungs- oder Suspensionsmitteln herstellbar ist sowie ein Verfahren zu dessen Herstellung und seine Verwendung.The invention relates to a multilayer correction material on a siliconized carrier film, which without the Use of organic solvents or suspending agents is producible and a method for its production and its use.
Es ist bekannt, Schreib- oder Tippfehler bzw. fehlerhafte mögliche Darstellungen mit pigmentierten flüssigen Systemen zu überdecken und nach Trocknung gegebenenfalls neu zu beschreiben oder zu bemalen. Diese Systeme haben jedoch den Nachteil, daß sie häufig ein leichtflüchtiges organisches Lösungsmittel aufweisen, welches beim Verdunsten zu Umweltbelastungen führt. Bei Verwendung wässriger Systeme werden zwar die Umweltbelastungen vermieden, dabei muß jedoch eine verlängerte Trocknungszeit in Kauf genommen werden.It is known spelling or typing errors or incorrect ones possible representations with pigmented liquid systems to cover and, if necessary, new after drying to describe or paint. However, these systems have the disadvantage that they are often a volatile organic Have solvents that evaporate leads to environmental pollution. When using watery Systems are avoided while doing so however, an extended drying time must be accepted become.
Aus diesem Grunde sind mehrschichtige Übertragungsbänder entwickelt worden, bei denen eine auf einem Träger liegende pigmentierte Deckschicht mit einer Haftklebeschicht überzogen ist. Dadurch wird das mehrschichtige Korrekturmaterial mit seiner Haftklebeschicht über die zu korrigierende bzw. abzudeckende Stelle gelegt und Druck auf den oben liegenden Träger ausgeübt. Dadurch wird die Haftklebeschicht auf das Papier gedrückt und bleibt daran haften. Die Deckschicht löst sich dabei vom Träger, der üblicherweise als Folie ausgebildet ist ab, so daß er nun auf der gewünschten Papierstelle klebt und die darunterliegende Beschriftung abdeckt. Die DE-B-3 741 022 beschreibt ein mehrschichtiges flexibles Übertragungsband mit einer Trägerfolie, dabei wird das Abreißverhalten der Abdeckschicht durch die Zugabe von Cellulosederivaten verbessert, so daß die an den Kunststoffträger gebundene Abdeckschicht beim Auftragen scharf abreißt. Bei der Herstellung dieses Korrekturbandes werden jedoch organische Lösungs- und Dispergiermittel wie Isopropylalkohol und Toluol verwendet.For this reason, there are multilayer transmission bands have been developed in which a lying on a support pigmented top layer with a pressure sensitive adhesive layer is covered. This will make the multilayer correction material with its pressure sensitive adhesive layer over the one to be corrected or place to be covered and pressure on the exercised overhead straps. This will make the PSA layer pressed onto the paper and sticks to it. The cover layer detaches from the carrier, which is usually is designed as a film, so that it is now on the desired paper spot sticks and the underlying one Lettering covers. DE-B-3 741 022 describes a multilayer flexible transfer belt with one Carrier film, the tearing behavior of the cover layer improved by the addition of cellulose derivatives, so that the cover layer bound to the plastic carrier tears off sharply when applied. In the preparation of of this correction band, however, become organic Solvents and dispersants such as isopropyl alcohol and Toluene used.
Die DE-A-4 129 413 beschreibt die Herstellung eines mehrschichtigen Korrekturmaterials, das ohne Einsatz von organischen Lösungsmitteln und ohne die Mitverwendung von abrißfördernden Cellulosederivaten hergestellt werden kann. Dies wird durch einen besonderen Aufbau des die Abdeckschicht bildenden überzugsmittels und die Abstimmung mit der für die Haftung verantwortlichen Overcoat-Beschichtung erreicht. Dabei wird auf die getrocknete Abdeckschicht eine wässrige Overcoat-Beschichtung aufgetragen, die eine Polyethylenwachsdispersion, eine anionische Polyacrylatdispersion und gegebenenfalls einen Emulgator sowie weitere übliche Additive enthält.DE-A-4 129 413 describes the production of a multilayer correction material that without the use of organic solvents and without the use of tear-promoting cellulose derivatives are produced can. This is due to a special structure of the Cover layer forming coating agent and the vote with the overcoat coating responsible for the liability reached. It is on the dried An aqueous overcoat coating applied, which is a polyethylene wax dispersion, an anionic Polyacrylate dispersion and optionally one Contains emulsifier and other conventional additives.
Die Erfindung hat nun zum Ziel ein mehrschichtiges Korrekturmaterial, insbesondere in Form eines aufgerollten Bandes der eingangs geschilderten Art bereitzustellen, das ohne die Verwendung von organischen Lösungsmitteln, d. h. das allein in wässriger Lösung bzw. Suspension hergestellt werden kann. Ein weiteres Ziel der Erfindung ist, ein derartiges Übertragungs- bzw. Korrekturmittel bereitzustellen, das kein Abrißmittel als Additiv benötigt. Schließlich ist es noch ein Ziel der Erfindung, auf einen Overcoat zu verzichten, der eine Wachsdispersion enthält.The aim of the invention is now a multilayer correction material, especially in the form of a rolled up To provide tape of the type described above, the without the use of organic solvents, i.e. H. that is produced alone in aqueous solution or suspension can be. Another object of the invention is a to provide such transmission or correction means, that does not require a demolition agent as an additive. Finally, it is still an aim of the invention, on one To do without an overcoat that contains a wax dispersion.
Die zuvor genannten Ziele werden erfindungsgemäß mit einem Korrektur- und/oder Markierungsmittel erreicht, das einen auf einen Träger angeordneten ablösbaren, beschriftbaren Film aufweist, der mit einem Kleber überschichtet ist, dadurch gekennzeichnet, daß der beschriftbare Film bzw. Deckschicht ein filmbildendes, nicht sprödes Bindemittel und ein bei Raumtemperatur sprödes Bindemittel aufweist. Als spröde Bindemittel können auch solche Bindemittel eingesetzt werden, welche zunächst filmbildende Eigenschaften aufweisen, jedoch zusammen mit den weiteren Additiven, insbesondere mit Pigmenten eine spröde Masse bildet.According to the invention, the aforementioned goals are achieved with a Correction and / or marking means achieved that one removable, inscribable arranged on a carrier Film that is covered with an adhesive, characterized in that the writable film or Top layer is a film-forming, non-brittle binder and has a brittle binder at room temperature. Such binders can also be used as brittle binders are used, which initially have film-forming properties have, but together with the others Additives, especially with pigments a brittle mass forms.
Erfindungsgemäß hat es sich nämlich gezeigt, daß sich mit einem derart ausgebildeten Abdeckfilm sowohl gute Abrißeigenschaften erreichen lassen, und daß dabei auf die Verwendung organischer Lösungsmittel sowie eines Wachse enthaltenden Overcoats verzichtet werden kann.According to the invention it has been shown that with a cover film designed in this way has both good tear-off properties let achieve, and that in doing so on the Use of organic solvents and waxes containing overcoats can be dispensed with.
Filmbildende Bindemittel sind beispielsweise terpolymere Dispersionen auf der Basis von Vinylacetat und Acrylsäureestern, wie sie unter der Markenbezeichnung Macrovil 21 2 G von der Indulor Chemie GmbH, 49572 Ankum, Deutschland, vertrieben werden. Ein weiteres erfindungsgemäß zu verwendendes filmbildendes Bindemittel sind beispielsweise Copolymere auf der Basis von Acrylsäureestern mit Verwendung von Acrylnitril, wie sie unter der Bezeichnung Arconal 85 D erhältlich sind.Film-forming binders are, for example, terpolymers Dispersions based on vinyl acetate and Acrylic acid esters, such as those under the brand name Macrovil 21 2 G from Indulor Chemie GmbH, 49572 Ankum, Germany. Another one Film-forming binder to be used according to the invention are, for example, copolymers based on Acrylic acid esters using acrylonitrile as they do are available under the name Arconal 85 D.
Spröde wirkende Bindemittel sind beispielsweise Acrylpolymere, insbesondere solche in Ammoniak, wie sie beispielsweise unter der Bezeichnung Carboset 537 von B.F. Goodrich, Cleveland, Ohio, als 35%-ige Feststoffdispersion in ammoniakalischem Wasser vertrieben werden. Ein weiteres sprödes Bindemittel sind carboxylgruppenhaltige Copolymere auf Basis von Acrylsäureestern, wie sie beispielsweise unter der Markenbezeichnung Acronal V 205 kommerziell erhältlich sind. Mit dem erfindungsgemäßen Deckfilm lassen sich sowohl Korrektur- als auch Markierungsmittel, sogenannte Transliner, herstellen. Bei der Herstellung von Korrekturfilmen enthält die Filmschicht abdeckende Pigmente, wie beispielsweise Titandioxyd und Füllmittel. Bei den Markierungsmitteln oder Translinern ist anstelle eines abdeckenden Pigmentes ein fluoreszierender Farbstoff, wie beispielsweise Aminotriazinformaldehyd-Cokondensate mit organischen Farbstoffen enthalten.Brittle-acting binders are, for example Acrylic polymers, especially those in ammonia, as they for example under the name Carboset 537 from B.F. Goodrich, Cleveland, Ohio, as a 35% solids dispersion are distributed in ammoniacal water. Another one brittle binders are copolymers containing carboxyl groups based on acrylic acid esters, such as commercial under the brand name Acronal V 205 are available. Leave with the cover film of the invention both correction and marking agents, so-called Transliner. In the manufacture of Correction films contain pigments covering the film layer, such as titanium dioxide and fillers. At the marker or transliner is instead of one covering pigment a fluorescent dye, such as for example, aminotriazine formaldehyde cocondensates contain organic dyes.
Zur Herstellung der erfindungsgemäßen Korrektur- und Markierungsmittel wird eine wässrige Suspension aus einem sprödem und einem filmbildenden, nicht spröden Bindemittel zusammen mit einem Pigment und/oder Farbstoff und gegebenenfalls Fluornetzmitteln wie FC 170 C und Entschäumern, wie beispielsweise Acitan 281 beispielsweise mit hydrophoben Kieselsäuren, synthetischen Copolymeren und nicht-ionischen Emulgatoren zugesetzt. In besonderen Fällen hat es sich als zweckmäßig erwiesen, auch pH-Stabilisatoren, wie beispielsweise 2-Amina-2-Methyl-1-Propionat zusammen mit Füllstoffen und oberflächenaktiven Mitteln und gegebenenfalls mit Verdikkungsmitteln zuzusetzen.To produce the correction and Marking agent is an aqueous suspension from a brittle and a film-forming, non-brittle binder together with a pigment and / or dye and optionally Fluorine wetting agents such as FC 170 C and defoamers, such as Acitan 281, for example, with hydrophobic Silicas, synthetic copolymers and added non-ionic emulsifiers. In particular Cases, it has proven to be useful, including pH stabilizers, such as 2-amina-2-methyl-1-propionate along with fillers and surfactants Agents and, if necessary, with thickeners to add.
