Description
Für das Offsetdruckverfahren ist die gegenseitige Abstoßung von fetter Farbe und Wasser sehr wichtig. In der Regel läßt man während des Druckvorganges sowohl fette Farbe als auch Wasser an die Offsetdruckplatte herantreten, wobei das Wasser die Aufgabe hat, die nicht druckenden Teile der Druckplatte vor der Farbannahme zu schützen. Häufig wird das Wasser von der Druckfarbe verdrängt, und es tritt Hydrophobierung der Druckplatte auch an den Stellen ein, die fette Farbe nicht annehmen sollen.The mutual repulsion of fat ink and water is very important for the offset printing process. As a rule, both greasy ink and water are left on the offset printing plate during the printing process Approach, the task of the water being the non-printing parts of the printing plate to protect against ink acceptance. Often the water is displaced by the printing ink and it occurs Make the printing plate water-repellent even in the areas that should not take on the greasy color.
Um solcher unerwünschten Hydrophobierung vorzubeugen, hat man schon die Verwendung solcher Feuchtmittel (Feuchtwasser) vorgeschlagen, die nicht nur aus Wasser bestehen, sondern noch Zusatzstoffe enthalten. Auch diese arbeiten nicht in allen Fällen befriedigend. So verursachen Metallsalze im Feuchtwasser bei längerem Kontakt mit der Druckplatte auf dieser unerwünschte Kristallbildungen. Wenn man wäßrige Lösungen von mehrwertigen Alkoholen gebrauchen will, müssen relativ konzentrierte Lösungen verwendet werden, die von der Raumtemperatur und dem Feuchtigkeitsgehalt der Luft beträchtlich abhängig sind und klebrige Drucke ergeben. Beim Gebrauch von Kolloiden, wie lösliche Stärke, Gummiarabikum und andere pflanzliche Gummis, als Feuchtmittelzusatz wirkt sich schädlich aus, daß sie ausgezeichnete Nährböden für Pilze und Bakterien sind. Bei den Druckplatten, die aus den neuerdings in Gebrauch gekommenen vorsensibilisierten Druckfolien hergestellt sind, greifen die bisher verwendeten Feuchtmittel häufig auch die Bildstellen an, oder sie vermögen nicht zu verhindern, daß nach Maschinenstillstand die Druckplatten an den bildfreien Stellen tonen. Hochdisperses Siliciumdioxyd enthaltende Feuchtmittel werden bei langer Lagerung inhomogen, weil sich die Siliciumdioxydteilchen absetzen.In order to prevent such undesirable hydrophobization, one already has the use of such Fountain solution (fountain solution) proposed that consist not only of water, but also additives contain. Even these do not work satisfactorily in all cases. So cause metal salts in the fountain solution in the event of prolonged contact with the printing plate, undesirable crystal formations on it. If Wants to use aqueous solutions of polyhydric alcohols must be relatively concentrated solutions which depends considerably on the room temperature and the moisture content of the air are and give sticky prints. When using colloids such as soluble starch, gum arabic and other vegetable gums, as a dampening solution additive, has a detrimental effect that makes them excellent Are breeding grounds for fungi and bacteria. In the case of the printing plates from the ones that have recently come into use presensitized printing foils are produced, the dampening solutions used up to now often take effect also the image areas, or they are unable to prevent the Toning the printing plates in the non-image areas. Fountain solutions containing highly dispersed silicon dioxide become inhomogeneous after long storage because the silicon dioxide particles settle out.
Solche Offsetdruckfeuchtmittel werden auch als Tonschutzmittel bezeichnet.Such offset printing dampening agents are also referred to as sound protection agents.
Gegenstand der vorliegenden Erfindung sind Feucht- und Reinigungsmittel für das Offsetdruckverfahren, die durch einen Gehalt an monomerer und/ oder polymerer Vinylphosphorsäure gekennzeichnet sind. Bei ihrer Verwendung erhält man ausgezeichnete Drucke.The present invention relates to dampening and cleaning agents for offset printing, characterized by a content of monomeric and / or polymeric vinyl phosphoric acid are. Excellent prints are obtained when they are used.
Es hat sich gezeigt, daß bei Anwesenheit von monomerer und/oder polymerer Vinylphosphonsäure im
Feuchtwasser beim Offsetdruckverfahren die oben angegebenen Nachteile nicht auftreten. Ein sehr großer,
technisch bedeutsamer Vorteil liegt darin, daß der Gebrauch des erfindungsgemäßen Feuchtmittels das
Gummiarabikum der Druckplatte bei Maschinenstillstand überflüssig macht, da die Phosphonsäuren die
Feucht- und Reinigungsmittel
für das OffsetdruckverfahrenIt has been shown that when monomeric and / or polymeric vinylphosphonic acid is present in the fountain solution in the offset printing process, the above-mentioned disadvantages do not occur. A very great, technically significant advantage is that the use of the dampening solution according to the invention makes the gum arabic of the printing plate superfluous when the machine is idle, since the phosphonic acids are the dampening and cleaning agents
for the offset printing process

Metalloberfläche des Druckträgers durch Bildung einer Deckschicht vor dem Angriff des Luftsauerstoffs schützen. Vorteilhaft ist bei der erfindungsgemäßen Verwendung als Feuchtwasser auch der minimale Verbrauch. Dadurch kann auch der Verbrauch an Druckfarbe entsprechend reduziert werden, und die Drucke fallen gut farbsatt an.Metal surface of the print carrier by forming a cover layer before attack by atmospheric oxygen protection. In the case of the use according to the invention as dampening water, the minimum is also advantageous Consumption. As a result, the consumption of printing ink can be reduced accordingly, and the Prints are rich in color.
Vinylphosphonsäure und ihre Polymeren hydrophilieren Oberflächen von Metallen, besonders von Aluminium und Zink, die als Druckträger im Offsetdruck Verwendung finden, wesentlich stärker, als es z. B. die viel verwendete Orthophosphorsäure vermag. Diese Hydrophilierung ist zugleich eine Reinigung der Metalloberflächen von etwa vorhandenen öligen und fetten Verunreinigungen. Bisher bekannte Reinigungsmittel sind Dispersionen und enthalten mehrere inhomogene Stoffe, wie es beispielsweise bei der im USA.-Patent 2 780 168 beschriebenen Dispersion der Fall ist, die als Reinigungsmittel für befettete Druckplatten dient und in der wäßrigen Phase einwertige und mehrwertige Alkohole und eine kolloidale Dispersion von Kieselsäure enthält und in deren nichtwäßriger Phase vorzugsweise Petroläther enthalten sind.Vinylphosphonic acid and its polymers hydrophilize surfaces of metals, especially of Aluminum and zinc, which are used as printing carriers in offset printing, are much stronger than it is z. B. is capable of the much used orthophosphoric acid. This hydrophilization is also a cleaning of the Metal surfaces of any oily and greasy contaminants that may be present. Previously known cleaning agents are dispersions and contain several inhomogeneous substances, as is the case with the im U.S. Patent 2,780,168 is the case, as a cleaning agent for greased printing plates serves and monohydric and polyhydric alcohols and a colloidal dispersion in the aqueous phase of silica and preferably contain petroleum ether in its non-aqueous phase are.
Die Herstellung von Vinylphosphonsäure und zahlreicher ihrer Derivate ist in der Patentliteratur beschrieben. The preparation of vinylphosphonic acid and many of its derivatives is described in the patent literature.
Man erhält das erfindungsgemäße Feuchtmittel auf einfache Weise durch Auflösen von Vinylphosphonsäure oder Polyvinyiphüsphonsäure oder Mischungen dieser beiden Substanzen in Wasser. Die Auflösung tritt leicht ein. Feuchtwasser mit sehr geringen Konzentrationen an Phosphonsäure, beispielsweise von 0,0001 %. ergeben schon gute Resultate im Offsetdruck. Für die Praxis empfiehlt es sich jedoch im allgemeinen, Feuchtwasser zu verwenden, bei denen dieThe dampening solution according to the invention is obtained in a simple manner by dissolving vinylphosphonic acid or polyvinyl phosphonic acid or mixtures of these two substances in water. The resolution occurs easily. Fountain solution with very low concentrations of phosphonic acid, for example from 0.0001%. already give good results in offset printing. In practice, however, it is generally advisable to use fountain solutions for which the

Konzentration an Vinylphosphonsäure oder PoIyvinylphosphonsäure 0,001 bis 0,1 %> in Wasser beträgt. Concentration of vinyl phosphonic acid or polyvinyl phosphonic acid 0.001 to 0.1%> in water.
Für die Reinigung der metallischen Druckträger von befetteten und öligen Stellen verwendet man vorteilhaft höhere Konzentrationen, beispielsweise von 0,1 bis lO°/o Vinylphosphonsäure und/oder PoIyvinylphosphonsäure in Wasser. Es kann vorteilhaft sein, dem erfindungsgemäßen Feuchtwasser weitere Zusätze hinzuzufügen, darunter auch solche, deren Verwendung im Feuchtwasser bereits bekannt ist. Beispiele solcher weiteren wasserlöslichen bzw. mit Wasser mischbaren Zusatzstoffe sind Ammoniumphosphat, citronensäure Salze, Glycerin und andere Alkohole, Polyglykole, Dextrine, Alginate, Carboxymethylcellulosen und pflanzliche Gummis, von denen man jeden für sich oder mehrere zusammen dem erfindungsgemäßen Feuchtwasser zusetzen kann.For cleaning the metallic print media from greased and oily areas, it is advantageous to use higher concentrations, for example from 0.1 to 10% vinylphosphonic acid and / or polyvinylphosphonic acid in water. It can be advantageous to add further additives to the fountain solution according to the invention, including those whose use in the fountain solution is already known. Examples of such other water-soluble or water-miscible additives are ammonium phosphate, citric acid salts, glycerine and other alcohols, polyglycols, dextrins, alginates, carboxymethyl celluloses and vegetable gums, each of which can be added individually or several together to the fountain solution according to the invention.
Zur Anfärbung der an sich farblosen Lösungen der Vinylphosphonsäure oder Polyvinylphosphonsäure können ihnen geringe Mengen von Farbstoffen zugefügt werden.For coloring the inherently colorless solutions of vinylphosphonic acid or polyvinylphosphonic acid small amounts of dyes can be added to them.
