Abstract

Process for drying printing ink on a printing substrate comprises, irradiating the printing substrate with infrared radiation, and inserting an infrared absorber (preferably hexarylene) to absorb the infrared radiation.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Trocknen von Druckfarbe auf einem Bedruckstoff mit den Merkmalen des Oberbegriffs von Anspruch 1.The The present invention relates to a process for drying ink on a substrate having the features of the preamble of claim 1.

Es ist aus dem Stand der Technik bereits bekannt, Druckfarben auf Bedruckstoffen zu trocknen, z.B. durch den Einsatz von Infrarotstrahlung. Hierzu wird zunächst die Druckfarbe auf den Bedruckstoff aufgebracht bzw. verdruckt. Dieses Verdrucken der Druckfarbe kann in einer Druckmaschine erfolgen. Anschließend wird der Bedruckstoff mit Infrarotstrahlung, insbesondere NIR-Strahlung bestrahlt und die Druckfarbe trocknet und/oder härtet aus. Es ist weiterhin bekannt, die Druckfarben mit Additiven zu versehen, welche als Absorber für die Trocknungsstrahlung dienen.It is already known from the prior art, printing inks on substrates to dry, e.g. through the use of infrared radiation. For this will be first the printing ink applied or printed on the substrate. This printing of the ink can be done in a printing press. Subsequently is the substrate with infrared radiation, in particular NIR radiation irradiated and the ink dries and / or hardens. It is still It is known to provide the printing inks with additives which serve as absorbers for the drying radiation serve.

Die DE 103 16 472 A1 offenbart z.B. ein Verfahren zum Trocknen einer Druckfarbe auf einem Bedruckstoff, wobei ein Behandlungsmittel, welches eine Beschleunigung der Trocknung der Druckfarbe bewirkt, als Beschichtung oder als Grundierung aufgebracht und der Bedruckstoff bzw. die Druckfarbe durch Einwirkung von Strahlung getrocknet wird. Das Behandlungsmittel kann einen Infrarotabsorber umfassen, dessen Absorptionswellenlänge im Wesentlichen resonant zur Wellenlänge zur Strahlung ist. Das Dokument verweist in Absatz [0020] – ohne im Folgenden näher darauf einzugehen – hinsichtlich beispielhafter Absorber auf eine Dissertation zum Thema „Monomere und polymere Rylenfarbstoffe als funktionelle Materialien".The DE 103 16 472 A1 discloses, for example, a method for drying a printing ink on a printing substrate, wherein a treatment agent which causes an acceleration of the drying of the ink applied as a coating or as a primer and the printing material or the ink is dried by the action of radiation. The treating agent may comprise an infrared absorber whose absorption wavelength is substantially resonant with the wavelength to the radiation. The document refers in paragraph [0020] - without going into more detail below - with regard to exemplary absorbers to a dissertation on "monomers and polymeric rylene dyes as functional materials".

In der DE 10 2005 032 583 A1 wird in Absatz [0002] die Verwendung von Rylenderivaten zur Einfärbung von hochmolekularen organischen und anorganischen Materialien (vgl. hierzu Absatz [0120]: Einfärbung von Lacken und Druckfarben) und – ohne im Folgenden näher darauf einzugehen – als Infrarotabsorber für das Wärmemanagement beschrieben (vgl. hierzu Absatz [0124]: Verweis auf die Dokumente WO-A-02/77081 und 04/05427, die sich mit dem Wärmemanagement im Bereich „Wärmeisolationsbeschichtung" beschäftigen]). In Absatz [0054] werden beispielhaft Pentarylen- und Hexarylenderivate genannt und in Absatz [0122] wird darauf hingewiesen, dass gewisse Rylenderivate aufgrund ihres Absorptionsvermögens im nahinfraroten Bereich von Interesse sind. Ein Zusammenhang zwischen den Rylenen und dem Trocknen von Druckfarben ist jedoch nicht offenbart.In the DE 10 2005 032 583 A1 paragraph [0002] describes the use of rylene derivatives for coloring high-molecular-weight organic and inorganic materials (cf., paragraph [0120]: coloring of paints and printing inks) and, without going into more detail below, as infrared absorbers for thermal management (cf. for this paragraph [0124]: reference to the documents WO-A-02/77081 and 04/05427, which deal with the thermal management in the field of "thermal insulation coating"].) In paragraph [0054] are exemplified Pentarylen- and Hexarylenderivate and It is noted in paragraph [0122] that certain rylene derivatives are of interest because of their near-infrared absorbency, but there is no disclosure of an association between the rylenes and the drying of inks.

Aus der DE 10 2005 018 241 A1 sind ebenfalls Hexarylene bekannt. In Absatz [0237] ist beschrieben, dass sie sich zum Einfärben von hochmolekularen organischen und anorganischen Materialien, z.B. von Lacken und Druckfarben eignen. Die DE 10 2004 057 585 A1 nennt Rylene bis zu den Quaterrylenen, welche im Nahinfrarot stark absorbieren (vgl. hierzu Absatz [0003]) und ebenfalls zum Einfärben und für das Wärmemanagement verwendet werden können (vgl. hierzu Absatz [0046]). Ein Zusammenhang zwischen den offenbarten Rylenen und dem Trocknen von Druckfarben ist jedoch nicht offenbartFrom the DE 10 2005 018 241 A1 Hexarylenes are also known. Paragraph [0237] describes that they are suitable for coloring high molecular weight organic and inorganic materials, for example paints and printing inks. The DE 10 2004 057 585 A1 calls rylenes up to the quaterrylenes, which absorb strongly in the near infrared (cf paragraph [0003]) and can also be used for coloring and for thermal management (see paragraph [0046]). However, a connection between the disclosed Rylenen and the drying of printing inks is not disclosed

Behandlungsmittel, wie z.B. die in der DE 103 16 472 A1 beschriebenen, welche als Infrarotabsorber Druckfarben beigegeben werden, sollen den mit dem Auge wahrnehmbaren Farbeindruck der Druckfarbe jedoch wenig oder nicht beeinflussen bzw. verändern, d.h. wenig oder keine Absorption im sichtbaren Spektralbereich aufweisen. Ein „Einfärben", wie in den Dokumenten DE 10 2005 032 583 A1 , DE 10 2005 018 241 A1 und DE 10 2004 057 585 A1 beschrieben, ist also gerade nicht erwünscht. Auch die bereits als Additive für Druckfarben bekannten und entsprechend eingesetzten Cyaninabsorber weisen ein unvorteilhaft breites Absorptionsspektrum im sichtbaren Bereich auf. Es besteht folglich ein Interesse an verbesserten Infrarotabsorbern für den Einsatz beim Trocknen von Druckfarben. Da Rylene einen sehr hohen Extinktionskoeffizienten bezüglich der zur Trocknung eingestrahlten Infrarotstrahlung aufweisen können und verglichen mit den Cyaninen in der Regel eine schmale Absorptionsbande aufweisen, bieten die Rylene eine untersuchenswerte Alternative zu den Cyaninen.Treatment agents, such as those in the DE 103 16 472 A1 described, which are added as infrared absorber printing inks, but should little or no influence or change the perceptible with the eye color impression of the ink, ie have little or no absorption in the visible spectral range. A "coloring", as in the documents DE 10 2005 032 583 A1 . DE 10 2005 018 241 A1 and DE 10 2004 057 585 A1 described, so it is just not wanted. The cyanine absorbers already known and used as additives for printing inks also have an unfavorably broad absorption spectrum in the visible range. There is thus an interest in improved infrared absorbers for use in drying inks. Since rylenes can have a very high extinction coefficient with respect to the infrared radiation irradiated for drying and, as a rule, have a narrow absorption band compared with the cyanines, the rylenes offer an alternative to the cyanines which is worth examining.

Es ist eine Aufgabe der vorliegenden Erfindung, ein gegenüber dem Stand der Technik verbessertes Verfahren zu schaffen, welches die Trocknung von Druckfarben und Lacken unter Einsatz von Infrarotabsorbern ermöglicht.It is an object of the present invention, one over the Prior art to provide improved method, which the Drying of printing inks and varnishes using infrared absorbers allows.

Es ist eine weitere oder alternative Aufgabe der vorliegenden Erfindung, ein gegenüber dem Stand der Technik verbessertes Verfahren zu schaffen, welches die Trocknung von Druckfarben und Lacken unter Einsatz von Infrarotabsorbern ermöglicht, ohne dass durch den Einsatz des Infrarotabsorbers der wahrnehmbare Farbeindruck der Druckfarbe oder des Lacks beeinflusst bzw. verändert wird.It is another or alternative object of the present invention, one opposite to provide the prior art improved method which the drying of printing inks and varnishes using infrared absorbers allows without the use of the infrared absorber of the perceivable color impression the printing ink or varnish is influenced or changed.
