Definitions
- the present invention relates to aqueous recording liquids containing
- a number of requirements are imposed on recording liquids and in particular inks used in the ink jet process (ink jet printing processes such as thermal ink jet, piezo ink jet, continuous ink jet, valve jet, transfer printing process): they must have suitable viscosity and Surface tension, they must be stable in storage, that is, they should not coagulate or locate, and they must not clog the printer nozzle, which can be problematic, in particular, when the inks contain dispersed, ie undissolved, colorant particles.
- the requirements for the storage stability of these recording liquids and in particular inks also include that dispersed colorant particles do not settle.
- the inks In the case of the continuous ink jet, the inks must also be stable against the addition of conductive salts and show no tendency to flocculate when the ion content is increased.
- the prints obtained must meet the color requirements, i.e. show high brilliance and depth of color, and good fastness properties, e.g. Rub fastness, light fastness, water fastness and wet rub fastness, if necessary after post-treatment such as fixation, and have good drying behavior.
- the inks it is necessary for the inks to dry on the substrate as quickly as possible so that images or lettering to be printed do not run and for example the ink droplets of different colors do not mix.
- the state of the inks known to date, also known as the definition of the prints, is still to be improved.
- EP 1 153992 describes pigmented inks, the pigment particles being coated with a resin and the resin having an anionic group and the ink being 0.1 to 5% by weight of an acetylene glycol surfactant and / or a polysiloxane of the formula A1 in addition to the coated pigment
- j and k each stand for 1 or more, the radicals R are identical or different and stand for CrC 6 alkyl, and EOPO-H stands for at least one ethylene oxide unit or at least one propylene oxide unit or at least one polyalkylene oxide unit in which the ethylene oxide and propylene oxide units can be strung together in statistical or block form.
- EP 1 234 859 claims a pigmented ink which contains at least one compound of the general formula A2
- No. 6,241,811 claims an ink formulation which contains an optionally alkoxylated acetylene glycol compound.
- EP 1 333048 discloses ink formulations with 20 to 60% solids, each containing a specially substituted acetylenediol.
- EP 1 295916 discloses inks for the ink jet process which contain a completely polymer-coated pigment or a completely polymer-coated dye, furthermore water and at least one special compound selected from acetylene glycol compounds, acetylene alcohols, glycol ethers or 1, 2-alkylene. Fully polymer-coated pigments or dyes are disclosed in accordance with the disclosure of
- EP 1 295916 for example, is made in such a way that the required polymer is prepared in the presence of a pigment or dye to be completely coated.
- the use of completely polymer-coated pigment is essential according to EP 1 295916, because otherwise satisfactory images cannot be achieved (p. 12, line 54 to p. 13, line 4).
- the object was therefore to provide recording liquids and in particular inks for the ink jet process which do not have the disadvantages mentioned above.
- a further object was to provide a process for the production of improved recording liquids and in particular inks for the ink jet process. Furthermore, there was the task of providing printed substrates.
- inks and inks are also used for the ink jet process for recording liquids.

Description
Beschreibungdescription
Die vorliegende Erfindung betrifft wässrige Aufzeichnungsflüssigkeiten, enthaltendThe present invention relates to aqueous recording liquids containing
(a) mindestens einen Dispersfarbstoff,(a) at least one disperse dye,
(b) mindestens zwei Netzmittel.(b) at least two wetting agents.
An Aufzeichnungsflüssigkeiten und insbesondere Tinten, die beim Ink-Jet-Verfahren (Tintenstrahldruckverfahren wie Thermal Ink Jet, Piezo Ink Jet, Continuous Ink Jet, Valve Jet, Transferdruckverfahren) eingesetzt werden, werden eine Reihe von Anforderungen gestellt: Sie müssen zum Drucken geeignete Viskosität und Oberflächenspannung aufweisen, sie müssen lagerstabil sein, d.h., sie sollen nicht koagulieren oder f lokulieren, und sie dürfen nicht zur Verstopfung der Druckerdüse führen, was insbesondere bei dispergierten, also nicht gelöste Farbmittelteilchen enthaltenden Tinten problematisch sein kann. Die Anforderungen an die Lagerstabilität dieser Aufzeichnungsflüssigkeiten und insbesondere Tinten beinhaltet zusätzlich, dass sich dispergier- te Farbmittelteilchen nicht absetzen. Weiterhin müssen die Tinten im Falle des Conti- nuous Ink Jet stabil gegen den Zusatz von Leitsalzen sein und bei Erhöhung des lo- nengehaltes keine Tendenz zum Ausflocken zeigen. Außerdem müssen die erhaltenen Drucke den koloristischen Anforderungen genügen, d.h. hohe Brillanz und Farbtiefe zeigen, und gute Echtheiten, z.B. Reibechtheit, Lichtechtheit, Wasserechtheit und Nassreibechtheit, gegebenenfalls nach Nachbehandlung wie beispielsweise Fixierung, und gutes Trocknungsverhalten aufweisen.A number of requirements are imposed on recording liquids and in particular inks used in the ink jet process (ink jet printing processes such as thermal ink jet, piezo ink jet, continuous ink jet, valve jet, transfer printing process): they must have suitable viscosity and Surface tension, they must be stable in storage, that is, they should not coagulate or locate, and they must not clog the printer nozzle, which can be problematic, in particular, when the inks contain dispersed, ie undissolved, colorant particles. The requirements for the storage stability of these recording liquids and in particular inks also include that dispersed colorant particles do not settle. In the case of the continuous ink jet, the inks must also be stable against the addition of conductive salts and show no tendency to flocculate when the ion content is increased. In addition, the prints obtained must meet the color requirements, i.e. show high brilliance and depth of color, and good fastness properties, e.g. Rub fastness, light fastness, water fastness and wet rub fastness, if necessary after post-treatment such as fixation, and have good drying behavior.
Außerdem ist es erforderlich, dass die Tinten auf dem Substrat möglichst schnell trocknen, damit zu druckende Bilder oder Schriftzüge nicht verlaufen und sich beispielsweise die Tintentröpfchen verschiedener Farbe nicht vermischen. Dabei ist es zur Herstellung von gestochen scharfen Drucken erforderlich, dass man nicht nur die Trocknungszeit der Drucke minimiert, sondern dass auch während der Zeit, in der die Tintentröpfchen auf dem zu bedruckenden Substrat stehen, die Tintentröpfchen nicht verlaufen. Diese Fähigkeit der Tinte wird auch als Stand bezeichnet. Der Stand der bisher bekannten Tinten, auch als Definition der Drucke bezeichnet, ist noch zu verbessern.In addition, it is necessary for the inks to dry on the substrate as quickly as possible so that images or lettering to be printed do not run and for example the ink droplets of different colors do not mix. In order to produce razor-sharp prints, it is necessary not only to minimize the drying time of the prints, but also not to bleed during the time that the ink droplets are on the substrate to be printed. This ability of the ink is also called stand. The state of the inks known to date, also known as the definition of the prints, is still to be improved.

Es zeigt sich jedoch, dass die drucktechnischen Eigenschaften der aus dem Stand der Technik bekannten Tinten noch zu verbessern sind. Beispielsweise neigen einige der aus dem Stand der Technik bekannten Tinten noch stark zum Schäumen.EP 1 295916, for example, is made in such a way that the required polymer is prepared in the presence of a pigment or dye to be completely coated. The use of completely polymer-coated pigment is essential according to EP 1 295916, because otherwise satisfactory images cannot be achieved (p. 12, line 54 to p. 13, line 4). However, it has been shown that the printing properties of the inks known from the prior art can still be improved. For example, some of the inks known from the prior art still have a strong tendency to foam.

Abschließend kann man jeweils mit einer Filtriervorrichtung mit Feinabtrennung im Bereich von 1 bis 0,5 μm filtrieren. So kann man erfindungsgemäße Aufzeichnungsflüssigkeiten und insbesondere erfindungsgemäße Ink-Jet-Tinten erhalten.Finally, you can filter with a filter device with fine separation in the range of 1 to 0.5 μm. Thus, recording liquids according to the invention and in particular ink jet inks according to the invention can be obtained.
Erfindungsgemäße Aufzeichnungsflüssigkeiten kann man direkt als oder zur Herstel- lung von Tinten, beispielsweise für das Ink-Jet-Verfahren verwenden. Insbesondere kann man erfindungsgemäße Aufzeichnungsflüssigkeiten direkt als oder zur Herstellung von Tinten für das Ink-Jet-Verfahren verwenden. Andere geeignete Tinten sind beispielsweise Tinten für Federhalter. Ein weiterer Gegenstand der vorliegenden Erfindung ist daher die Verwendung erfindungsgemäßer Aufzeichnungsflüssigkeiten als Tinten für das Ink-Jet-Verfahren. Ein weiterer Gegenstand der vorliegenden Erfindung ist ein Verfahren zum Bedrucken von Substraten unter Verwendung von erfindungsgemäßen Aufzeichnungsflüssigkeiten.
Wünscht man erfindungsgemäße Aufzeichnungsflüssigkeiten zur Herstellung von Tinten zu verwenden, so arbeitet man in der Regel so weiter, dass man erfindungsgemäße Aufzeichnungsflüssigkeiten verdünnt, beispielsweise mit Wasser, welches ein oder mehrere weitere der oben genannten Hilfsstoffe (e) enthalten kann.

In particular, recording liquids according to the invention can be used directly as or for the production of inks for the ink jet process. Other suitable inks are, for example, inks for pen holders. Another object of the present invention is therefore the use of recording liquids according to the invention as inks for the ink jet process. Another object of the present invention is a method for printing substrates using recording liquids according to the invention.

Ein weiterer Aspekt der vorliegenden Erfindung ist ein Verfahren zum Bedrucken von Substraten, die beispielsweise flächig oder dreidimensional sein können, nach dem Ink-Jet-Verfahren unter Verwendung erfindungsgemäßer Aufzeichnungsflüssigkeiten oder erfindungsgemäßer Tinten. Dazu druckt man erfindungsgemäße Aufzeichnungsflüssigkeiten bzw.

Beim Ink-Jet-Verfahren werden Tinten in kleinen Tröpfchen direkt auf das Substrat gesprüht. Man unterscheidet dabei ein kontinuierliches Verfahren, bei dem die Tinte gleichmäßig durch eine Düse gepresst und durch ein elektrisches Feld, abhängig vom zu druckenden Muster, auf das Substrat gelenkt wird, und ein unterbrochenes Tintenstrahl- oder "Drop-on-Demand"-Verfahren, bei dem der Tintenausstoß nur dort erfolgt, wo ein farbiger Punkt gesetzt werden soll. Bei dem letztgenannten Verfahren wird entweder über einen piezoelektrischen Kristall oder eine beheizte Kanüle (Bubble- oder Thermo-Jet-Verfahren) Druck auf das Tintensystem ausgeübt und so ein Tintentropfen herausgeschleudert. Solche Verfahrensweisen sind in Text. Chem. Color, Band 19 (8), Seiten 23 bis 29, 1987, und Band 21 (6), Seiten 27 bis 32, 1989, beschrieben.In the ink jet process, inks are sprayed directly onto the substrate in small droplets. A distinction is made between a continuous process in which the ink is pressed evenly through a nozzle and directed onto the substrate by an electric field, depending on the pattern to be printed, and an interrupted ink-jet or "drop-on-demand" process, where the ink is only ejected where a colored dot is to be set. In the latter method, pressure is exerted on the ink system either by means of a piezoelectric crystal or a heated cannula (bubble or thermo-jet method) and an ink drop is thus ejected. Such procedures are in text. Chem. Color, volume 19 (8), pages 23 to 29, 1987, and volume 21 (6), pages 27 to 32, 1989.
