Effect on glass bottles or packaging material of various types, or on objects such as book spines, leather, plastic material.
- the invention goes beyond this prior art. It is the object of the invention to use pearlescent pigments of this type directly instead of the bronzes based on heavy metals, such as Cu, which have hitherto been used to achieve gloss effects.
- the blockage should be removed by resilient metal strips (d) on the sloping longitudinal wall.
- the design of this bronze container is different, as shown in Figure 1.
- the front longitudinal wall is steep and the wall on which the sheet metal strips are located is formed obliquely.
- the front wall of the bronze box is inclined and the longitudinal wall on the outlet side is vertical.
- the flow angle according to this prior art is greater than 45 °. With a flow angle of 45 °, practically no storage volume of the specifically light bronze from pearlescent pigments can form.

- This device has numerous, independently movable plates which are intended to regulate the outlet of the bronze particles which are free-flowing.
- the flow angle is also greater than 45 °.
- Calcined rutile pigments are proposed as the base pigments.
- the Ti0 2 layer is small; this should amount to 50-500 mg Ti0 2 on mica flakes with a diameter of 5-200 microns and a thickness of 0.1-5 microns.
- a thin layer of a poorly soluble Cr-III compound is applied to the coated mica pigment and converted into Cr 2 0 3 by annealing.

- a sample is taken by immersing it in the bronzing compound, which practically covers the curved surface as a heap.
- the non-flowable state is defined by the fact that the bronzing compound does not run off the horizontally held round surface.
- Such copper bronzes have, for example, a copper content of 60 to 85% by weight. It can be seen that brushed copper bronze flows slowly and incompletely. This has changed not only in its original gloss effect in the direction of a matt, irregular gloss effect and in the color strength, but also in its structure, in particular due to agglomeration of the primary particles.
- the process of the invention means the technical measure of "bronzing" not only the application of bronzes according to the prior art, but also figuratively the application of the pearlescent pigments without Cu content and with only a low Cr content.
- Figures 1 and 2 explain the operation according to the method of the invention.
- Figure 1 shows the design of the bronze box (2) over the applicator roller (1) in cross section.

Description
Gegenstand der Erfindung ist ein Verfahren zum Bronzieren von mit Unterdruckfarbe behandelter Farbdrucke unter Verwendung von nicht fliessfähigen Perlglanzpigmenten.The invention relates to a method for bronzing color prints treated with negative pressure ink using non-flowable pearlescent pigments.
Durch die exponential zunehmende Weltbevölkerung wird der Bedarf an Versorgungsgütern ständig grösser. Es fallen dadurch immer grössere Mengen an Abfallstoffen an, die zur Verringerung der Umweltbelastung beseitigt werden müssen.Due to the exponentially increasing world population, the need for supplies is constantly increasing. As a result, ever larger amounts of waste material accumulate, which must be removed to reduce the environmental impact.
Eine solche Belastung der Umwelt entsteht auch durch Schwermetalle. Dies ist insbesondere dann der Fall, wenn Reinigungs- und Spülwässer einen Grenzwert von 2 mg/I Cu überschreiten. Dieser Wert kann durch Verwendung von schwermetall-haltigen Bronzen aus etikettierten Flaschen überschritten werden.Such a pollution of the environment is also caused by heavy metals. This is particularly the case when cleaning and rinsing water exceed a limit of 2 mg / I Cu. This value can be exceeded by using bronzes containing heavy metals from labeled bottles.
Es weisen beispielsweise Etiketten von Weinflaschen Cu-Gehalte bis 16,5 mg/Etikette auf. Solche Gehalte gibt Trogus und Rasenberger in "Der Deutsche Weinbau", 3, 1983, Seite 112 an. Diese Cu-Gehalte gelangen über Reinigungs- und Spülwässer von recyclisierten Flaschen in Kläranlagen und damit in kommunale Klärschlämme.For example, labels on wine bottles have Cu contents of up to 16.5 mg / label. Such contents are stated by Trogus and Rasenberger in "Der Deutsche Weinbau", 3, 1983, page 112. These Cu contents reach cleaning and rinsing water from recycled bottles in sewage treatment plants and thus in municipal sewage sludge.
Die Beseitigung der Schwermetalle wie Cu, durch Aufbereitung solcher Abwässer ist aufwendig und unwirtschaftlich.The removal of heavy metals such as Cu by treating such waste water is complex and uneconomical.
Aus der DE-A-3 224 558 ist die Verwendung von Perlglanzpigmente in der Drucktechnik beschrieben.DE-A-3 224 558 describes the use of pearlescent pigments in printing technology.
Die Erfindung nach DE-A-3 224 558 betrifft die Verwendung von unter der Bezeichnung "Perlglanzpigmente für Kosmetika" bekannten Titandioxid/Glimmer-Perlglanz- oder Farbglanz-Pigmenten als bekannte Handelsprodukte als von umwelt-nicht-belastenden, schwermetallschadstoffreien, metallglänzenden Farbpigmenten in der Drucktechnikm insbesondere für Etiketten mit Gold- oder Metall. Effekt auf Glasflaschen oder Verpackungsmaterial verschiedener Art, oder auf Gegenständen wie Buchrücken, Leder, Kunststoffmaterial.The invention according to DE-A-3 224 558 relates to the use of titanium dioxide / mica pearlescent or colored gloss pigments known under the name "pearlescent pigments for cosmetics" as known commercial products as non-polluting, heavy metal pollutant-free, shiny metallic color pigments Printing technology especially for labels with gold or metal. Effect on glass bottles or packaging material of various types, or on objects such as book spines, leather, plastic material.
Es wird vorgeschlagen, diese in flüssige oder pastöse Streich- oder Druck-, oder Spritzfarben einzubringen und in dieser Form anzuwenden.It is proposed to apply these in liquid or pasty coating or printing or spraying inks and to use them in this form.
Ober diesen Stand der Technik geht die Erfindung hinaus. Es ist die Aufgabe der Erfindung, solche Perlglanzpigmente direkt anstelle der bisher zur Erzielung von Glanzeffekten verwendeten Bronzen auf Basis von Schwermetallen, wie Cu, einzusetzen.The invention goes beyond this prior art. It is the object of the invention to use pearlescent pigments of this type directly instead of the bronzes based on heavy metals, such as Cu, which have hitherto been used to achieve gloss effects.
Aus der DE-C-675 069 ist ein Bronzierauftragswerk bekannt für fliessfähige Schwermetallbronzen. Diese Vorrichtung soll die "Eigenart dieses schweren Bronzepulvers verhindern, dass es sich vor dem Austrittsspalt festsetzt".From DE-C-675 069 a bronzing applicator is known for flowable heavy metal bronzes. This device is said to "prevent the peculiarity of this heavy bronze powder from settling in front of the outlet gap".
Die Aufhebung der Verstopfung soll durch federnde Blechstreifen (d) an der schrägen Längswand bewirkt werden. Die konstruktive Ausbildung dieses Bronzebehälters ist eine andere, wie Figur 1 zeigt. Es ist die vordere Längswand steil und die Wand, an der sich die Blechstreifen befinden, schräg ausgebildet. Dagegen ist umgekehrt die vordere Wand des Bronzekastens gemäss dem Verfahren der Erfindung schräg gestellt und die Längswand an der Austrittsseite senkrecht ausgebildet. Es ist dadurch der Fliesswinkel nach diesem Stand der Technik grösser als 45°. Bei dem Fliesswinkel von 45° kann sich praktisch keine Staumenge der spezifisch leichten Bronze aus Perlglanzpigmenten bilden.The blockage should be removed by resilient metal strips (d) on the sloping longitudinal wall. The design of this bronze container is different, as shown in Figure 1. The front longitudinal wall is steep and the wall on which the sheet metal strips are located is formed obliquely. Conversely, according to the method of the invention, the front wall of the bronze box is inclined and the longitudinal wall on the outlet side is vertical. As a result, the flow angle according to this prior art is greater than 45 °. With a flow angle of 45 °, practically no storage volume of the specifically light bronze from pearlescent pigments can form.
Die GB-A-725 884 beschreibt einen Bronzekasten für schwere Metallbronzen mit 2 Schrägwänden. Der "scoop-on-pick-up-roller (d)" entspricht der üblichen Auftragswalze. Dieser "application roller" ist mit einem plüschartigen Überzug versehen, um dadurch eine bessere Haftung der schweren Bronze zu bewirken.GB-A-725 884 describes a bronze case for heavy metal bronzes with 2 sloping walls. The "scoop-on-pick-up roller (d)" corresponds to the usual application roller. This "application roller" is provided with a plush-like coating in order to improve the adhesion of the heavy bronze.
Diese Vorrichtung weist zahlreiche, unabhängig bewegliche Platten auf, die den Austritt der für sich fliessfähigen Bronzepartikel regeln sollen.This device has numerous, independently movable plates which are intended to regulate the outlet of the bronze particles which are free-flowing.
Es ist ebenfalls der Fliesswinkel grösser als 45° ausgebildet.The flow angle is also greater than 45 °.
In jüngerer Zeit sind durch die deutsche Offenlegungsschrift 31 37 808 (=EP-A-75 755) Perlglanz-Pigmente mit Goldeffekt bekannt geworden. Diese bestehen aus mit Titandioxyd beschichteten Glimmerschuppen, die auf der Ti02 - Schicht eine dünne Schicht von geglühtem Chromdioxyd und/oder Chromphosphat aufweisen.Pearlescent pigments with a gold effect have recently become known from German Offenlegungsschrift 31 37 808 (= EP-A-75 755). These consist of mica flakes coated with titanium dioxide, which have a thin layer of annealed chromium dioxide and / or chromium phosphate on the Ti0 2 layer.
Als Basispigmente werden calcinierte Rutil-Pigmente vorgeschlagen. Die Ti02-Schicht ist gering; diese soll 50-500 mg Ti02 betragen und zwar auf Glimmerschuppen von 5-200 Mikron Durchmesser bei 0,1-5 Mikron Dicke. Auf das beschichtete Glimmerpigment wird zur Erzielung des Goldeffektes eine dünne Schicht einer schwerlöslichen Cr-III-Verbindung aufgebracht und durch Glühbehandlung in Cr203 überführt. Diese Pigmente weisen einen wesentlich geringeren Schwermetallgehalt auf, der in der sehr dünen Deckschicht bereits unter dem zulässigen Grenzwert liegt.Calcined rutile pigments are proposed as the base pigments. The Ti0 2 layer is small; this should amount to 50-500 mg Ti0 2 on mica flakes with a diameter of 5-200 microns and a thickness of 0.1-5 microns. To achieve the gold effect, a thin layer of a poorly soluble Cr-III compound is applied to the coated mica pigment and converted into Cr 2 0 3 by annealing. These pigments have a much lower heavy metal content, which in the very thin top layer is already below the permissible limit.
Es besteht somit kein Grund dafür, auf Etiketten und anderen Drucken auf einen kräftigen Goldeffekt zu verzichten.There is therefore no reason to forego a strong gold effect on labels and other prints.
Es zeigt sich nun überraschend, dass es nicht möglich ist, diese Perlglanzpigmente mit Ti02-oder mit Wismutoxidchlorid-Beschichtung mit sehr geringem Metallgehalt als Bronzen technologisch einzusetzen.It is now surprisingly shown that it is not possible to use these pearlescent pigments with Ti0 2 or with bismuth oxychloride coating with a very low metal content as bronzes technologically.
Die Lösung der Aufgabe der Erfindung ist im kennzeichnenden Teil des Patentanspruches 1 definiert.The solution to the problem of the invention is defined in the characterizing part of
Dazu gehört in Verbindung mit der konstruktiven Ausbildung des Bronzekastens die Aufhebung der Agglomeratstruktur des Perlglanzpigmentes.In connection with the constructive design of the bronze box, this includes the abolition of the agglomerate structure of the pearlescent pigment.
Diese Lösung ist dadurch gekennzeichnet, dass das Perlglanzpigment dadurch in den fliessfähigen Zustand übergeführt wird, dass dieses über die Länge der Auftragswalze (1) aus dem darüber sich darüber befindenden Bronzekasten (2), der so tief heruntergesetzt ist, dass dieser, im Querschnitt gesehen, mit seiner senkrechten Wandfläche (4) und mit seiner zur Auftragswalze schrägen Wandfläche (5) als untere Begrenzung in Höhe des waagerechten Durchmessers (6) durch die Achse der Auftragswalze (1) angeordnet ist, auf die sich drehenden Fläche der Auftragswalze (1) aus dem Volumen des mit der spezifisch leichten Perlglanzpigment- Bronze gebildeten Bronzekeiles austritt, gesteuert durch verstellbare Schieber (3, 3a,... 3n) und über die Oberfläche der Auftragswalze (1) bis zum Öffnungsspalt (13) der Öffnungsschieber (3, 3a... 3n) mitgeführt wird, wobei der Bronzekeil (7), im Querschnitt gesehen, aus dem oberen Kreisbogenabschnitt (8) zwischen der Schrägfläche und der oberen Linie auf der Auftragswalze (1), aus der Schrägfläche (5) und durch die obere Linie (9) auf der Auftragswalze (1) gebildet ist, durch den Fliesswinkel (10) von 45°, der, im Querschnitt gesehen, aus der senkrechten Wandfläche (4) und der Linie (11) zum oberen Punkt (12) der Auftragswalze (1) im äusseren, waagerechten Punkt (13) auf der Auftragswalze (1) gebildet ist, kontinuierlich und gleichmässig abfliesst in einer solchen spezifischen Menge, dass die Druckbogen die vorher bestimmte Deckkraft erhalten, danach von den bronzierten Druckbogen die nicht klebende Menge des Perlglanzpigmentes durch Abbürsten entfernt, die bronzierten Druckbogen ausgeführt und gestapelt werden und das abgebürstete Perlglanzpigement in einen Auffangbehälter eingeführt wird.This solution is characterized in that the pearlescent pigment is converted into the flowable state by extending the length of the application roller (1) the bronze box (2) above it, which is set down so deep that, seen in cross-section, with its vertical wall surface (4) and with its wall surface (5) inclined to the applicator roller, as a lower limit at the height of the horizontal diameter (6 ) is arranged through the axis of the application roller (1), on the rotating surface of the application roller (1) emerges from the volume of the bronze wedge formed with the specifically light pearlescent pigment bronze, controlled by adjustable sliders (3, 3a, ... 3n ) and carried over the surface of the application roller (1) to the opening gap (13) of the opening slide (3, 3a ... 3n), the bronze wedge (7), seen in cross section, from the upper arc section (8) between the Inclined surface and the upper line on the application roller (1), from the inclined surface (5) and by the upper line (9) on the application roller (1) is formed by the flow angle (10) of 45 °, which, seen in cross section , a us of the vertical wall surface (4) and the line (11) to the upper point (12) of the application roller (1) in the outer, horizontal point (13) on the application roller (1) is formed, flows continuously and uniformly in such a specific amount that the printed sheets are given the previously determined opacity, then the non-adhesive amount of the pearlescent pigment is removed by brushing off the bronzed printed sheets, the bronzed printed sheets are carried out and stacked and the brushed pearlescent pigment is introduced into a collecting container.
Die Ausgestaltung des Verfahrens der Erfindung ergibt sich aus den bevorzugten Massnahmen des Unteranspruch. Der technische Effekt der Herbeiführung der Fliessfähigkeit aus dem nichtfliessfähigen Zustand der Perlglanzpigmente aus dem Bronzekasten beruht auf der Aufhebung der Agglomeratstruktur der einzelnen Partikelteilchen.The configuration of the method of the invention results from the preferred measures of the subclaim. The technical effect of creating the flowability from the non-flowable state of the pearlescent pigments from the bronze box is based on the elimination of the agglomerate structure of the individual particle particles.
Der "fliessfähige Zustand" nach dem Verfahren der Erfindung wird wie folgt deriniert:The "flowable state" according to the method of the invention is derininated as follows:
Auf einer schmalen nach oben gewölbten. Rundfläche, wie beispielsweise ein gerundetes Holz, oder Metall-Stück, oder behelfsmässig auch mittels des ausgestreckten Zeigeringers, wird durch Eintauchen in die Bronziermasse eine Probe entnommen, die praktisch die gewölbte Fläche als Haufwerk bedeckt. Der nicht fliessfähige Zustand ist dadurch definiert, dass die Bronziermasse nicht von der waagerecht gehaltenen Rundfläche abrinnt.On a narrow arched up. Round surface, such as a rounded piece of wood or metal, or makeshift also by means of the extended pointer ring, a sample is taken by immersing it in the bronzing compound, which practically covers the curved surface as a heap. The non-flowable state is defined by the fact that the bronzing compound does not run off the horizontally held round surface.
Kupferbronze nach dem Stand der Technik rinnt rasch von der Rundfläche ab und definiert den fliessfähigen Zustand.State-of-the-art copper bronze quickly runs off the round surface and defines the flowable state.
Solche Cu-Bronzen weisen beispielsweise einen Cu-Gehalt von 60 bis 85 Gew.-% auf. Es zeigt sich, dass abgebürstete Cu-Bronze nur langsam und unvollständig abfliesst. Diese ist nicht nur in seinem ursprünglichen Glanzeffekt in Richtung auf einen matten, unregelmässigen Glanzeffekt und in der Farbkraft verändert, sondern auch im ihrer Struktur, insbesondere durch Agglomeration der Primärteilchen.Such copper bronzes have, for example, a copper content of 60 to 85% by weight. It can be seen that brushed copper bronze flows slowly and incompletely. This has changed not only in its original gloss effect in the direction of a matt, irregular gloss effect and in the color strength, but also in its structure, in particular due to agglomeration of the primary particles.
Das Verfahren der Erfindung vesteht unter der technischen Massnahme der "Bronzierung" nicht nur das Aufbringen von Bronzen nach dem Stand der Technik, sondern auch im übertragenen Sinn das Aufbringen der Perlglanzpigmente ohne Cu-Gehalt und mit nur geringem Cr-Gehalt.The process of the invention means the technical measure of "bronzing" not only the application of bronzes according to the prior art, but also figuratively the application of the pearlescent pigments without Cu content and with only a low Cr content.
Der Fachwelt ist es bisher nicht gelungen, die Fliessfähigkeit mit der erforderlichen, hohen Genauigkeit für die kontinulierliche und gleichmässige Zufuhr der Perlglanzpigmente für die Bronzierung zu erreichen.The experts have so far not been able to achieve the flowability with the required high accuracy for the continuous and uniform supply of the pearlescent pigments for bronzing.
Die Figuren 1 und 2 erläutern die Arbeitsweise nach dem Verfahren der Erfindung. Figur 1 zeigt die konstruktive Ausbildung des Bronzekastens (2) über der Auftragswalze (1) im Querschnitt.Figures 1 and 2 explain the operation according to the method of the invention. Figure 1 shows the design of the bronze box (2) over the applicator roller (1) in cross section.
Figur 2 zeigt die Längsansicht der Anordnung des Bronzekastens ebenfalls in schematischer Anordnung.Figure 2 shows the longitudinal view of the arrangement of the bronze box also in a schematic arrangement.

Es werden beispielsweise bei einer Länge der Auftragswalze von 1,32 mm, bei einem Durchmesser der Auftragswalze (1) von 70 mm und bei der Länge der senkrechten Wandfläche (4) von 130 mm und der schrägen Wandfläche (5) von 160 mm, bei einer oberen Breite des Bronzierkastens (2) von 110 mm, ein Durchsatz von 1,3 bis 1,5 kg eines Cu-freien Perlglanzpigmentes als Bronze aus dem Bronzierkasten (2) auf die Auftragswalze (1) eingestellt.For example, with a length of the application roller of 1.32 mm, with a diameter of the application roller (1) of 70 mm and with the length of the vertical wall surface (4) of 130 mm and the inclined wall surface (5) of 160 mm an upper width of the bronzing box (2) of 110 mm, a throughput of 1.3 to 1.5 kg of a Cu-free pearlescent pigment as bronze from the bronzing box (2) to the application roller (1).
Mit dieser Menge der Bronziermasse werden 10002, entsprechend 1000 Druckbogen von je 1 m2 in 20 min bronziert.With this amount of bronzing compound 1000 2 , corresponding to 1000 printed sheets of 1 m 2 each, are bronzed in 20 min.
Es werden durch die über die Länge der Auftragswalze (1) verteilten 32 Schieber (3, 3a,... 3n) auf die Breite des durch Bronziermaschine durchlaufenden Druckbogens an den erforderlichen Stellen exakt die kontinuierlich und gleichmässig fliessenden Perlglanzpigmente dosiert aufgegeben.Through the 32 slides (3, 3a, ... 3n) distributed over the length of the application roller (1), the continuously and uniformly flowing pearlescent pigments are metered in precisely at the required points across the width of the printing sheet passing through the bronzing machine.
