Abstract

A process is disclosed for transferring in particular colour reproductions to smooth substrates by transferring the reproduction by a photocopying process to a transfer layer applied on a carrier. The transfer layer carrying the transferred reproduction (image) is released by a wet process from the carrier, is applied on the substrate, then cured. The transfer layer has a sandwich structure with at least two layers, one (first) outer layer that fixes in place and seals when exposed to heat the pigments transferred by photocopying and a (second) layer arranged beneath the outer layer that forms a curing adhesive layer which cross-links with the substrate, fixing in place the transfer layer on the substrate.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Übertragen von insbesondere farbigen Darstellungen auf glatte Unterlagen, indem die Darstellung auf eine auf einen Träger aufgebrachte Transferschicht im Kopierverfahren übertragen wird. Ferner bezieht sich die Erfindung auf eine Transferschicht, die auf einem Träger wie holzfreiem Papier angeordnet ist, zum Fixieren von im Kopierverfahren übertragenen Darstellungen.The invention relates to a method for transferring, in particular, colored representations to smooth documents, in that the representation is transferred to a transfer layer applied to a carrier in the copying process. Furthermore, the invention relates to a transfer layer, which is arranged on a carrier such as wood-free paper, for fixing representations transmitted in the copying process.

Es sind Verfahren zum Übertragen vom Darstellungen wie Motiven auf flächige Unterlagen mit poröser Oberfläche wie Textilgut bekannt, wobei die Darstellung auf ein Papier durch Trockenkopieren übertragen und von diesem auf die Unterlagen mittels Wärme aufgebracht wird (WO 91/00385 oder Xerox Disclosure Journal Volume 5 Number 3 May/June 1980, Seite 229).Methods are known for transferring representations such as motifs onto flat supports with a porous surface such as textile goods, the representation being transferred onto a paper by dry copying and being applied by heat onto the supports (WO 91/00385 or Xerox Disclosure Journal Volume 5 Number 3 May / June 1980, page 229).

Um die Darstellungen zu übertragen, muß einerseits die Unterlage eine poröse Oberfläche aufweisen und andererseits ist eine Heiß- oder Warmpresse notwendig, um bei erheblicher Druckeinwirkung die Übertragung auf die Unterlage vorzunehmen.In order to transfer the representations, on the one hand the base must have a porous surface and on the other hand a hot or hot press is necessary in order to carry out the transfer to the base if there is considerable pressure.

Es sind auch Naßverfahren bekannt, um z. B. Abziehbilder auf Unterlagen aufzubringen. Dabei werden bedruckte Bilder mittels eines Haftmittels auf ein Trägermaterial aufgebracht, um zum Übertragen das Bild von dem Träger zu lösen und anschließend das Bild mit der Klebeschicht auf der Unterlage aufzubringen und dann zu trocknen. Dabei stehen jedoch keine individuellen, selbst zugestaltenden Darstellungen zur Verfügung.Wet processes are also known, e.g. B. Apply decals to documents. Printed images are applied to a carrier material by means of an adhesive in order to detach the image from the carrier for transfer and then apply the image with the adhesive layer on the base and then dry it. However, there are no individual, self-designed representations available.

Aus der EP 0 118 084 A1 ist ein Träger für Abzieh- oder Abschiebebilder bekannt, auf dem eine wasserlösliche Trennschicht zur einseitigen Aufnahme einer ablösbaren Druck-und/oder Lackschicht aufgebracht ist. In der EP 0 380 356 A2 ist ein Abziehbild bzw. ein Verfahren zum Übertragen von z. B. xerographisch hergestellten Bildern beschrieben. Als Träger wird ein Papier benutzt, daß derart mit Feststoffen getränkt ist, daß eine Porösität nicht vorliegt. Auf den Träger unmittelbar oder auf einem auf diesem aufgebrachten Kunststoffilm wird das zu übertragende Bild aufgebracht. In ersterem Fall muß das Bild anschließend noch mit einem Kunststoffilm abgedeckt werden. Sodann erfolgt eine Übertragung auf einen porösen Gegenstand, wobei der Kunststoffilm stets außen liegt.EP 0 118 084 A1 discloses a support for decals or decals on which a water-soluble separating layer for one-sided reception of a detachable printing and / or lacquer layer is applied. EP 0 380 356 A2 describes a decal or a method for transferring e.g. B. described xerographically produced images. A paper is used as the carrier which is soaked with solids in such a way that there is no porosity. The image to be transferred is applied to the carrier directly or on a plastic film applied thereon. In the former case, the picture must then be covered with a plastic film. Then there is a transfer to a porous object, the plastic film always being on the outside.

Der vorliegenden Erfindung liegt unter anderem das Problem zugrunde, ein Verfahren der eingangs gennanten Art so weiterzubilden, daß beliebige Darstellungen auf eine Unterlage mit glatter, im wesentlichen nichtporöser Oberfläche übertragen werden können, wobei die übertragene Darstellung weitgehend kratzfest auf der Unterlage angeordnet werden soll. Dabei soll verfahrensmäßig eine Vereinfachung gegeben sein, so daß auch Laien eine entsprechende Übertragung vornehmen können.The present invention is based, inter alia, on the problem of developing a method of the type mentioned at the outset in such a way that any representations can be transferred to a support with a smooth, essentially non-porous surface, the transferred display being to be arranged largely scratch-resistant on the support. In terms of procedure, there should be a simplification so that even laypersons can carry out a corresponding transfer.

Das Problem wird erfindungsgemäß im wesentlichen dadurch gelöst, daß das Bild auf oder in die Transfertschicht kopiert wird, in der durch das Kopierverfahren übertragene Pigmente lagefixiert werden, und daß die die übertragene Darstellung (Bild) aufweisende Transferschicht zunächst im Naßverfahren von dem Träger gelöst, sodann mit der Transferschicht zur Unterlage auf diese aufgebracht und anschließend gehärtet wird. Dabei wird vorzugsweise ein Temperaturbereich zwischen 100 °C und 200 °C, vorzugsweise im Bereich von 120 °C bis 160 °C, insbesondere jedoch bei ca 140 °C gewählt.The problem is essentially solved according to the invention in that the image is copied onto or into the transfer layer, in which pigments transferred by the copying process are fixed in position, and in that the transfer layer having the transferred representation (image) is first removed from the support by the wet process, then with the Transfer layer to the base is applied to this and then hardened. A temperature range between 100.degree. C. and 200.degree. C., preferably in the range from 120.degree. C. to 160.degree. C., but in particular around 140.degree. C., is preferably selected.

Unter Lösen wird dabei ein seitliches Wegschieben von dem Träger verstanden. Die Transferschicht wird ferner auf die Unterlage geschoben.Loosening is understood to mean a lateral pushing away from the carrier. The transfer layer is also pushed onto the pad.

Erfindungsgemäß kann folglich eine beliebige Darstellung, also persönliche Bilder, Zeitungsausschnitte, Zeichnungen o. ä. vorzugsweise im xerographischen Kopierverfahren auf die auf dem Träger befindliche Transferschicht übertragen werden, um diese als Kaltabziehbild im Naßverfahren zu lösen und auf eine glatte, im wesentlichen nicht poröse Unterlage wie z. B. Glas, Porzellan, Keramik, Metall, Emaille oder Kunststoff aufzubringen, d.h. aufzuschieben, zu trocknen (Feuchtigkeit entfernen) und dann auszuhärten.According to the invention, any representation, that is to say personal images, newspaper clippings, drawings or the like, can preferably be transferred to the transfer layer on the carrier in a xerographic copying process in order to solve this as a cold transfer in the wet process and on a smooth, essentially non-porous base such as B. glass, porcelain, ceramic, metal, enamel or plastic, i.e. postpone, dry (remove moisture) and then harden.

Die Darstellung wird in eine vorzugsweise in Plexigum-Material aufweisende Schicht der Transferschicht kopiert, um durch das Kopierverfahren übertragene Pigmente zu fixieren und anschließend durch Wärmeeinwirkung die Pigmente zu umschließen, also quasi versiegeln zu lassen. Hierdurch ergibt sich eine hohe Beständigkeit des Bildes sowie eine glatte Oberfläche.The representation is copied into a layer of the transfer layer, preferably made of plexigum material, in order to fix pigments transferred by the copying process and then to enclose the pigments by the action of heat, that is to say to allow them to be sealed. This results in a high durability of the picture and a smooth surface.

Vorzugsweise befindet sich zwischen der Transferschicht und dein Träger eine dextrinund/oder fettalkoholhaltige Trennschicht, durch die bei Zuführen von Feuchtigkeit die Transferschicht von dein Träger lösbar ist.There is preferably a separating layer containing dextrin and / or fatty alcohol between the transfer layer and your support, through which the transfer layer can be detached from the support when moisture is added.

Die Erfindung bezieht sich auch auf eine Transfeischicht, die auf einem Träger wie holzfreiem Papier von maximal 120 g pro m2 angeordnet ist, zum Fixieren von im Kopierverfahren übertragenen Darstellungen, wobei sich die Transferschicht dadurch auszeichnet. daß diese einen Sandwich-Aufbau umfassend zumindest zwei Schichten besitzt, daß eine (erste) äußere Schicht durch das Kopierverfahren übertragene Pigmente lagefixiert und bei Wärmeeinwirkung umschließt und daß eine unterhalb der äußeren Schicht angeordnete (zweite) Schicht eine durch Erwärmen aushärtende Haftschicht ist, die zum Lagefixieren der Transferschicht auf einer Unterlage sich mit dieser vernetzt.The invention also relates to a transfer layer, which is arranged on a support such as wood-free paper of a maximum of 120 g per m 2 , for fixing representations transmitted in the copying process, the transfer layer being distinguished thereby. that this has a sandwich structure comprising at least two layers has that a (first) outer layer fixes pigments transferred by the copying process and encloses them when exposed to heat, and that a (second) layer arranged below the outer layer is a heat-curing adhesive layer that crosslinks with the substrate to fix the transfer layer on it .

Die erste Schicht besteht aus Plexigum-Material auf Lösungsmittelbasis mit Weichmacher. Dabei weist die erste Schicht eine Dicke d von in etwa 0,10 ≤ d ≤ 0,20 mm, vorzugsweise von in etwa d = 0,15 mm auf.The first layer consists of solvent-based Plexigum material with plasticizer. The first layer has a thickness d of approximately 0.10 d d 0 0.20 mm, preferably approximately d = 0.15 mm.

Die Haftschicht ist auf Kunstharzbasis aufgebaut. Vorzugsweise besteht die Haftschicht aus einer Mischung aus Kunstharz mit Härterzusatz und Plexigum auf Lösungsmittel basis mit Weichmachern. Dabei kann der Kunstharz- und der Plexigumanteil in etwa gleich groß sein. Die Haftschicht kann eine Dicke d von 0,02 ≤ d ≤ 0,08 mm, vorzugsweise von in etwa d = 0,05 mm aufweisen.The adhesive layer is based on synthetic resin. The adhesive layer preferably consists of a mixture of synthetic resin with hardener additive and plexigum on solvent base with plasticizers. The proportion of synthetic resin and plexiglass can be approximately the same size. The adhesive layer can have a thickness d of 0.02 d d 0,0 0.08 mm, preferably of approximately d = 0.05 mm.

Ferner kann zwischen der Transferschicht und dem Träger eine Trennschicht angeordnet sein, die auf Dextrin- oder Fettalkoholbasis aufgebaut ist.Furthermore, a separating layer which is based on dextrin or fatty alcohol can be arranged between the transfer layer and the carrier.

Als Träger wie holzfreies Papier kann an und für sich bekanntes Abziehbilderpapier benutzt werden, welches unter der Bezeichnungen "Meta" der Fa. Hoffmann und Engelmann oder "Twincal" der Fa. Britans mit einem Flächengewicht von maximal 120 g pro m2 bekannt ist.As a carrier such as wood-free paper, decal paper known per se can be used, which is known under the names "Meta" from Hoffmann and Engelmann or "Twincal" from Britans with a basis weight of maximum 120 g per m 2 .

Die zwischen dem Träger und der Transferschicht vorhandene Trennschicht weist Dextrin und/oder Fettalkohol auf. Hierdurch ist ein einfaches Lösen der Transferschicht von dem Träger mittels Feuchtigkeit möglich. Unter Feuchtigkeit wird hier nicht nur Wasser, sondern auch Wasserdampf verstanden, um auf diese Weise das Zwischenträgermaterial zu lösen.The separating layer between the carrier and the transfer layer has dextrin and / or fatty alcohol. This allows the transfer layer to be easily detached from the carrier by means of moisture. Moisture is understood here not only to mean water, but also water vapor in order to dissolve the intermediate carrier material in this way.

Das erfindungsgemäße Verfahren wird nachstehend anhand eines Beispiels erläutert, aus dem sich weitere Einzelheiten, Vorteil und Merkmale der Erindung ergeben, die auch aus den Ansprüchen, den diesen zu entnehmenden Merkmalen - für sich und/oder in Kombination - ersichtlich werden.The method according to the invention is explained below on the basis of an example from which further details, advantages and features of the invention result, which also become apparent from the claims, the features to be extracted from them - individually and / or in combination.

Eine zu übertragende Darstellung wird auf einen Trockenkopierer gelegt, um die Darstellung auf eine auf einem Träger angeordnete Transferschicht zu kopieren. Als Träger wird ein an und für sich bekanntes Abziehbilderpapier mit einem Flächengewicht von max. 120 g pro m2 benutzt, welches holzfrei ist und unter den Bezeichnungen "Meta" und "Twincal" käuflich erwerblich ist. Auf diesem Trägermaterial befindet sich eine dextrin- und/oder fettalkoholmaterialhaltige Trennmittelschicht, durch die die Transferschicht bei Feuchtigkeitseinwirkung von dem Träger trennbar ist.A representation to be transferred is placed on a dry copier in order to copy the representation onto a transfer layer arranged on a carrier. A decal paper known per se with a basis weight of max. 120 g per m 2 used, which is wood-free and is commercially available under the names "Meta" and "Twincal". There is one on this carrier material Release agent layer containing dextrin and / or fatty alcohol material, through which the transfer layer can be separated from the carrier when exposed to moisture.

Die Transferschicht besitzt eine Sandwich-Struktur mit zumindest einer äußeren Fixierschicht und eine von dieser abgedeckten Haftschicht.The transfer layer has a sandwich structure with at least one outer fixing layer and an adhesive layer covered by this.

Die Fixierschicht besteht aus Plexigum auf Lösemittelbasis mit Weichmacher. Diese Schicht ist relativ weich und daher geeignet, den Toner aufzunehmen und zu fixieren. Die Schichtstärke beträgt ca. 0,15 mm.The fixing layer consists of solvent-based plexigum with plasticizer. This layer is relatively soft and therefore suitable for absorbing and fixing the toner. The layer thickness is approximately 0.15 mm.

Die Haftschicht besteht aus einer ca. 1:1 Mischung von Kunstharz mit entsprechendem Härterzusatz und Plexigum auf Lösemittelbasis mit Weichmacher. Diese Schicht ist so gestaltet, daß sie relativ hart und spröde ist, aber sehr gute Vernetzungseigenschaften mit der neuen Unterlage besitzt. Die Schichtstärke beträgt ca. 0,05 mm.The adhesive layer consists of an approx. 1: 1 mixture of synthetic resin with the corresponding hardener additive and solvent-based plexigum with plasticizer. This layer is designed so that it is relatively hard and brittle, but has very good cross-linking properties with the new base. The layer thickness is approximately 0.05 mm.

Der Sandwich-Aufbau aus den zumindest übereinanderliegenden Schichten ist notwendig, da:

  • a) eine einzige, zusammengemischte Schicht immer noch zu hart und spröde ist, um sich übertragen zu lassen,
  • b) sich keine übertragbare Schichtstärke erzielen lassen würde,
  • c) der Kopiertoner nicht mehr sauber fixieren würde und
  • d) sich keine weißen oder Effektschichten herstellen lassen würden.
The sandwich structure from the layers that are at least one above the other is necessary because:
  • a) a single layer mixed together is still too hard and brittle to be transferred,
  • b) no transferable layer thickness would be achievable,
  • c) the copy toner would no longer fix properly and
  • d) no white or effect layers could be produced.

Nachdem die Darstellung auf die Transferschicht übertragen ist, wird das Bild entlang seiner Umrisse ausgeschnitten und in lauwarmes Wasser gelegt. Nach ca. 1 Minute löst sich die Transferschicht von dem Träger dergestalt, daß sich die das Bild aufweisende Transferschicht von dem Träger wegschieben läßt. Die freie Transferschicht mit dem Bild wird sodann unmittelbar auf eine mit dem Bild zu versehende Unterlage geschoben, die eine glatte, im wesentlichen nicht poröse Oberfläche aufweist. Mit einem Gummirakel oder einem weichen Tuch wird die unter und über der so übertragenen Schicht befindliche Feuchtigkeit wie Wasser entfernt.After the image has been transferred to the transfer layer, the image is cut out along its outline and placed in lukewarm water. After about 1 minute, the transfer layer detaches from the carrier in such a way that the transfer layer having the image can be pushed away from the carrier. The free transfer layer with the The image is then pushed directly onto a base to be provided with the image, which has a smooth, essentially non-porous surface. With a rubber squeegee or a soft cloth, the moisture under and above the layer thus transferred is removed like water.

Auf diese Weise ist das Bild bereits auf der Unterlage derart fixiert, daß ein Verschieben nicht mehr möglich ist.In this way, the image is already fixed on the base in such a way that it is no longer possible to move it.

Um ein Aushärten der Transferschicht, also des Bildes zu erzielen, erfolgt ein chemischer Härtungsprozeß, der bei einer Temperatur zwischen 140 °C und 180 °C in der Fixiereinheit des Kopiersystems gestartet wird und ohne weitere Zuführung von Hitze 4 bis 6 Tage bis zur endgültigen Aushärtung andauern würde. Diese Zeit kann man jedoch verkürzen, wenn man nach dem Anordnen des Zwischenträgermaterials auf der Unterlage Wärme im Bereich von ca. 140 °C über einen Zeitraum von ca. 10 Minuten zuführt.In order to harden the transfer layer, that is to say the image, a chemical hardening process takes place, which is started at a temperature between 140 ° C. and 180 ° C. in the fixing unit of the copying system and without further application of heat for 4 to 6 days until the final hardening would last. This time can be shortened, however, if heat is placed in the range of approx. 140 ° C over a period of approx. 10 minutes after arranging the intermediate carrier material on the base.
