Definitions
- the present invention relates to new transfer media, especially those made of paper for dry transfer printing of polyacrylonitrile fibers.
- the new transfer printing carriers are characterized by the fact that on a flexible, heat-stable base, for example on a paper web, they carry a volatile, ie sublimable or vaporizable pattern at 180 ° to 210 ° C mix of dyes of the two types contains, in which A represents an ether group (for example a methoxy, phenoxy, hydroxyethoxy group), n represents an integer of at most 4, X represents a hydrogen atom or a low molecular weight, optionally substituted alkyl group and Y represents a low molecular weight, optionally substituted alkyl group, where the dyes of types I and II present in the mixture are in a ratio of 1: 3 to 3: 1 to one another.
- the dye of one type is at least 25% by weight, but preferably at least 35% by weight.
- several dyes of one type with one or more dyes of the other can also be present in the specified ratio.
- the invention also relates to a method for printing sheetlike structures made of synthetic or partially synthetic polymeric materials according to the transfer printing principle, which is characterized in that transfer printing supports are used which carry a volatile pattern at 180 ° to 210 ° C, the red element of which consists of a mixture of Dyes of the two types I and II in a ratio of at least 1: 3 to at most 3: 1 of one type of dye to the other.
- Another object of the invention are printing inks or printing pastes for transfer printing and the substrates, in particular polyacrylonitrile fabrics, knitted fabrics or velvet, as well as more or less multi-pole plush and high-density wallpapers made of polyacrylonitrile and polyacrylonitrile-like materials that have been printed with such transfer printing media, ie that they have a mixture of the type specified as the red element.
- auxiliary carriers transfer printing carriers
- transfer printing carriers which are printed with suitable printing inks, are brought into close contact with the substrate to be printed, whereupon the dye is transferred from the carrier to the substrate under the action of heat and possibly pressure.
- Transfer under reduced pressure e.g. at 80 to 110 mbar is also possible, the transfer temperature being kept lower and / or the transfer speed being increased.
- Sheet-like structures such as paper, cellophane, cotton fabric, linen fabric, metal foils etc. come into consideration as auxiliary carriers. Paper is preferred.
- the printing inks can be printed using customary printing processes.
- composition of the printing inks depends, among other things, on the type of substrate, the printing process and the carrier material.
- Rotogravure and rotary film printing are particularly suitable printing processes for the production of printed paper auxiliary substrates.
- Suitable substrates are preferably sheet-like structures, such as nonwovens, felts, furs, foils and, in particular, woven and knitted fabrics made of polyacrylonitrile and polyacrylonitrile-like materials (modacrylic).
- the production of the starting dyes is known per se and a large number of dyes of the types mentioned are available on the market. Only the Disperse Red 4, 55, 55: 1, 60 and 91 listed in the Color Index of the Society of Dyers and Colorists should be mentioned.
- the tricyanovinyl dyes of type II are known from the patent literature (see, for example, German Offenlegungsschrift No. 2,741,392 ).
- the dye mixtures can be prepared by various methods.
- the transfer printing medium according to the invention is obtained by customary printing methods.
- These supports produce brilliant red patterns on polyacrylonitrile materials using the transfer printing method, whose lightfastness is surprisingly higher than that of the patterns obtained with the individual dyes of type II.
- the brilliance of the swatches is also significantly better than that of the swatches of type I dyes and, for practical purposes, almost equal to that of the corresponding swatches of type II dyes.
- the rub fastness is excellent.
- Example 1 35 parts of 1-amino-2-methoxy-4-hydroxyanthraquinone are mixed with 40 parts of the dye of the formula 50 parts of a dispersant (lignin sulfonate or condensation product of naphthalenesulfonic acid and formaldehyde) and 100 parts by volume of water are mixed and converted into a finely divided form in a ball mill by grinding for 10 hours.
- a dispersant lignin sulfonate or condensation product of naphthalenesulfonic acid and formaldehyde
- the dispersion thus obtained containing about 30% raw color, is pasted with 400 parts of a 10% locust bean gum ether thickener and 500 parts by volume of water.
- This printing paste is used to print on paper using rotary film printing or gravure printing. If you press this paper for 15 to 60 seconds at 200 ° C with a textile made of polyacrylonitrile fibers, you get a strong brilliant red print with excellent lightfastness.
- Example 2 20 parts of 1-amino-2ß-hydroxyethyloxy-4-hydroxyanthraquinone are mixed with 30 parts of the dye of the formula 5 to 10 parts of an emulsifier mixture of ethoxylated nonylphenol
- the printing ink obtained in this way can be used for gravure printing on papers.
- textiles made of polyacrylonitrile, for example knitted fabrics or velvet can be printed in the transfer process at 190 ° under 100 mbar and a contact pressure of the follower on the transfer paper of approximately 1 g / cm 2, and brilliant red prints of excellent fastness are obtained.

Description
Die vorliegende Erfindung betrifft neue Umdruckträger, vor allem solche aus Papier zum trockenen Transferdruck von Polyacrylnitrilfasern.The present invention relates to new transfer media, especially those made of paper for dry transfer printing of polyacrylonitrile fibers.
Die für Polyesterfaser sehr verbreitete Transfer-Drucktechnik, wonach Polyesterfasermaterialien trocken bei 200° bis 210° C in Kontakt mit einem das zu transferierende Muster tragenden Träger, z.B. nach dem im französischen Patent 1 585 119 beschriebenen Verfahren, bedruckt werden, hat sich bei den Textilmaterialien aus Polyacrylnitril nicht richtig durchgesetzt. Sowohl die Umdruckträger der französischen Patente 2 262 612, womit bei tieferen Temperaturen gearbeitet werden kann, als auch diejenigen der französischen Patente 2 243 831 und 2 310 225, welche kationische Farbstoffe aufweisen, sind von der Kundschaft nie richtig angenommen worden. Dies hauptsächlich wegen der mangelnden Lichtechtheit des Rotelementes bei den transferierbaren kationischen Farbstoffen und auch, weil es mit den mittels transferierbarer, an sich auf Polyacrylnitril hinlänglich lichtechten Dispersionsfarbstoffe bedruckten Umdruckträgern nicht möglich war, brillantrote Muster zu erzeugen.The transfer printing technique which is very common for polyester fiber, according to which polyester fiber materials dry at 200 ° to 210 ° C in contact with a carrier carrying the pattern to be transferred, e.g. by the process described in French Patent 1,585,119 has not been properly established in polyacrylonitrile textile materials. Both the transfer carriers of French patents 2 262 612, which can be used at lower temperatures, and those of French patents 2 243 831 and 2 310 225, which contain cationic dyes, have never been properly accepted by customers. This is mainly due to the poor lightfastness of the red element in the transferable cationic dyes and also because it was not possible to produce brilliant red patterns with the transfer printing substrates, which were adequately light-fast on polyacrylonitrile and were printed on polyacrylonitrile.
Diese Mängel der bekannten Technik werden durch die neuen Umdruckträger der vorliegenden Erfindung behoben.These shortcomings of the known technology are remedied by the new transfer printing medium of the present invention.
Die neuen Umdruckträger sind dadurch gekennzeichnet, dass sie auf eine flexible, hitzestabile Unterlage, z.B. auf eine Papierbahn, ein bei 180° bis 210° C flüchtiges, d.h. sublimierbares oder verdampfbares Muster tragen, das als Rotelement ein Gemisch von Farbstoffen der beiden Typen
Die Erfindung betrifft ebenfalls ein Verfahren zum Bedrucken von flächenförmigen Gebilden aus synthetischen oder teilsynthetischen polymeren Materialien nach dem Transferdruckprinzip, welches dadurch gekennzeichnet ist, dass man Transferdruckträger verwendet, die ein bei 180° bis 210° C flüchtiges Muster tragen, dessen Rotelement aus einem Gemisch von Farbstoffen der beiden Typen I und II im Verhältnis von mindestens 1 : 3 bis höchstens 3 : 1 des einen Farbstofftyps zum anderen besteht.The invention also relates to a method for printing sheetlike structures made of synthetic or partially synthetic polymeric materials according to the transfer printing principle, which is characterized in that transfer printing supports are used which carry a volatile pattern at 180 ° to 210 ° C, the red element of which consists of a mixture of Dyes of the two types I and II in a ratio of at least 1: 3 to at most 3: 1 of one type of dye to the other.
Ein weiterer Gegenstand der Erfindung sind Drucktinten bzw. Druckpasten für den Transferdruck und die Substrate, insbesondere Polyacrylnitrilgewebe, -gewirke oder -samt sowie mehr oder weniger hochpoligen Plüsch und hochschäftige Tapeten aus Polyacrylnitril und polyacrylnitrilähnlichen Materialien, die mit derartigen Transferdruckträgern bedruckt worden sind, d.h. dass sie als Rotelement ein Gemisch der angegebenen Art aufweisen.Another object of the invention are printing inks or printing pastes for transfer printing and the substrates, in particular polyacrylonitrile fabrics, knitted fabrics or velvet, as well as more or less multi-pole plush and high-density wallpapers made of polyacrylonitrile and polyacrylonitrile-like materials that have been printed with such transfer printing media, ie that they have a mixture of the type specified as the red element.
Das Transferdruckverfahren ist im allgemeinen bekannt (vgl. z.B. Colour Index, 3. Ausgabe, Bd. 2, Seite 2480) und beispielsweise detailliert-in den Französischen Patentschriften 1 223 330, 1 334 829 und 1 585 119 beschrieben. Dabei werden sogenannte Hilfsträger (Umdruckträger), die mit geeigneten Drucktinten bedruckt sind, in einen engen Kontakt mit dem zu bedruckenden Substrat gebracht, worauf unter Wärme- und gegebenenfalls Druckeinwirkung der Farbstoff von dem Träger auf das Substrat transferiert wird. Transferierung unter vermindertem Druck z.B. bei 80 bis 110 mbar ist ebenfalls möglich, wobei die Transfertemperatur tiefer gehalten und/oder die Transfergeschwindigkeit erhöht werden kann.The transfer printing process is generally known (see, for example, Color Index, 3rd edition, vol. 2, page 2480) and is described in detail, for example, in French patents 1 223 330, 1 334 829 and 1 585 119. So-called auxiliary carriers (transfer printing carriers), which are printed with suitable printing inks, are brought into close contact with the substrate to be printed, whereupon the dye is transferred from the carrier to the substrate under the action of heat and possibly pressure. Transfer under reduced pressure e.g. at 80 to 110 mbar is also possible, the transfer temperature being kept lower and / or the transfer speed being increased.
Als Hilfsträger kommen flächenförmige Gebilde, wie Papier, Cellophan, Baumwollgewebe, Leinengewebe, Metallfolien usw. in Betracht. Bevorzugt wird Papier.Sheet-like structures such as paper, cellophane, cotton fabric, linen fabric, metal foils etc. come into consideration as auxiliary carriers. Paper is preferred.
Die Druckfarben können nach üblichen Druckverfahren verdruckt werden.The printing inks can be printed using customary printing processes.
Die Zusammensetzung der Drucktinten richtet sich unter anderem nach der Art des Substrates, des Druckverfahrens und des Trägermaterials.The composition of the printing inks depends, among other things, on the type of substrate, the printing process and the carrier material.
Besonders geeignete Druckverfahren zur Herstellung von bedruckten Papierhilfsträgern sind der Tiefdruck und der Rotationsfilmdruck.Rotogravure and rotary film printing are particularly suitable printing processes for the production of printed paper auxiliary substrates.
Geeignete Substrate sind vorzugsweise flächenförmige Gebilde, wie Vliese, Filze, Pelze, Folien und vor allem Gewebe und Gewirke aus Polyacrylnitril und polyacrylnitrilähnlichen Materialien (Modacryl). Die Herstellung der Ausgangsfarbstoffe ist an sich bekannt und es sind sehr viele Farbstoffe der erwähnten Typen auf dem Markt erhältlich. Erwähnt seien nur die im Colour Index der Society of Dyers and Colourists aufgeführten Disperse Red 4, 55, 55:1, 60 und 91. Die Tricyanovinyl-Farbstoffe vom Typus II sind aus der Patentliteratur bekannt (s. z.B. die deutsche Offenlegungsschrift Nr. 2 741 392).Suitable substrates are preferably sheet-like structures, such as nonwovens, felts, furs, foils and, in particular, woven and knitted fabrics made of polyacrylonitrile and polyacrylonitrile-like materials (modacrylic). The production of the starting dyes is known per se and a large number of dyes of the types mentioned are available on the market. Only the Disperse Red 4, 55, 55: 1, 60 and 91 listed in the Color Index of the Society of Dyers and Colorists should be mentioned. The tricyanovinyl dyes of type II are known from the patent literature (see, for example, German Offenlegungsschrift No. 2,741,392 ).
Die Herstellung der Farbstoff-Mischungen kann nach verschiedenen Methoden erfolgen.The dye mixtures can be prepared by various methods.
Neben dem mechanischen Abmischen der trockenen Einzelkomponenten nach der Herstellung der Einzelfarbstoffe kommt auch das Mi- - schen von mindestens zwei flüssigen Druckfarben in Betracht, welche je mindestens einen Farbstoff eines der angegebenen Typen enthalten. Dabei sind selbstverständlich die Mengen der beiden Druckfarben jeweils so zu wählen, dass unter Berücksichtigung der Farbstoffkonzentration nach dem Mischen eine Druckfarbe entsteht, die zwei Farbstoffe der angegebenen Art im angegebenen Verhältnis aufweist.In addition to the mechanical mixing of the dry individual components after the production of the individual dyes, it is also possible to mix at least two liquid printing inks, each of which contains at least one dye of one of the specified types. The quantities of the two printing inks are of course to be selected such that, taking into account the dye concentration, a printing ink is formed after mixing which has two dyes of the specified type in the specified ratio.
Mit diesen Druckfarben erhält man nach üblichen Druckmethoden die erfindungsgemässen Transferdruckträger. Diese Träger ergeben auf Polyacrylnitrilmaterialien nach der Transferdruckmethode brillantrote Muster, deren Lichtechtheit überraschenderweise höher liegt als diejenige der Muster, die man mit den einzelnen Farbstoffen vom Typ II erhält. Die Brillanz der Muster ist ebenfalls bedeutend besser als jene der Muster aus Farbstoffen des Typs I und für praktische Zwecke derjenigen der entsprechenden Muster aus Farbstoffen des Typs II fast ebenbürtig. Die Reibechtheit ist ausgezeichnet.With these printing inks, the transfer printing medium according to the invention is obtained by customary printing methods. These supports produce brilliant red patterns on polyacrylonitrile materials using the transfer printing method, whose lightfastness is surprisingly higher than that of the patterns obtained with the individual dyes of type II. The brilliance of the swatches is also significantly better than that of the swatches of type I dyes and, for practical purposes, almost equal to that of the corresponding swatches of type II dyes. The rub fastness is excellent.
In den nachfolgenden Beispielen bedeuten, falls nichts anderes angegeben ist, die Teile Gewichtsteile, die Prozente Gewichtsprozente, und die Temperaturen sind in Celsiusgraden aufgeführt.In the examples below, unless otherwise stated, parts are parts by weight, percentages are percentages by weight, and temperatures are listed in degrees Celsius.
Beispiel 1: 35 Teile des 1-Amino-2-methoxy-4-hydroxy-anthrachinons werden mit 40 Teilen des Farbstoffes der Formel
Die so erhaltene, ca. 30 % Rohfarbe enthaltende Dispersion wird mit 400 Teilen einer 10 %igen Johannisbrotkernmehlätherverdickung und 500 Volumteilen Wasser angeteigt.The dispersion thus obtained, containing about 30% raw color, is pasted with 400 parts of a 10% locust bean gum ether thickener and 500 parts by volume of water.
Mit dieser Druckpaste wird ein Papier im Rotationsfilmdruck oder im Tiefdruckverfahren bedruckt. Verpresst man dieses Papier während 15 bis 60 Sekunden bei 200° C mit einem Textil aus Polyacrylnitrilfasern, so erhält man einen kräftigen brillantroten Druck von ausgezeichneter Lichtechtheit.This printing paste is used to print on paper using rotary film printing or gravure printing. If you press this paper for 15 to 60 seconds at 200 ° C with a textile made of polyacrylonitrile fibers, you get a strong brilliant red print with excellent lightfastness.
Beispiel 2: 20 Teile des 1-Amino-2ß-hydroxyäthyloxy-4-hydroxyanthra- chinons werden mit 30 Teilen des Farbstoffes der Formel
(4 bis 12 Mol Aethylenoxyd) in Wasser angeteigt. Man setzt 50 Teile Aethylcellulose N4 (Hercules Powder) zu, knetet zwei Stunden lang und mahlt anschliessend auf einer üblichen Mühle.(4 to 12 moles of ethylene oxide) pasted in water. 50 parts of ethyl cellulose N 4 (Hercules Powder) are added, the mixture is kneaded for two hours and then ground in a conventional mill.
Das so erhaltene Farbstoffpulver gibt man unter Rühren in ein Gemisch aus
- 730 g Aethanol
- 50 g Aethylenglykol und
- 20 g Aethylcellulose N 22 (Hercules Powder).
- 730 g of ethanol
- 50 g of ethylene glycol and
- 20 g of ethyl cellulose N 22 (Hercules Powder).
Mit der so erhaltenen Druckfarbe kann man im Tiefdruck Papiere bedrucken. Von diesen bedruckten Papieren kann man im Transfer-Verfahren Textilien aus Polyacrylnitril, z.B. Gewirke oder Samt, bei 190° unter 100 mbar und einem Anpressdruck des Mitläufers auf dem Transferpapier von etwa lg/cm2 bedrucken und erhält brillantrote Drucke von ausgezeichneter Echtheit.The printing ink obtained in this way can be used for gravure printing on papers. Of these printed papers, textiles made of polyacrylonitrile, for example knitted fabrics or velvet, can be printed in the transfer process at 190 ° under 100 mbar and a contact pressure of the follower on the transfer paper of approximately 1 g / cm 2, and brilliant red prints of excellent fastness are obtained.
