Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung von Transferpapier für Thermo sublimationsdruck-Prozesse, ein Transferpapier für Thermosublimationsdruck-Prozesse sowie ein Verfahren zum Bedrucken von Textilien. Das Verfahren zur Herstellung von Transferpapier umfasst einen Verfahrens schritt zur Beschichtung zumindest einer Oberfläche einer Papierbahn durch Aufträgen einer wässrigen Lösung eines α-(1,3→glucan)-Polymers, welches a-(1,3 ->glucan)-Polymer einen Substitutionsgrad durch kationische Gruppen von 0,2 bis 0,8 mol/mol aufweist, sowie einen Verfahrensschritt zur Nachtrocknung der beschichteten Papierbahn. Das Transferpapier weist ein Papiersubstrat auf, wobei zumindest eine Oberfläche des Papiersubstrats mit einer Beschichtung versehen ist, welche Beschichtung zumindest überwiegend aus einem kationisch modifizierten α-(1,3→glucan)-Polymer mit einem Substitutionsgrad durch kationische Gruppen von 0,2 bis 0,8 mol/mol besteht.
(EN)
The invention relates to a method for producing transfer paper for dye sublimation printing processes, a transfer paper for dye sublimation printing processes and a method for printing on textiles. The method for producing transfer paper comprises a method step for coating at least one surface of a paper web by applying an aqueous solution of an α-(1,3→glucan) polymer, which α-(1,3→glucan) polymer has a degree of substitution by cationic groups of 0.2-0.8 mol/mol, and a method step for postdrying the coated paper web. The transfer paper has a paper substrate, at least one surface of said paper substrate being provided with a coating which consists at least predominantly of a cationically modified α-(1,3→glucan) polymer having a degree of substitution by cationic groups of 0.2-0.8 mol/mol.

L'invention concerne un procédé de fabrication de papier transfert pour des procédés d'impression par sublimation, un papier transfert pour des procédés d'impression par sublimation et un procédé d'impression sur textiles. Le procédé de production de papier transfert comprend une étape de procédé consistant à revêtir au moins une surface d'une feuille de papier continue par application d'une solution aqueuse d'un polymère α-(1,3→glucan), lequel polymère α-(1,3→glucan) présente un degré de substitution par des groupes cationiques de 0,2 à 0,8 mol/mol, et une étape de procédé de post-séchage de la feuille de papier continue revêtue. Le papier transfert comporte un substrat de papier, au moins une surface dudit substrat de papier étant pourvue d'un revêtement constitué au moins principalement d'un polymère α-(1,3→glucan) à modification cationique dont le degré de substitution par des groupes cationiques est de 0,2 à 0,8 mol/mol.
