Title (EN) INKJET PRINTING
(FR) IMPRESSION À JET D'ENCRE
Abstract:
(EN) The present disclosure relates to an Inkjet printing process that comprises inkjet printing an inkjet ink composition onto a substrate to form a printed inkjet ink layer. The inkjet ink composition comprises a colorant, a curable polyurethane dispersion, a photoinitiator and water, wherein the amount of curable polyurethane dispersed in the inkjet ink composition is 0.1 to 30 weight %. A radiation-curable overcoat composition is applied over the printed inkjet ink layer as an overcoat layer. The overcoat composition comprises a curable polyurethane dispersion, a photoinitiator and water. The printed inkjet ink layer is then cured on the substrate by exposing both the overcoat Iayer and inkjet ink layer on the substrate to radiation.
(FR) La présente invention concerne un procédé d'impression à jet d'encre qui comprend l'impression à jet d'encre d'une composition d'encre pour jet d'encre sur un substrat afin de former une couche d'encre à jet d'encre imprimée. La composition d'encre pour jet d'encre comprend un colorant, une dispersion de polyuréthane durcissable, un photo-initiateur et de l'eau, la quantité de polyuréthane durcissable dispersée dans la composition d'encre pour jet d'encre étant de 0,1 à 30 % en poids. Une composition de finition durcissable par rayonnement est appliquée sur la couche d'encre à jet d'encre imprimée en tant que couche de finition. La composition de finition comprend une dispersion de polyuréthane durcissable, un photo-initiateur et de l'eau. La couche d'encre à jet d'encre imprimée est ensuite durcie sur le substrat par exposition de la couche d'encre de finition et de la couche d'encre à jet d'encre sur le substrat à un rayonnement.
