Title
(EN) INKJET PRINTING ON POLYCARBONATE SUBSTRATES
(FR) IMPRESSION À JET D'ENCRE SUR DES SUBSTRATS DE POLYCARBONATE
Abstract
(EN)
The invention relates to a method for inkjet printing radiation-curable ink, such as UV- curable ink, onto a polycarbonate substrate that is treated with a treating fluid being a homogeneous liquid at a temperature between 15 and 35°C, comprising at least 1 wt% of one or more cyclic ketones being liquid at a temperature between 15 and 35°C, based on the weight of the homogeneous liquid phase, wherein the remainder of the treating fluid consists of a diluent chosen from the group consisting of diacetone alcohol, n-hexane, n-heptane and n- octane.The invention further relates to inkjet printed polycarbonate substrates obtainable by said method.
(FR)
L'invention concerne un procédé d'impression à jet d'encre d'une encre durcissable par rayonnement, telle qu'une encre durcissable aux UV, sur un substrat de polycarbonate qui est traité avec un fluide de traitement qui est un liquide homogène à une température comprise entre 15 et 35 °C, comprenant au moins 1 % en poids d'une ou plusieurs cétones cycliques qui sont liquides à une température comprise entre 15 et 35 °C, sur la base du poids de la phase liquide homogène, le reste du fluide de traitement étant constitué d'un diluant choisi dans le groupe constitué d'alcool de diacétone, n-hexane, n-heptane et n--octane. L'invention concerne en outre des substrats de polycarbonate imprimés par jet d'encre pouvant être obtenus par ledit procédé.
