Title
(EN) PRINTING SYSTEMS AND METHODS INCLUDING MULTILAYER FILMS
(FR) SYSTÈMES ET PROCÉDÉS D'IMPRESSION COMPRENANT DES FILMS MULTICOUCHES
Abstract
(EN)
Embodiments of the present disclosure are directed to printing systems and methods that may include an ink composition including electrically charged ink particles dispersed in a hydrocarbon liquid and a multilayer film. The multilayer film may include a polymeric core layer; and one or more printing layers adjacent to the polymeric core layer. The one or more printing layers may include at least 50 wt.% of an ethylene vinyl acetate copolymer having acid and acrylate functional groups. The ethylene vinyl acetate copolymer having acid and acrylate functional groups may include from 0.5 wt.% to 4 wt.% methacrylic or acrylic acid; from 0.5 wt.% to 4 wt.% acrylate, from 7 wt.% to 40 wt.% vinyl acetate; and the balance ethylene, based on the total weight of the ethylene vinyl acetate copolymer having acid and acrylate functional groups.

Des modes de réalisation de la présente invention concernent des systèmes et des procédés d'impression qui peuvent comprendre une composition d'encre comprenant des particules d'encre chargées électriquement dispersées dans un liquide hydrocarboné et un film multicouche. Le film multicouche peut comprendre une couche centrale polymère ; et une ou plusieurs couches d'impression adjacentes à la couche centrale polymère. La ou les couches d'impression peuvent comprendre au moins 50 % en poids d'un copolymère d'éthylène-acétate de vinyle ayant des groupes fonctionnels acide et acrylate. Le copolymère d'éthylène-acétate de vinyle ayant des groupes fonctionnels acide et acrylate peut comprendre de 0,5 % en poids à 4 % en poids d'acide méthacrylique ou d'acide acrylique ; de 0,5 % en poids à 4 % en poids d'acrylate, de 7 % en poids à 40 % en poids d'acétate de vinyle ; et de l'éthylène pour le reste, sur la base du poids total du copolymère d'éthylène-acétate de vinyle ayant des groupes fonctionnels acide et acrylate.
