Abstract

La présente invention vise à améliorer la résistance à la stratification et la résistance au blocage de la matière imprimée obtenue par impression de films de résines, par exemple le poly(téréphtalate d'éthylène), le polypropylène et les nylons, avec une composition d'encre pour jet d'encre aqueuse. La présente invention concerne par conséquent un jeu d'encres comprenant : une composition d'apprêt aqueuse comprenant une résine acrylique et/ou une résine acétate de vinyle, un sel de calcium, et une polyoléfine chlorée ; et une composition d'encre pour jet d'encre aqueuse qui comprend une résine styrène/acrylique ayant une température de transition vitreuse (Tg) de -40 à -10 °C et une cire de polyéthylène.
