Process for the preparation of a multilayer structure comprising a substrate, a crystalline organic barrier layer, and a printed pattern; and products obtained therefrom

摘要

The invention provides a process for making a multilayer structure with a printed pattern by
a) providing a film substrate having a crystalline organic compound layer, wherein the substrate optionally has a metal or metaloxide layer between the film substrate and the organic compound layer;
b) applying a printed pattern via a plurality of printing rolls wherein the following steps are performed:
b1) optionally, applying as a first layer a primer over the whole surface,
b2) applying one or more ink layers on the film to obtain a printed pattern, and
b3) optionally, applying a cover varnish layer;
to obtain a film substrate with a crystalline organic compound layer and a printed pattern. The invention further relates to a laminate comprising a multilayer structure and a plastic film; the laminate preferably comprises a primer substantially covering the whole surface of the organic compound layer, on which primer the print is present.
