PROCESS FOR THE PREPARATION OF A MULTILAYER STRUCTURE COMPRISING A SUBSTRATE, A CRYSTALLINE ORGANIC BARRIER LAYER, AND A PRINTED PATTERN; AND PRODUCTS OBTAINED

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.
