PROCEDE DE REALISATION DE COUCHES MINCES STRUCTUREES EN 3D

摘要

The method for producing a stack of films provided with at least one 3D-structured pattern including providing a first mould having a textured front face including a first 3D pattern, depositing a first layer of the stack on the textured front face so as to cover the first 3D pattern by a continuous layer, the first layer having a first face in contact with the front face of the mould, removing the first mould so as to release the first face of the first layer having a second 3D pattern complementary to the first 3D pattern and depositing a second layer of the stack on the first face of the first layer so as to cover the second 3D pattern by a continuous layer.
