Abstract

The present invention relates to an holographic structure comprising an organic solvent based embossed layer, a metallic layer located onto the embossed layer, and an organic solvent based printing ink layer characterised in that the printing ink layer and the metallic layer are solely separated by a water solvent based primer.

Claims

1. A process of making a holographic structure comprising:

producing a pattern on an organic solvent based embossed layer to exhibit a holographic effect;

applying a metallic layer onto said embossed layer; and

applying a primer and a printing ink layer onto said metallic layer such that said printing layer and said metallic layer are solely separated by said primer,

wherein said primer is water solvent based and wherein said printing ink layer is organic solvent based.

2. The process of claim 1 further comprising the step of forming said embossed layer from a lacquer and applying said embossed layer to a thermoplastic film.

3. The process of claim 2 wherein said thermoplastic film is a polyester film.

4. The process of claim 2 further comprising the step of laminating said thermoplastic film to a second thermoplastic film.

5. The process of claim 1 wherein said metallic layer is an aluminum layer.

6. The process of claim 1 wherein said organic solvent based embossed layer is an acrylic based lacquer.

7. The process of claim 1 wherein said ink layer comprises a colored ink and a white ink, said colored ink comprising ethanol as an organic solvent and said white ink comprising ethyl-acetate as an organic solvent.

8. The process of claim 1 wherein said water solvent based primer comprises acrylic compounds.

9. A package made from a film laminate having a holographic structure made according to the process of claim 1.
