Abstract

A barrier film, a document including a barrier coating, and a method for producing a document are described. A document includes a substrate, printed data on a surface of the substrate, and a barrier coating. The barrier coating is disposed between a portion of the printed data and a portion of an adhesive. The portion of the adhesive is disposed between a portion of a protective layer and a portion of the substrate.

First claim

What is claimed is:

1. A card or passport, comprising:
a card or passport substrate;
printed data on a surface of the card or passport substrate, wherein the printed data is produced using one of a dye and a pigment;
a barrier coating;
an adhesive layer comprising a thermoplastic with a glass transition temperature lower than about 150° C., wherein a portion of the barrier coating is disposed between a portion of the printed data and a portion of the adhesive layer, wherein the barrier coating prevents the adhesive layer from contacting the printed data on the card or passport substrate; and
a protective layer, wherein the portion of the adhesive layer is disposed between a portion of the protective layer and a portion of the card or passport substrate.

2. The card or passport according to claim 1 , further comprising:
a security feature layer disposed between the card or passport substrate and the protective layer.

3. The card or passport according to claim 2 , wherein the security feature layer includes an optically variable device.

4. The card or passport according to claim 1 , wherein the barrier coating comprises a mixture of acrylic resin and vinyl resin.

5. The card or passport according to claim 4 , wherein the weight percent of the acrylic resin is from about 5 percent to about 40 percent and the weight percent of the vinyl resin is from about 60 percent to about 95 percent.

6. The card or passport according to claim 1 , wherein the barrier coating has a dry weight from about 0.1 grams per square meter to about 35.0 grams per square meter.

7. The card or passport according to claim 1 , wherein a portion of the barrier coating is in direct contact with the card or passport substrate.

8. The card or passport according to claim 1 , wherein the barrier coating has a thickness between about 0.1 microns and about 35 microns.

9. A card or passport, comprising:
a card or passport substrate, wherein the card or passport substrate has first and second opposite surfaces;
printed data on the first surface of the card or passport substrate, wherein the printed data is produced using one of a dye and a pigment;
a barrier coating overlaying the printed data;
an adhesive layer overlaying the barrier coating, wherein the adhesive layer comprises an ultraviolet cured hot melt adhesive or a heat cured adhesive, wherein the barrier coating is disposed between the printed data and the adhesive layer and prevents the adhesive layer from contacting the printed data; and
a protective layer, wherein the adhesive layer is disposed between the protective layer and the barrier coating.

10. The card or passport or claim 9 , further comprising a security feature layer between the protective layer and the adhesive layer.

11. The card or passport or claim 1 , wherein the thermoplastic comprises polyurethane.
