Abstract

A component involving a substrate, a layered structure arranged on the substrate, and a barrier layer arranged over the layered structure, wherein the barrier layer has the reaction product of an epoxy resin and a polymeric polyol.

Claims

1. A component comprising a substrate, a layered structure arranged on the substrate, and a barrier layer arranged over the layered structure, wherein the layered structure includes an optically or an electrically active film and wherein the barrier layer comprises the reaction product of a polymeric polyol which is polyvinyl butyral, and a curable resin.

2. The component of claim 1, wherein the barrier layer is located at least at one outer surface of the component.

3. The component of claim 1, wherein the barrier layer is impermeable and edge covering.

4. The component of claim 1, wherein the component further comprises a laminate structure with a cover and an intermediate adhesive layer that is arranged over the barrier layer.

5. The component of claim 4, wherein the cover comprises at least one plastic layer.

6. The component of claim 4, wherein the cover is a glass plate.

7. The component of claim 1, wherein the amount of polymeric polyol is more than 1% by weight of the curable resin.

8. The component of claim 1, wherein the curable resin is UV curable.

9. The component of claim 7, wherein the amount of polymeric polyol is in the range of from 1% to 30% by weight of the curable resin.
