A COMPOSITE MATERIAL COMPRISING A SUBSTRATE WITH A BARRIER LAYER APPLIED THEREON, AND PROCESS FOR MANUFACTURING THE SAME

摘要

1. A composite material comprising a substrate and a layer on the substrate, wherein the layer comprises a triazine compound selected from the group consisting of melamine, ammeline, ammelide, cyanuric acid, 2-ureidomelamine, melam, melem, melon and melamine salts, or a combination thereof. 2. A composite material according to claim 1, wherein the layer comprises a triazine compound selected from melamine, melam, melem, melon or a combination thereof. 3. A composite material according to claim 1 or claim 2, wherein the triazine compound is melamine. 4. A composite material according to any one of claims 1 to 3, wherein the composite material has another layer on top of the layer comprising the triazine compound. 5. A process for the manufacture of a composite material comprising a substrate and a layer on the substrate in which the layer is vapour-deposited, wherein the layer that is vapour-deposited comprises a triazine compound selected from melamine, melam, melem, melon or a combination thereof. 6. A process according to claim 5, wherein the layer that is vapour-deposited comprises melamine. 7. A process according to claim 5 or 6, wherein the temperature difference between the vaporizing triazine compound and the substrate onto which the triazine compound is vapour deposited is greater than 100 degree C.
