Abstract

Provided is a gas barrier film having superior gas barrier properties even when an organic gas barrier layer is provided to the surface of a plastic film. The gas barrier film is provided with an organic gas barrier layer containing a 1,3,5-triazine derivative at least at one surface of the plastic film, and is characterized by the 1,3,5-triazine derivative having as a substituent group a group containing sulfur at position 2, 4, or 6.

First claim

The invention claimed is:

1. A gas barrier film comprising a plastic film and an organic gas barrier layer containing a 1,3,5-triazine derivative on at least one surface of the plastic film, wherein
the 1,3,5-triazine derivative has sulfur-containing groups as a substituent on 2, 4 and 6 positions, and
the organic gas barrier layer has a thickness of 200 nm or less.

2. The gas barrier film according to claim 1 , wherein the 1,3,5-triazine derivative is triazine trithiol.

3. The gas barrier film according to claim 2 , wherein the organic gas barrier layer has a thickness of 100 nm or more.

4. The gas barrier film according to claim 3 , wherein the organic gas barrier layer is formed on the plastic film by vacuum vapor deposition method.

5. The gas barrier film according to claim 2 , wherein the organic gas barrier layer is formed on the plastic film by vacuum vapor deposition method.

6. The gas barrier film according to claim 1 , wherein the organic gas barrier layer has a thickness of 100 nm or more.

7. The gas barrier film according to claim 6 , wherein the organic gas barrier layer is formed on the plastic film by vacuum vapor deposition method.

8. The gas barrier film according to claim 1 , wherein the organic gas barrier layer is formed on the plastic film by vacuum vapor deposition method.
