Abstract

Multilayer graphic films having high opacity are described. The films may exhibit long term removability. In certain versions, the films are well suited for use as vehicle wrapping films. Also described are methods of using the films and methods for manufacturing the films.

First claim

What is claimed is:

1. A multilayer film comprising:
a clear adhesive layer;
a tie coat layer;
a white layer;
a color layer; and
a clear layer;
wherein the tie coat layer is disposed immediately adjacent to and between the clear adhesive layer and the white layer.

2. The multilayer film of claim 1 wherein the white layer is immediately adjacent to the color layer.

3. The multilayer film of claim 1 wherein the color layer is immediately adjacent to the clear layer.

4. The multilayer film of claim 1 wherein the tie coat layer is gray.

5. The multilayer film of claim 1 wherein the clear adhesive layer has a thickness in a range of from 0.2 mil to 2.0 mil.

6. The multilayer film of claim 1 wherein the tie coat layer has a thickness in a range of from 0.1 mil to 1.4 mil.

7. The multilayer film of claim 1 wherein the white layer has a thickness in a range of from 1.0 mil to 2.0 mil.

8. The multilayer film of claim 1 wherein the color layer has a thickness in a range of from 1.0 mil to 2.5 mil.

9. The multilayer film of claim 1 wherein the clear layer has a thickness in a range of from 0.2 mil to 1.5 mil.

10. The multilayer film of claim 1 wherein the tie coat layer is gray, the thickness of the clear adhesive layer is about 1.4 mil, the thickness of the gray tie coat layer is about 0.2 mil, the thickness of the white vinyl layer is about 1.5 mil, the thickness of the color layer is about 1.5 mil, and the thickness of the clear vinyl layer is about 1.2 mil.

11. A multilayer film comprising:
a clear adhesive layer;
a tie coat layer;
a color layer; and
a clear layer;
wherein the tie coat layer is disposed immediately adjacent to and between the clear adhesive layer and the color layer.

12. The multilayer film of claim 11 wherein the tie coat layer is white.

13. The multilayer film of claim 11 wherein the clear adhesive layer has a thickness in a range of from 0.2 mil to 2.0 mil.

14. The multilayer film of claim 11 wherein the tie coat layer has a thickness in a range of from 0.1 mil to 1.4 mil.

15. The multilayer film of claim 11 wherein the color layer has a thickness in a range of from 1.0 mil to 2.5 mil.

16. The multilayer film of claim 11 wherein the clear layer has a thickness in a range of from 0.2 mil to 1.5 mil.

17. The multilayer film of claim 11 wherein the color layer is immediately adjacent to the clear layer.

18. The multilayer film of claim 11 wherein the tie coat layer is white and the thickness of the clear adhesive layer is about 1.4 mil, the thickness of the white tie coat layer is about 0.8 mil, the thickness of the color vinyl layer is about 2.0 mil, the thickness of the clear layer is about 1.2 mil.
