Patent Images
1. A color shifting film comprising:
- a support;
a reflective stack disposed adjacent to the support;
wherein the reflective stack comprises an at least partially transparent spacer layer comprising a substituted acrylamide polymer disposed between a partially reflective first layer and a reflective second layer; and
an image;
wherein the acrylamide layer has a thickness sufficient to produce an interference color.

Abstract
A method for forming a color shifting film on a support, the film comprising a reflective stack disposed adjacent to the support and an image is disclosed. The reflective stack comprises an at least partially transparent spacer layer comprising a substituted acrylamide polymer disposed between a partially reflective first layer and a reflective second layer. The acrylamide layer has a thickness sufficient to produce an interference color.

18. A method for forming a color shifting film on a polymer support, which method comprises:
-
forming a reflective stack disposed adjacent to the support by; depositing a reflective or partially reflective first layer adjacent the support, depositing an at least partly transparent spacer layer comprising a substituted acrylamide polymer on the reflective first layer, depositing a partially reflective or reflective second layer on the spacer layer; and forming an image; wherein the reflective stack has a thickness sufficient to produce an interference color. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
