ABSTRACT:
A method for generating a 3-dimensional effect involves providing at least one first image layer of a chiral liquid crystal material, and at least one second image layer of a chiral liquid crystal material, wherein one of the first and second image layers reflects right-handed circularly polarised light and the other reflects left-handed circularly polarised light, is suitable creating a 3-dimensional image that can be used for decorative and security applications.
