Zusammenfassung:Coding flake or film including at least two chiral liquid crystal polymer (CLCP) layers with a first CLCP layer that has a first detectable parameter and a second CLCP layer including a second detectable parameter; at least one additional layer including a third detectable parameter, the at least one additional layer comprising a material that is not a chiral liquid crystal polymer; and wherein at least the third detectable parameter is different from each of the first detectable parameter and the second detectable parameter.
