摘要：
The present invention relates to novel cholesteric layered materials having the layer sequence A1/B/A2, where A1 and A2 are identical or different and each comprise at least one cholesteric layer, and B is at least one interlayer separating the layers A1 and A2 from one another, wherein layer B is an adhesive layer; cholesteric multilayered pigments which can be produced therefrom; a process for their production, and their use.
