Title: Multilayer cholesteric thin film and its manufacture
Inventor: GREENFIELD SIMON
IPC: G02B5/30
Filed: 2000-07-03
Abstract: PROBLEM TO BE SOLVED: To obtain a multi-layered cholesteric thin film with which reflection wavelengths can be favorably selected, which is suitable for mass production, effective and cost-effective by changing a cholesteric helical pitch in adjacent layers by controlled transfer of a non-polymerizing chiral material present between individual layers. SOLUTION: This method for manufacturing a multi-layered cholesteric thin film comprises the steps of: coating a cholesteric material to form a cholesteric layer; polymerizing the material in the cholesteric layer; subsequently forming a second cholesteric layer, for example directly coating the cholesteric material to form the second layer having a different wavelength and polymerizing the material in the second layer. Further, an unpolymerized material present between adjacent layers, especially un-polymerized chiral material, is controllably transferred from the first polymerized layer to the second unpolymerized layer.  By controllably transferring the unpolymerized material, a helical pitch of the second layer can be changed depending on the degree of polymerization and the cross-linking density of the first layer while keeping the helical pitch of the first layer essentially unchanged.
