Abstract
The phenomenon of selective reflection of incident light by cholesteric type liquid crystals has been extensively investigated during the past decades and recently led to various applications. The most promising utilisations of liquid crystal sheets are in the field of thermograohy and infra-red technology. We have been involved in the conception of a new type of cholesteric mixtures which show nearly linear temperature-color dependence. The technological difficulties inherent to the realisation of several thin layers of microencapsulated liquid crystals layers on a soft polyester support are now solved. Sheets of large size which can be produced are expected to find applications in medicine, IR image convertion, industrial non-destructive testing.
