ABSTRACT:
A liquid crystal film laminate embodies an indicator component and a supportive and protective component removable from the indicator component to provide maximum flexibility and minimum mass in the resulting indicating article. The indicator component includes a liquid crystal film and may include a protective layer and/or an adhesive layer. The film has an outer surface which forms one of two opposite side surfaces on the indicator component. The supportive and protective component includes two release surfaces provided by at least one release sheet, such release surfaces separably contacting respective ones of the indicator component side surfaces in covering relation thereto, for removably supporting and protecting the indicator component. The outer surface of the film thereby is exposed to unobstructed view upon removal of the supportive and protective component, for maximum clarity of the indication given by the film. The maximum total thickness of the indicator component preferably is about 4 mils.
