Abstract
A method of fabricating a strip thermometer comprising the steps of applying a plurality of cholesteric liquid crystal compositions exhibiting color changes over different temperature responsive ranges to a first substrate; coating a second substrate with an uncured solid film forming epoxy resin composition; partially curing the epoxy resin composition coating on the second substrate to a non-absorbing partially cured state in which the cholesteric liquid crystal compositions will not be absorbed by the epoxy resin composition; placing the first and second substrates together so that the partially cured epoxy resin composition overlies the cholesteric liquid crystal compositions; forcing the first and second substrates toward each other to cause the partially cured epoxy resin composition to flow around the cholesteric liquid crystal compositions and into contact with the first substrate; and subsequently, finishing the curing of the epoxy resin composition to bond the epoxy resin composition to the first substrate. The thermometer produced by this method is also disclosed.
