ABSTRACT:
Disclosed is an amorphous organic thin-film element containing dye molecules with .SIGMA..DELTA.Str,m (J/(K.kmol))/Mw of 60 or less, assuming that the molecular weight is Mw and the sum total of an entropy change of melting and entropy changes of transition from a glass transition point to a melting point is .SIGMA..DELTA.Str,m (J/(K.kmol)), and having a high heat resistance and a high stability over long periods of time.
