Excitation by select d bands of energy in the UV region did not alter fatigue characteristics of N-3-pyridyl sydnone. Filters composed of an inorganic semiconductor and an UV absorber were examined the UV film enhanced the reflectivity of the optical filter and the UV excitation caused a shift to shorter wavelengths of the reflection edge in the near IR and visible region. Composite filters wit UV absorber and sydnone showed limited response to UV excitation. Electrochromic dye studies are discussed a dihydropyridine was strongly thermochromic.
