The influence of UV light and temperature on poly(methylmethacrylate) (PMMA) and poly(vinylchloride) (PVC) films, doped with 2[(1,3,3-trimethylindoline-2(1H)-yliden)propen-1-yl]-3,3-dimethylindolino[1,2-b]-oxazolidine has been investigated. The radiation-induced colour was analyzed spectrophotometrically at the maximum of the absorption peak at 560 nm. The effect of the temperature on unirradiated and irradiated films was studied. The results demonstrate a strong photochromic and a weak thermochromic behaviour of the PMMA and PVC films. The relationship of photocolouration-thermal decolouration is discussed based on the spectral results reported here.
