The characteristics of a temperature sensitive paint (TSP) were investigated experimentally. The tested TSP was made of Eu(TTA)3 phosphor which is a chelate compound and PVB binder. The phosphor of the TSP coated on the one side surface of tested foil was excited by UV light. The fluorescent image was taken by a CCD color camera under the constant condition to process with digitizing the image, while the back surface temperature on the TSP coated foil was measured by using a radiation thermometer as the temperature on the fluorescence. The binder, the surface temperature, the concentration of phosphor, the paint film thickness and UV light intensity were changed in the range of PVB300-1000, 15-90℃, 5-50 wt% and 3-12 μm and 50-350 μW/cm^2, respectively. As the result, these parametric effects on the temperature dependency of the TSP were found out and the stable performance of the TSP made of PVB300 binder was confirmed.
