A film device to visualize UV irradiation was successfully fabricated by an agarose solid film containing Fluoran dye, acid generator N -tosyloxyphthalimide and 2-propanol medium, and the mechanism and kinetics of this system were investigated. The reactions involving: (1) acid generation from N -tosyloxyphthalimide by UV irradiation, (2) acid generation from N -tosyloxyphthalimide by chemical amplitude reaction, (3) coloring reaction of Fluoran dye by acid were analyzed by changing the Fluoran dye concentration. The concentration of the colored Fluoran dye was determined by the absorbance at 520 nm appearing by UV irradiation. The kinetic constants of the three reactions were estimated by solving the differential equations by the formation of the colored Fluoran dye with changing the parameters based on a least square method. The result was in accordance with the experimental results to give reaction rate constants of the processes.
