摘要： PROBLEM TO BE SOLVED: To diagnose highly accurately the deterioration degree of a measuring object by fluorescence measurement, and to diagnose nondestructively the deterioration degree of the measuring object by a simple device for performing the fluorescence measurement.
SOLUTION: The fluorescence measurement is evaluated by a variation of the difference or the ratio of the fluorescence intensity between two wavelengths, and thereby the deterioration degree of the measuring object can be diagnosed highly accurately. As the simple device for performing the fluorescence measurement, an ultraviolet irradiation lamp such as a xenon lamp is used for excitation light, and a small-sized spectroscope is used for a fluorescence detector, and the fluorescence intensity of the measuring object is measured. Thus, the deterioration degree can be diagnosed nondestructively.

The epoxy resin of formula I can be obtained e.g. by reacting a diamine compound of formula II with epichlorohydrin by a known method. It is preferable that an epoxy resin composition containing the epoxy resin gives a thermally cured product having a glass transition temperature of >=175 deg.C and a flexural strain of 3.0-5.0. The composition preferably further contains an N-substituted unsaturated imide compound.
