Beschreibung
Zusammenfassung:	An ultraviolet radiation absorbent for thermoplastic polymer materials such as polyethylene terephthalate or polycarbonate contains cyclic imino ester compound of a specified structure in an amount of over 99.5 weight % and less than 100 weight %, having the melt beginning temperature obtained by melting point measurement in differential thermal analysis within the range of 300-310 DEG C and/or the weight loss beginning temperature obtained by thermogravimetric measurement within the range of 270-305 DEG C.
