The present invention relates to a near-ultraviolet stimulated light-emitting compound, and more specifically relates to a fluorescent quinazolinone compound which is stimulated in the near ultraviolet region. The fluorescent quinazolinone compound according to the present invention is colourless in daylight but exhibits a high fluorescent intensity when irradiated with light in the near ultraviolet region. Also, the fluorescent quinazolinone compound can be easily used with printed and plastic moulded products since the compound not only has a high degree of light fastness and thermal stability but also high dispersibility.
本发明涉及一种近紫外激发发光化合物,更具体地说,涉及一种在近紫外区受激发的荧光
喹唑啉酮化合物。根据本发明的荧光
喹唑啉酮化合物在日光下是无色的,但在近紫外区的光照射下会显示出很高的荧光强度。此外,由于荧光
喹唑啉酮化合物不仅具有很高的耐光性和热稳定性,而且还具有很高的分散性,因此可以很容易地用于印刷品和塑料模具。
