Abstract
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 colorless 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 molded products since the compound not only has a high degree of light fastness and thermal stability but also high dispersibility.
