摘　　要：两种隐色化合物在近紫外光区有吸收并分别发射红色和蓝色荧光。它们具有较高的荧光量子效率,可与适当的树脂配合制成隐色标记材料。通过吸收光谱、荧光光谱和反射光密度介绍了它们的隐色特性和显色表征。Two fluorescent compounds, shown absorptions in near ultraviolet region, can emit red and blue fluorescence respectively with high fluorescent quantum yields. The cryptic marking materials were prepared by adding these compounds in appropriate resins. Their cryptic character and colouration of cryptic mark were elucidated by the spectral behaviors and reflected optical density.
