在紫外光照射下，通过对蓝色圆珠笔字迹色痕ＦＴ－ＩＲ显微光谱的研究，发现溶剂挥 发迅速；其次是环氧树脂的聚合、交联；三苯甲烷染料的分解比较缓慢；而醇酸树脂相对稳定。 该研究为字迹色痕的进一步分辨提供了新方法，同时为字迹色痕的“年龄”推断奠定了基础。 选用相关峰的相对峰高比来描述这一变化，并进行曲线拟合，消除了国笔力不同而引起的油 墨流出量不同造成的误差，这在实际工作中是很有意义的。
Under UV irradiation, through the FT-IR microscopy of the blue ballpoint pen, it was found that the solvent volatilized rapidly, followed by the polymerization and crosslinking of the epoxy resin, and the decomposition of the triphenylmethane dye was relatively slow. However, Acid resin is relatively stable. The study provides a new method for further distinguishing between handwriting marks and at the same time laying the foundation for the “age” estimation of handwriting marks. The relative peak-to-peak ratio of the correlation peak is used to describe this change, and the curve fitting is performed to eliminate the errors caused by the different ink outflows caused by the differences in the country pen force, which is very meaningful in practical work.
