摘要：

目的验证稳定的热敏可擦消失笔字迹显现方法。方法消褪后的字迹经自然存放、高温、紫外线处理,并常温放置一定时间的预处理后,运用低温、荧光、紫外线等显现方法显现消褪字迹,并采用紫外、红外光谱法、荧光光谱法分析可擦笔的油墨成分,对其显现机理进行分析。结果在预处理条件下,荧光法仅能显现部分品牌的可擦笔字迹;长波紫外线法显现效果较差;短波紫外线法、低温法可以清晰显现可擦笔字迹。结论在预处理条件下,低温法与短波紫外线法对热敏消褪字迹具有稳定的显现能力。

Objective To explore the stable method for the visible writing from thermosensitive erasable pen. Methods After the faded handwriting is naturally stored,treated with high temperature and ultraviolet light,and placed at normal temperature for a certain period of time,it is developed by low temperature,fluorescence,ultraviolet and other visualization methods. The ink composition of thermosensitive erasable pen is analyzed by ultraviolet,infrared spectroscopy,and fluorescence spectroscopy,and its manifestation mechanism is analyzed. Results Under the pretreatment conditions,the fluorescence method can only show the erasable writing of some brands. The long-wave ultraviolet method shows poor effect. The short-wave ultraviolet method and the low temperature method can clearly develop the erasable writing.Conclusion Under the pretreatment conditions,there is the stable ability to develop the fading writing from thermosensitive erasable pen with the short-wave ultraviolet method and the low temperature method.
