摘　　要：建立利用红外光谱仪检验无碳复写纸的分析方法。利用傅立叶变换红外光谱仪,对收集到的常用的60个不同使用地、不同单位使用的无碳复写纸样品进行分析检验。依据样品的红外光谱图对无碳复写纸的显色层成分进行表征,根据样品谱图的差异进行区分检验。该检验方法准确可靠、重现性好,可用于区分检验无碳复写纸物证。Objective was to establish a method for the discrimination of carbonless copy paper by FT-IR. With Fourier transform of infrared spectroscopy, 60 samples of carbonless paper from different using locations and users were discriminated. Result was according the spectra of sample, the ingredients in CB layer were characterized and the samples were discriminated. Conclusion was that this test method has the advantages of good accuracy and repeatability, and can be used for the discrimination of material evidence of carbonless copy paper.
