内容記述 | Visible reflection spectrometry is a useful non-destructive method to analyze organic dyestuffs and some pigments containing no elements heavier than potassium, which can be detected by X-ray fluorescence method (XRF). However, reflection spectra can shift easily and be altered due to various causes such as light scattering, possibly leading to misunderstanding of results. In such a case, acquiring their second derivative spectra may make analysis more accurate because these spectra can enhance the peaks of original spectra, which are characteristic for each color material. Moreover, second derivative spectra are independent of the background if it is linear against wavelength. In this study, the application of second derivative spectra as additional data for identifying three blue color materials, indigo, prussian blue and ultramarine blue, which have been used in Japan since the late Edo era, was investigated. Calculated second derivative spectra of these three materials from measured visible reflection spectra showed that prussian blue spectrum was distinguishable from the other two. However, the two are quite similar. Therefore, second derivative spectra can identify “russian blue” or “indigo or ultramarine blue” with high accuracy. Identifying either one of the latter two is a future topic. |
