Multivariate analysis studies of the ageing effect for artist's oil paints containing modern organic pigments1. (12th March 2014) - Sano, Naoko
Abstract This work demonstrates the potential of surface analysis techniques to contribute to a better understanding for art conservators of the degradation of modern paints. The model paints we select are modern synthetic organic pigments in linseed oil. The results, using a combination of X‐ray photoelectron spectroscopy data and multivariate analysis, show good agreement with previous studies using different techniques such as pyrolysis gas chromatography mass spectrometry regarding the ageing effect in oil paints. In addition, we demonstrate that two different modern organic pigments produce a different oxidation status of the linseed oil in the paint matrix. Copyright © 2014 John Wiley & Sons, Ltd.
