进一步研究了合成有机颜料在UVB人工照射后Acrylem AC 33（一种水性丙烯酸粘合剂）降解中的影响，将研究扩展到其他颜料类别（蒽醌类、酞菁类、二酮基吡咯并吡咯类）以及先前研究的偶氮颜料。与衰减反射和透射模式的傅里叶变换红外光谱和核磁共振光谱一起，拉曼光谱也用于观察颜料的老化过程。在这项研究中还观察到了与不同颜料的存在相关的特定效应;此外，拉曼光谱突出了对某些颜料的光致效应，这可能有助于文化遗产诊断，特别是街头艺术品。(C)2018爱思唯尔有限公司版权所有。
The influence of Synthetic Organic Pigments in the degradation of Acrylem AC 33, a waterborne acrylic binder, after UVB-artificial exposure was furtherly investigated, extending the study to other pigments classes (anthraquinones, phthalocyanines, diketo-pyrrolo-pyrroles) in addition to previously studied azopigments. Together with Fourier Transform Infrared, both in Attenuated Reflectance and Transmission mode, and Nuclear Magnetic Resonance spectroscopies, Raman spectroscopy was also used to observe ageing processes that pigments are subjected to. Specific effects, relative to the presence of different pigments, have been observed also in this study; moreover, Raman spectroscopy highlighted photoinduced effects on some pigments, which could result useful in Cultural Heritage diagnostics, especially for street artworks.
