“…1-C, show the intense absorption band at 1730 cm −1 (carbonyl stretching), and the less intense peaks at 2982 cm −1 and 2952 cm −1 (CH stretching), and the signals at 1446 cm −1 and 1381 cm −1 (CH bending) are consistent with the presence of an acrylic binder [31]. In sample LI 29, the signals at 3690 cm −1 , 3620 cm −1 and 970 cm −1 are due to the inorganic ultramarine blue pigment in association with kaolinite [34], while, in sample LI 7, signals at 1389 cm −1 , 1305 cm −1 , 1155 cm −1 and 930 cm −1 are characteristic of the phthalocyanine dye [35]. As expected, the characteristic IR absorptions of Cadmium Red, which is the pigment of sample LI 108, are not detected in the investigated spectral range [35].…”

The presence of a cadmium-based pigment was confirmed by SEM-EDX analysis on sample LI 108 revealing the presence of cadmium, sulfur and selenium.…”

“…Phthalocyanines are indeed the most diffuse blue and green synthetic organic pigments. The presence of Cu-phthalocyanine, detected also in sample 17, is assessed by the peak at about 1500 cm −1 due to aromatic groups vibrations, as well as by the signals at 748 cm −1 and 723 cm −1 [41].…”

Graffiti removal from monuments, such as statues or architecture, is becoming a priority for conservators and restorers. This operation is further complicated when the vandalism is carried out on surfaces that should be preserved, as in the case of writings or tags on historical wall paintings, or even on modern or contemporary pieces of street art. Several methods exist for graffiti removal, which include chemical, physical or biological approaches. However, traditional methodologies, such as the use of neat organic solvents, are often unsuitable. Moreover, due to the great variability of brands and formulation of commercial paints, a thorough study of materials used for graffiti and a deep knowledge of their behavior when exposed to cleaning media is currently lacking. In this contribution, we report a systematic laboratory survey on 17 different spray-can paints available on the market and commonly used for graffiti and vandalism in the Mexican area. These paints were analyzed by means of ATR FT-IR spectroscopy to characterize their composition. Several solvents, having different nature and polarity, were then used to remove the paints from glass slides. On the basis of these results, two different amphiphile-based nanostructured fluids, which present several advantages with respect to traditional cleaning methodologies, were formulated and tested on the same paint samples. Finally, the two nanostructured cleaning systems were used for the removal of vandalistic graffiti from stones decorated with red pre-Hispanic paintings in the archeological site of Ba' Cuana, Asunciòn Ixtalpetec, Oaxaca, Mexico.
