Abstract
Elemental analysis of solid blue paint chips for a truck was carried out by scanning electron microscopy/energy dispersive X-ray analysis (SEM/EDX).
We could detect 6 elements (Cl, Ti, Fe, Cu, Br and Ba) used for color pigments such as phthalocyanine blue (chlorinated copper phthalocyanine) and phthalocyanine green (brominated copper phthalocyanine) from the paint chips collected.
It was found that the characteristic patterns, elements and the X-ray intensity ratios of these elements could be useful to discriminate solid blue paints.
Elemental analysis by SEM/EDX allowed us to discriminate solid blue paints for a truck, even if the sample was a very tiny smeared one.
