Red spray paints from different European suppliers were characterised to determine the discriminating power of a sequence of analysing techniques. A total of 51 red spray paints were analysed with the help of three techniques: (1) optical microscopy, (2) Fourier transform infrared spectrometry and (3) X-ray fluorescence. Infrared spectra were classified according to binder type, filler and pigment composition and a searchable spectral library was created. Due to the difference in the elemental composition of spray paints, a further discrimination was possible. The microscopic analysis was not taken into consideration for classification purposes. The structure of the substrate under a paint coating strongly affects the surface characteristics of this spray paint. Together with the spectral library, a database of information of spray paints was build.
对来自不同欧洲供应商的红色喷漆进行了特性分析，以确定一系列分析技术的鉴别能力。借助三种技术对总共51种红色喷漆进行了分析：（1）光学显微镜；（2）傅里叶变换红外光谱法；（3）X射线荧光分析法。红外光谱根据粘合剂类型、填料和颜料成分进行分类，并创建了一个可搜索的光谱库。由于喷漆元素组成的差异，进一步的鉴别成为可能。出于分类目的，未考虑微观分析。油漆涂层下基材的结构强烈影响这种喷漆的表面特性。连同光谱库一起，建立了一个喷漆信息数据库。
