Dyes are among the most significant components in works of art and archaeological findings. In the scientific examination of historical artefacts, the identification of natural dyestuffs is a challenging task, due to the complexity of their chemical composition and the possible presence of mixtures of chromophores and degradation products. For this reason, in the last few decades, new analytical procedures and techniques have been developed and improved for the characterisation of organic dyes and their identification in micro samples. This review looks at the chemical composition of natural organic dyeing materials used in the field of the Cultural Heritage and focuses on several analytical methods based on spectrometric and chromatographic techniques which have contributed to the study of organic dyes in works of art and archaeological findings.

Abstract
Dyes are among the most significant components in works of art and archaeological findings. In the scientific examination of historical artefacts, the identification of natural dyestuffs is a challenging task, due to the complexity of their chemical composition and the possible presence of mixtures of chromophores and degradation products. For this reason, in the last few decades, new analytical procedures and techniques have been developed and improved for the characterisation of organic dyes and their identification in micro samples. This review looks at the chemical composition of natural organic dyeing materials used in the field of the Cultural Heritage and focuses on several analytical methods based on spectrometric and chromatographic techniques which have contributed to the study of organic dyes in works of art and archaeological findings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
