Study of the influencing effect of pigments on the photoageing of terpenoid resins used as pictorial media
Popis výsledku v původním jazyce
Terpenoid resins have been mainly used as components of pictorial varnishes and binding media from ancient times. In such latest instances, the resin is mixed with pigments affecting its physical and chemical properties. A new procedure based on gas chromatography?mass spectrometry (GC/MS) has been applied, in this work, in combination with Fourier transform infrared spectroscopy (FTIR), with the aim of determining the changes undergone by di- and triterpenoid resins employed as components of binding media. The GC/MS method is based on the derivatisation of these resins using trimethylsilylimidazol. Characterization of the main components of the di- and triterpenoid fractions and their oxidised products, occurring in the diterpenoid resin colophony anda triterpenoid Mexical copal (Bursera cuneata (Schl) Engl.), has been achieved. Artificially photoaged specimens of pure resin and binary systems pigment + resin prepared as thin films using lead white, ochre yellow, umber raw and verdig
