We studied ten alkyd artists' paints from the Griffin Alkyd, “fast drying oil colours” series (Winsor & Newton) in order to evaluate the effect of pigment–binder interactions on the stability of the alkyd resin. The literature on alkyd paints has focused above all on the characterization of the paints and their ageing processes using various techniques, however, to the best of our knowledge, research on pigment-resin interaction is still lacking
