Abstract
The cause of yellowing of oil-based paints has been investigated by analysi ng drying oils simultaneously by iodometry (to determine the degree of oxid ation) and by colorimetry. It was found that yellowing of drying oils can b e attributed to co-oxidation reactions of contaminants. Yellowing level is closely related to the extent of drying and appears to be unaffected by inc rease in temperature, the addition of driers, or linolenate content.
