Abstract

A number of metal complexes were examined as potential antiyellowing additives for linseed oil-based coatings. Yellowing was measured as the rate of increase of the absorbance at 400 nm of solutions of 20% linseed oil in toluene. Most metal complexes increased the yellowing rate, but 1,1-bis(diphenylphosphino)ferrocene retarded the rate by 50% over a wide concentration range, and some complexes caused nonlinear changes that might make them useful as additives.
