We propose ATR-FTIR spectroscopy for the characterization of the spectral changes in alkyd resin from the
Griffin Alkyd Fast Drying Oil Colour range (Winsor & Newton), occurring over 550 days (18 months) of
natural ageing and over six months of artificial ageing under an acetic acid atmosphere. Acetic acid is
one of the atmospheric pollutants found inside museums in concentrations that can have a significant
effect on the works exhibited
