Alkyd resins have been introduced in the 1930s as binders for paints. Their compatibility with many polymers and
the extremely wide formulating latitude made them suitable for the production of a very broad range of coating
materials. This includes do-it-yourself paints and varnishes for wood and metal, road marking paints, anticorrosive
paints, nitrocellulose lacquers, two-component isocyanate curing coatings, acid curing coatings, stoving enamels,
etc. Except for phthalic anhydride, being of petrochemical origin, the other raw materials used in the synthesis of the
alkyds are from biologically renewable sources. This, combined with their biological degradability, makes them
very interesting binders from an ecological point of view. Solvents which are used to reduce and adjust the paint
viscosity are the only concern with respect to the ecological aspects of the alkyds paints. In recent years, however,
we witness quite an activity in designing alkyd emulsions and high solids alkyds which can serve as binders for
