ABSTRACT This invention relates to fatty acid modified alkyd resins and the use thereof in formulation of high solids interior and exterior paints capable of curing at ambient temperatures without the use of appreciable amounts of solvent. More specifically the invention relates to high solids alkyd coatings derived from fatty acid oil modified alkyd resins having low viscosities capable of forming finishes that have good physical characteris- tics such as high gloss, resistance to humidity, excellent adhe- sion and a good hardness. These oil modified alkyd resins have number average molecular weights of less than about 6,000 and are derived from the polymerization of drying oil fatty acids, dibasic aromatic acids, polyols, at least one unsaturated mono- carboxylic acid and an unsaturated monohydric alcohol.
