Abstract
Solvent-borne alkyd resin compositions are disclosed comprising a high-purity maleinized rosin anhydride. Substitution of the trifunctional acid component of the alkyd resin composition with this rosin anhydride permits a reduction in the viscosity of the resin without adversely affecting the physical properties of the cured film of the resin.
