    • Fatty (meth)acrylates having a %-EpO content of below 0.6, which are reaction products of epoxidized compounds selected from the group consisting of epoxidized fatty acid esters, epoxidized triglycerides and mixtures thereof, and acids selected from the group consisting of acrylic acid, methacrylic acid and mixtures thereof, wherein the %-EpO content of the epoxidized compound is above 6.4, wherein the epoxidized compound is an epoxidation product of fatty acid moieties having one or more carbon-carbon double bonds, wherein less than 20 mole % of the fatty acid moieties contain three or more carbon-carbon double bonds, and wherein greater than 60 mole % of the fatty acid moieties contain two carbon-carbon double bonds are useful as pigment dispersants. Pigment dispersant concentrates, aqueous pigment dispersions and methods of dispersing pigments with the fatty (meth)acrylates are described.
