Patent ID: 7192478

Claim:
A method comprising: (a) providing a pigment; (b) providing a fatty (meth)acrylate having an epoxide value of below 0.6, wherein the fatty (meth)acrylate is a product of a process comprising reacting an epoxidized compound selected from the group consisting of epoxidized fatty acid esters, epoxidized triglycerides and mixtures thereof, with an acid selected from the group consisting of acrylic acid, methacrylic acid and mixtures thereof, wherein the epoxide value 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; and (c) combining the pigment and the fatty (meth)acrylate in a liquid carrier medium.
