Abstract
Compositions of urethane derivatives of acrylated epoxidized soybean oil, which are the reaction products of an organic isocyanate with the reaction product of epoxidized soybean oil with acrylic acid or methacrylic acid, and an acrylyl compound are useful as coatings and inks; photosensitizers and/or pigments can optionally be present. The compositions can be cured by radiation.
