Abstract
Abstract The urethane derivatives of acrylated epoxidized soybean oil, which is the reaction product of epoxidized soybean oil with acrylic acid or methacrylic acid, are produced by the reaction of acrylated epoxidized soybean oil with an organic isocyanate. They are useful alone, or in conjunction with a photosensitizer, and/or a pigment as inks and coatings. The compositions can be cured by radiation.
