Abstract: Compositions of an acrylated epoxidized soybean oil, which is the reaction product of epoxidized soybean oil with acrylic acid or methacrylic acid, and a photosensitizer are useful for coatings and inks; a pigment can optionally be present. The compositions can be cured by radiation.

Abstract: Lower alkanoate esters of alcohols are contacted in the vapor phase and at elevated temperatures with certain metal oxide catalysts to produce the aldehyde or ketone corresponding to said alcohol. Preferred catalysts include nickel oxide, zinc oxide and chromium oxide.

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. The derivatives are useful alone, or in conjunction with a photosensitizer, and/or a pigment as inks and coatings in the methods of this invention whereby they are cured by exposure to radiation.

Abstract: Method for coating or printing using as the coating or printing medium compositions of an acrylated epoxidized soybean oil, which is the reaction product of epoxidized soybean oil with acrylic acid or methacrylic acid, and a photosensitizer are useful for coatings and inks, and a pigment. The compositions can be cured by radiation.

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.

Abstract: Coating compositions are cured by initially treating them for a brief period with ionizing or non-ionizing radiation whereby they are partially cured and then completing the cure by a thermal treatment. This two-step process decreases the amount of volatiles escaping into the atmosphere and it also permits the use of compounds not useful in the past and allows significant improvement in film properties such as adhesion to metal. The initial radiation cure can be with electron beam, ultraviolet mercury lamp, plasma arc or other radiation means; the thermal cure is carried out by any heat means.
