Abstract: A new process for recovering high purity natamycin from fermentation broth containing natamycin comprises the steps of adjusting the pH of the broth to above about 10 and adding an amount of a water-miscible solvent, such as isopropanol, sufficient to dissolve the natamycin in the broth, followed by removing insoluble solids from the pH-adjusted broth, followed by lowering the pH of the broth to a level sufficient to precipitate the natamycin, and removing the natamycin from the broth.

Abstract: Compositions of amine derivatives of acrylated epoxidized soybean oil, which are the reaction products of an organic amine with the reaction product of epoxidized soybean oil with acrylic acid or methacrylic acid, and an acrylyl compound which are useful as coatings and inks are cured by radiation. The compositions can also contain photosensitizers and/or pigments.

Abstract: The amine 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 amine and cured by radiation. They are useful alone, or in conjunction with a photosensitizer, and/or a pigment as inks and coatings.

Abstract: The dissolution of certain low molecular weight vinyl resins in radiation curable compositions of one or more polyfunctional polymerizable reactive solvent and, optionally, one or more monofunctional reactive solvent yields compositions having better adhesion to metals than is obtained with the same composition without the vinyl resins and with better stain and abrasion resistance than could be obtained with the vinyl resins alone. The low molecular weight vinyl polymer is preferably a vinyl acetate polymer having an inherent viscosity below about 0.25 and a glass transition temperature from about 25.degree.C. to about 55.degree.C.BACKGROUND OF THE INVENTIONEver-increasing restrictions on the amounts and types of volatiles permitted to escape into the atmosphere from coating and ink compositions have prompted considerable efforts to develop liquid compositions having a minimal amount of volatile components.

Abstract: Compositions of amine derivatives of acrylated epoxidized soybean oil, which are the reaction products of an organic amine 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.
