Abstract: Dispersions of high molecular weight, essentially non-polymerizable vinyl resins in mixtures of radiation curable monofunctional and polyfunctional acrylyl monomers and/or oligomers. The dispersions are useful as coating and ink compositions.

Abstract: Tetraethylorthosilicate or tetraethoxyethylorthosilicate is employed as a low-toxicity diluent in radiation curable coating compositions containing acrylyl or methacrylyl functional oligomer. The orthosilicate compound imparts improved leveling and surface characteristics to said coating compositions.

Abstract: Radiation curable acrylated polyurethane is porduced by (a) producing an isocyanate-terminated intermediate by coreacting an organic diisocyanate with a combination of organic tri/tetraol and organic diol, said combination being chosen from polyester tri/tetraol-polyether diol and polyether tri/tetraol-polyester diol combinations; (b) reacting the isocyanate-terminated intermediate with an hydroxyacrylate such as 2-hydroxyethyl acrylate. Unexpectedly, the oligomer has desirably low viscosity, yet cures upon exposure to radiation to a coating having good physical properties.

Abstract: Compositions based on 2(N-alkylcarbamoyl) alkyl acrylate have been prepared which are useful as coatings and inks.

Abstract: The addition of a small amount of acrylic acid to a silica-containing radiation curable coating increases the flatting efficiency of the silica.

Abstract: Acrylyl-terminated urea-urethane compositions that are the reaction product of an organic polyisocyanate, a hydroxylamine and a hydroxyhydrocarbyl acrylate. These compositions can be used in the preparation of coatings and inks.

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.

Abstract: Compositions based on 2(N-alkylcarbamoyl.Iadd.oxy) .Iaddend.alkyl acrylate have been prepared which are useful as coatings and inks.
