Abstract: Radiation curable compositions comprising at least one radiation curable oligomer responding to a structure (C)—(B)-(A)-[(B)(C)]x wherein (A) is the residue of one or more hydroxyl functional polyester having a molecular weight MN higher than 900, a TG and/or Tm of 5 less than 30° C., and which is obtained from an acid constituent comprising at least 75 mole % of saturated aliphatic polyacid and, optionally, 0 to 25 mole % of another polyacid and an alcohol constituent, (B) is the residue of one or more polyisocyanate, (C) is the residue of one or more ethylenically unsaturated hydroxyl compound, and x is from 0.5 to 10.

Abstract: Radiation curable compositions comprising at least one radiation curable oligomer obtained from the reaction of one or more carboxyl functional polyester (a) having a glass transition temperature TG and/or melting temperature Tm of less than 30° C., with (b1) one or more (meth)acrylated mono-epoxide, and/or (b2) one or more polyepoxide and one or more ?, ? unsaturated carboxylic acid.

Abstract: The invention relates to a process for preparing a coated metal sheet coil comprising the coating of the metal sheet with a curable composition comprising an (meth)acrylated oligomer which is the reaction product of a carboxyl functionalized polybutadiene comprising x equivalents of —COOH groups with (i) y equivalents of one or more (meth)acrylated monoepoxides or (ii) a mixture of z equivalents of one or more polyepoxides and at least (z?x) equivalents of an ?,?-unsaturated carboxylic acid; with z>x and y?x.
