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 α,β-unsaturated carboxylic acid; with z>x and y≧x.
