Abstract of the Disclosure Disclosed is an ungelled radiation curable resin which is a reaction product of (a) a polyfunctional hydroxyl containing carboxylic acid having a molecular weight less than or equal to 1,000 and having a total functionality of equal to or greater than 3; (b) an organic hydroxyl-functional compound; and (c) an alpha,beta-ethylenically unsaturated carboxylic acid. Also disclosed is a radiation curable composition containing the radiation curable resin in combination with a polymer having a glass transition temperature equal to or higher than minus 17 degrees Celsius selected from an acrylic polymer and a polyester polymer. The radiation curable resins are particularly useful for coatings over non-metallic substrates such as ABS plastics, etc.. having an adherent, thin film of metal deposited by vacuum metallizing, sputtering, electroless deposition, electroplating, and the like.
