Abstract
An in-mold coating composition particularly useful for in-mold coating of molded nylon based substrates comprises a coreactive addition polymerizable composition of urethane-acrylate oligomer having at least two acrylate and/or methacrylate terminal groups, at least 0.2% of a sulfonic acid functional acrylate or methacrylate, at least 0.2% of acrylic and/or methacrylic acid, with the balance being coreactive polymerizable diacrylate(s) and/or ethylenically unsaturated monomer(s).
