<p>The present invention is directed to a radiation-curable liquid composition that includes an associative ethylenically unsaturated reactive blend, a resinous poly-(meth)acrylate oligomer and optionally an inert thermoplastic material. The associative reactive blend has a ratio of electron donating groups to electron withdrawing groups in the range of about 5:1 to about 1:5. An investment casting method that utilizes patterns produced from the cured composition is also described.</p> |
