<p>An electromagnetic wave shield layer with vacuum deposited metal using water dispersed polyurethane is provided to prevent the crack of plastic products and to be environment-friendly by using non-solvent type metal deposition layer. An electromagnetic wave shield layer with vacuum deposited metal using water dispersed polyurethane includes a plastic layer, a water dispersed polyurethane primer layer, and a metal deposited layer. The water dispersed polyurethane primer layer is formed on the plastic layer. The metal deposited layer is formed on the water dispersed polyurethane primer layer. The water dispersed polyurethane primer layer is formed by the spray-drying of a spray composition including the water dispersed polyurethane.</p> |
