Abstract
Molded articles or substrates having an in-mold coating thereon are disclosed. The in-mold coated substrates are produced by a method wherein the flow of the in-mold composition onto the substrate can be selectively controlled. The molded articles can be preferentially coated in desired or predetermined areas with in-mold coating compositions by controlling the thickness or depth of various sections of the substrate. A molded article or substrate is provided with a removable in-mold coating containment flange which extends completely around the perimeter of a surface to be coated in order to substantially contain the in-mold coating within the mold cavity and on the desired area of a part before the coating has been cured.
