Abstract
A process includes placing a mask over a substrate; delivering liquid film-forming compositions through the mask to the substrate; removing the mask to leave a multilayered raw shape on the substrate; and curing the multilayered raw shape to form the multilayered shaped film product disposed on the substrate. The mask has a delivery surface, an opposite surface and at least one aperture having a design corresponding to the desired shaped film product. The film-forming compositions are delivered through a multistream nozzle. The movement of the mask and the delivery of the first and second liquid film-forming compositions to the mask aperture are controlled to provide a volumetric flow rate of the first and second liquid film-forming compositions to the mask aperture corresponding to the volume of a void. The nozzle is in contact with the delivery surface of the mask.
