Abstract
A process including providing a coating head having an external opening in flow communication with a source of a first coating liquid, positioning the coating head relative to a substrate to define a gap between the external opening and the substrate, creating relative motion between the coating head and the substrate in a coating direction, and dispensing a predetermined quantity of the first coating liquid from the external opening onto at least a portion of at least one major surface of the substrate to form a discrete patch of the first coating liquid in a predetermined position on at least a portion of the major surface of the substrate. The first coating liquid as dispensed exhibits a viscosity of at least 1 Pascal-sec. In some exemplary embodiments, the first coating liquid is a liquid optically clear adhesive composition used in a laminate including a light emitting or reflecting device component.
