Abstract
A process including positioning a coating head to define a gap between a first external opening in flow communication with a source of a first coating liquid, and a major surface of a substrate; creating relative motion between the first coating head and the substrate; dispensing a pre-determined quantity of the first coating liquid to form a discrete patch in a predetermined position on the substrate's major surface; positioning a second coating head to define a gap between a second external opening in flow communication with a source of a second coating liquid and a major surface of the patch; creating relative motion between the second coating head and the substrate, and dispensing a pre-determined quantity of the second coating liquid to form a discontinuous pattern on the patch's major surface. The first and optionally the second coating liquids exhibit a viscosity as dispensed of at least 1 Pascal-sec.
