液体涂布的基板上的离散液体涂层以及在形成层合物方面的用途
摘要：
本发明公开了一种方法，所述方法包括定位涂布头以限定与第一涂布液体的供应源流体连通的第一外部开口与基板的主表面之间的间隙；产生所述第一涂布头与所述基板之间的相对运动；分配预定量的所述第一涂布液体，以在所述基板的主表面上的预定位置形成离散贴片；定位第二涂布头，以限定与第二涂布液体的供应源流体连通的第二外部开口与所述贴片的主表面之间的间隙；产生所述第二涂布头与所述基板之间的相对运动，并分配预定量的所述第二涂布液体，以在所述贴片的主表面上形成不连续图案。所述第一涂布液体和任选地所述第二涂布液体在分配时表现出至少1帕斯卡‑秒的粘度。
摘要（英）：

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.
