Abstract

A method of coating well defined discrete areas of a flexible substrate by creating a lyophobic pattern on the surface of the web to leave a desired pattern of lyophilic areas. A layer of coating solution is laid down over the patterned web, the solution withdrawing from the lyophobic areas and collecting on the lyophilic areas.

Description

field of invention [0001] The present invention relates to the field of coating, and in particular to the roll-to-roll coating of well-defined discrete areas of a continuous web (web) of material. Background technique [0002] It is known to use the fundamental principle of differential wetting to condition liquids on solid supports such as silicon wafers. The general principle consists in the spontaneous movement of liquid from the lyophobic (solventphobic) regions of the substrate or carrier to the lyophilic (solventophilic) regions. [0003] WO 02 / 38386 discloses a method and apparatus for patterning using a temperature gradient. The temperature gradient is used to condition the liquid after coating. [0004] EP 0882593 discloses a method of forming a hydrophobic / hydrophilic front side of an inkjet printer. Hydrophobic surfaces around the printhead nozzles are needed to repel ink from the nozzles, and hydrophilic areas are needed to pull ink away from the hydrophobic a...
