Abstract
A dispersion-preventing patterned substrate suitable for a liquid crystal display device is described. The substrate is patterned with a resin which is a cure of a coating composition comprising a solution of: a) a crosslinkable polymeric surfactant having i) at least one pendant fluorocarbon moiety, and ii) a plurality of pendant ionic moieties which are capable of reacting with counterions to form a crosslinked polymer; and b) a polymeric crosslinking agent having a plurality of ionic or potentially ionic moiety counterions capable of reacting with the ionic moieties of the surfactant, wherein the pattern defines a plurality of wells adapted to receive a coloring agent.
