<P>PROBLEM TO BE SOLVED: To provide a process for easily forming a hydrophilic coating by photolithography without using a dedicated device for hydrophilic treatment, and to provide a hydrophilic coating formed by the process. <P>SOLUTION: The process for forming a hydrophilic coating includes the steps of: (1) forming, on a substrate, a first coating resin layer including a first cationic polymerization resin and a first photoacid generator; (2) laminating, on the first coating resin layer, a second coating resin layer including a second cationic polymerization resin which includes an acid-cleavable linkage in its main chain, and a second photoacid generator which generates methide acid by irradiation with an active energy ray including ultraviolet light; (3) forming a coating by curing the first coating resin layer and the second coating resin layer through exposure of the first coating resin layer and the second coating resin layer to the active energy ray to conduct development; and (4) forming a hydrophilic coating by hydrophilizing a surface of the coating through heat treatment of the coating. A hydrophilic coating is formed by the process. <P>COPYRIGHT: (C)2012,JPO&INPIT |
