Abstract:
1. A hydrophilic member comprising: a substrate; a hydrophilic film formed by heating and drying a hydrophilic composition; and an undercoat layer comprising a nonvolatile catalyst between the substrate and the hydrophilic film, wherein the hydrophilic composition comprises: (A) a hydrophilic polymer represented by the following general formula (I); (B) an alkoxide compound of an element selected from Si, Ti, Zr and Al; and (C) a catalyst that promotes the reaction of (A) the hydrophilic polymer and (B) the alkoxide compound: wherein R L m represents an integer of from 1 to 3, x and y represent a polymerization ratio by mol of the repeating units of the formula (I) and the polymerization molar ratio x/y is within a range of from 99/1 to 10/90, and wherein (a) L (b) L wherein R R R wherein said hydrophilic film has a surface free energy of 79-85 mN/m.
