Hydrophilic coating, hydrophilic film-forming article, coating solution for forming hydrophilic film, and method for producing hydrophilic film-forming article

摘要

PROBLEM TO BE SOLVED: To provide a hydrophilic coated film and a hydrophilic coated film forming article achieving both of water scale removability and film hardness, of which both achievement at same time is difficult with a conventional products although a hydrophilic coated film achieving both of water scale removability and film hardness is strongly required.SOLUTION: There is provided a hydrophilic film containing a copolymer by polymerizing a (meth)acrylate monomer (a) having a sulfonic acid group, a group of sulfonate or a thiol group, represented by the formula (1) as an A component, a polymerizable monomer (b) having 3 or more (meth)acryloyl groups in a molecule as a B component and a (meth)acrylate monomer c) having an alkoxysilane group and an acetoxy silane group as a C component at specific (0.8≤a≤11, 1.0≤b≤95, 1.0≤c≤96 with a+b+c=100 mol%) ratio.SELECTED DRAWING: Figure 1
