PROBLEM TO BE SOLVED: To provide a coating composition that imparts at least one of antireflection, easy cleaning and improved durability to a substrate coated therewith.SOLUTION: There is provided a coating composition comprising: nonspherical nanoparticles; spherical nanoparticles; optionally hydrophilic groups and optionally a surfactant; and a liquid medium comprising water and an organic solvent of 30 wt.% or less, if present, based on the total weight of the liquid medium. At least a portion of the nonspherical nanoparticles or at least a portion of the spherical nanoparticles comprises functional groups attached to their surfaces through chemical bonds. The functional groups comprise at least one group selected from the group consisting of an epoxy group, an amine group, a hydroxyl group, an olefin, an alkyne, a (meth)acrylato, a mercapto group, or combinations thereof.SELECTED DRAWING: None |
