Provided are an active energy
ray-curable composition, a cured
coating film, and a thin film which are coated on the surface of a substrate and cured to impart antistatic properties, and which have transparency and light
transmittance to a degree that can be used in optical applications, and which have scratch resistance and bending resistance. The composition contains components (A) to (D), the content of component (C) is 4 parts by
mass or less relative to 100 parts by
mass of the resin
solid content in the composition, and 10% by
mass or more of a resin component having a
hydroxyl value of 60 mgKOH / g or more is not contained relative to 100% by mass of the resin
solid content in the composition. Component (A): a
photoinitiator containing a water-soluble
photoinitiator (a1); component (B): a polyfunctional (
meth)
acrylate containing an oxyalkylene chain-containing compound (b1). Component (C):
conductive polymer microparticles; component (D): an
organic solvent containing a
solvent (d1) having a
boiling point of 130 DEG C or higher and a
Hansen solubility parameter [
delta] H12.0 or higher.
