Abstract: The object of the invention is to provide an improved coating. The coating comprises a high transmittance antireflection layer of a grass-like alumina made by atomic layer deposition technique and subsequent water immersion. The coating also comprises at least one coating layer on the layer of a grass-like alumina, an uppermost coating layer being a low-surface energy coating. The coating is also hydrophobic and transparent.
