A coating composition containing a solvent and a coating agent having an ionizing radiation-curable compound as a principal component thereof, wherein under the following condition for the concentration a (wt %) of the coating agent in the coating composition0<a≦60,the concentration a of the coating agent and the surface tension b (dyne/cm) of the coating composition satisfy the following relationship≦(−/15)+26,is applied onto a surface of a protective filmand curing is carried out to form a hard coating layer. Even in the case that projections or foreign bodies are present on the surface of the protective film, the hard coating layercan conceal these and hence can have high surface smoothness.
