A hard coat film having an adherence modifying substratum film consisting of adherence modifying layer (B) containing copolymerized PEs and PU superimposed on one major surface or both major surfaces of thermoplastic resin film (A) and having, superimposed on the surface of the adherence modifying layer (B) on either one major surface of the substratum film, hard coat layer (C) containing inorganic microparticles, characterized in that the adherence modifying layer (B) has a micro phase separation structure or nano phase separation structure of PEs phase and PU phase, and that when a cut plane of the hard coat film is observed in a phase measurement mode by the use of a scanning probe microscope, the ratio of area of PU phase of adherence modifying layer (B) in the zone from interface of the adherence modifying layer (B) with the hard coat layer (C) to a depth of 20 nm is in the range of 30 to 60%. ® KIPO & WIPO 2009
