<P>PROBLEM TO BE SOLVED: To provide an optical film excellent in adhesion and hardness. <P>SOLUTION: In the optical film, an adhesion layer and a hard coat layer are provided to one surface of an optically-transparent substrate in this order from the side of the optically-transparent substrate. The adhesion layer is made of a composition mainly comprising a resin of the same kind as a resin constituting the optically-transparent substrate and glass transition temperature of the adhesion layer is lower than that of the optically-transparent substrate. The hard coat layer is formed of a cured product of a curable resin composition for the hard coat layer. Further there is a transition area which has both components of the adhesion layer and of the hard coat layer in a mixed state between the adhesion layer and the hard coat layer. <P>COPYRIGHT: (C)2011,JPO&INPIT |
