Disclosed is a resin composition which is composed of a styrene copolymer and a norbornene polymer, while having excellent compatibility and being free from phase separation. This resin composition can be easily formed into a film. Also disclosed are an optical film mainly composed of this resin composition and having excellent transparency, such an optical film further having reverse wavelength dispersion, and uses of such an optical film. Specifically disclosed is a resin composition characterized by containing a styrene copolymer (A) having a structural unit (1) represented by the formula (1) below and a structural unit (2) represented by the formula (2) below, and a norbornene polymer (B). |
