<P>PROBLEM TO BE SOLVED: To provide a resin composition excellent in heat resistance and dynamic characteristics, and having a high transparency, also, a resin solution suitable for producing a phase differential film in an industrial scale and excellent in a long time preservation stability, and a high quality negative phase differential film. <P>SOLUTION: This resin composition consists of (a) 30-95 wt. % N-phenyl-substituted maleimide-olefin copolymer consisting 55-65 mol % specific N-phenyl-substituted maleimide residue unit and 45-35 mol % specific olefin residue unit, and (b) 70-5 wt. % styrene composition consisting of at least ≥1 kind residual unit selected from a group consisting of a styrene-based monomer residual unit, a vinyl cyanide-based compound residual unit, an acrylic acid alkyl ester residual unit and a methacrylic acid alkyl ester residual unit, and having 95-60 mol % styrene-based monomer residual unit. Further, the negative phase differential film consisting of the same is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
