<P>PROBLEM TO BE SOLVED: To provide a refractive index control thin film of which the refractive index can be made low even on an optical film, giving a low refractive index film which suppresses haze and excels in antifouling property. <P>SOLUTION: The refractive index control thin film comprises at least a thermally decomposable polymer having a ceiling temperature lower than 20°C and a matrix polymer having a softening temperature higher than 60°C. <P>COPYRIGHT: (C)2008,JPO&INPIT |
