<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of optical films, in which two or more function layers can be simultaneously subjected wet-on-wet coating, a high productivity is attained and adhesion between layers is high, and there is no trouble for function separation between layers. <P>SOLUTION: This invention relates to the manufacturing method of optical films, in which a hard coat layer or an antidazzle layer (A) and a refractive index control layer (B) are laminated on a transparent substrate in this order, wherein the resin composition for forming layers (A) and (B), which contain an ionizing radiation curable resin respectively, is simultaneously subjected to wet-on-wet coating, and the first irradiation with ionizing radiation is applied and then drying is performed, and the second irradiation with ionizing radiation is applied for hardening. <P>COPYRIGHT: (C)2009,JPO&INPIT |
