<P>PROBLEM TO BE SOLVED: To provide an optical transparent resin film having excellent transparency, haze properties and surface smoothness even in a step of a raw film which is not drawn and having moderate sliding properties without generating optical unevenness accompanying appearance defects such as a blocking mark upon long time preservation and a wrinkle and a crack generated upon secondary working even when a protective film is not stuck. <P>SOLUTION: In the optical transparent resin film having a two layer construction film including a layer A and a layer B, the layer B contains a cyclic olefin polymer and the layer A contains a thermoplastic resin and 0.1 to 1.0 pts.mass aliphatic amide based lubricant to 100 pts.mass thermoplastic resin. In the optical transparent resin film having a three layer construction film formed by layering a layer A, a layer B and a layer C in this order, the layer B contains a cyclic olefin polymer, the layer A and the layer C contain a thermoplastic resin and the layer A and/or the layer C contains 0.1 to 1.0 pts.mass aliphatic amide based lubricant to 100 pts.mass thermoplastic resin. <P>COPYRIGHT: (C)2010,JPO&INPIT |
