Laminated Thermoplastic Resin Film and Laminated Thermoplastic Resin Film Roll |
摘要 |
[PROBLEMS] The present invention provides a laminated thermoplastic resin film which is excellent in adhesion and blocking resistance. [MEANS FOR SOLVING PROBLEMS] A laminated thermoplastic resin film has a covering layer containing a copolymerized polyester resin and a polyurethane resin on one side or both sides of a thermoplastic resin film, characterized in that the covering layer has a microphase-separated or nanophase-separated structure in PEs phase A comprising a copolymerized PE resin as a main component and PU phase B comprising a PU resin as a main component, and when the covering layer is observed by a scanning probe microscopy in phase measurement mode, an area ratio (surface fraction of PEs) of PEs phase A (which indicates a dark phase in phase image) of the surface of the covering layer defined by following formula ( 1 ) is 35% or more and less than 90% per a measurement area of 5 mumx5 mum. <?in-line-formulae description="In-line Formulae" end="lead"?>Surface fraction of PEs(%)=(area of PEs phase A/measurement area)x100 (1)<?in-line-formulae description="In-line Formulae" end="tail"?>
