Document Type and Number:
WIPO Patent Application WO/2015/080167
Kind Code:
A1
Abstract:
A cycloolefin-based resin composition film which exhibits excellent preservation stability against environmental changes and excellent toughness is provided. This composition film comprises both a cycloolefin-based resin (11) and a styrene-based elastomer (12) which exhibits a melt flow rate of 4.5g/10min or less as determined according to ISO 1133 at 230ºC under a load of 2.16kgf. The styrene-based elastomer (12) is dispersed in the cycloolefin-based resin (11) with the content of the elastomer (12) being 5 to 35wt%, and the minor axis diameters of the dispersed particles of the styrene-based elastomer (12) are 2μm or less. Thus, excellent preservation stability against environmental changes and excellent toughness can be attained.
