Title:
CYCLIC OLEFIN RESIN COMPOSITION FILM
Document Type and Number:
WIPO Patent Application WO/2015/198686
Kind Code:
A1
Abstract:
Provided is a cyclic olefin resin composition film having excellent in-plane retardation. The cyclic olefin resin composition film includes a cyclic olefin resin (11), and a styrene elastomer (12) conforming to ISO 1133 and for which a value of a melt flow rate, measured under a condition of 230°C and 2.16 kgf, divided by the amount of ethylene units is 0.18 g/(10 min·mol%) or more. As a result, tear strength can be improved and increase in retardation (R0) in an in-plane direction can be suppressed.
