OPTICAL FILM

摘要

An optical film comprising at least one layer made of a polyolefin resin composition which comprises 8-30 wt.% the following ingredient (A) and 92-70 wt.% the following ingredient (B) (provided that the sum of the ingredients (A) and (B) is 100 wt.%). Ingredient (A): An olefin polymer in which neither a crystal fusion peak corresponding to a quantity of heat of crystal fusion not smaller than 30 J/g nor a crystallization peak corresponding to a quantity of heat of crystallization not smaller than 30 J/g is observed in the range of from -50 to 200°C in an examination by differential scanning calorimetry in accordance with JIS K 7122. Ingredient (B): A propylene polymer in which a crystal fusion peak corresponding to a quantity of heat of crystal larger than 30 J/g or a crystallization peak corresponding to a quantity of heat of crystallization larger than 30 J/g is observed in the range of from -50 to 200°C in an examination by differential scanning calorimetry in accordance with JIS K 7122.
