Hard coat film, production method of the same, polarizing plate and display |
摘要 |
To provide hard coat films having high hardness, and uniform durability against scratching and high flatness even with a small thickness and a large width, and to provide a method producing the same. The hard coat films are provided with an actinic ray curable resin on a cellulose ester film thereof, the cellulose ester film containing a UV absorber and 2 or more plasticizers. One of the plasticizers is a polyalcohol ester type and the other one is a non-phosphate ester type. The cellulose ester film is produced by biaxially stretching of a cellulose ester film with a total acyl substitution degree ranging from 2.6 to 2.9, a number average molecular weight ranging from 80,000 to 200,000, and a ratio of a weight-average molecular weight to a number average molecular weight ranging from 1.4 to 3.0.
