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.
