Optical plastic films, polarizing plates and image display devices

Abstract

This invention provides an optical plastic film that exhibits good scratch resistance relative to both hard and soft materials. The optical plastic film of this invention has a first surface and a second surface located on the opposite side of the first surface. The indentation hardness of the cross-section on the first surface side, the indentation hardness of the cross-section on the second surface side, and the indentation hardness of the cross-section at the midpoint of the thickness direction of the plastic film satisfy a predetermined relationship in the traveling direction and width direction. none
