OPTICAL ADJUSTMENT LAYER-EQUIPPED HARD COAT FILM FOR TRANSPARENT CONDUCTIVE FILM, AND TRANSPARENT CONDUCTIVE FILM

WIPO Patent Application WO/2019/012733

A1

Provided is an optical adjustment layer-equipped hard coat film for transparent conductive film, the optical adjustment layer-equipped hard coat film being able to acquire sufficient blocking resistance and inhibit visibility reduction even in a transparent conductive film to which a transparent conductive layer is provided. The optical adjustment layer-equipped hard coat film is provided with: a transparent base material film comprising a non-crystalline polymer; and a hard coat layer and an optical adjustment layer thereabove that are stacked in this order on one surface of the transparent base material film. The optical adjustment layer contains a plurality of particles, and the average particle diameter of the particles is greater than the average film thickness of the optical adjustment layer, with an average particle diameter r1 and an average film thickness d1 satisfying the relationship of 50 nm ≤ (r1 - d1) ≤ 1900 nm. The arithmetic average roughness Ra in a specific portion other than at protrusions formed by the particles in the surface of the optical adjustment layer is in the range of 0.3-20 nm.
