CURABLE RESIN COMPOSITION FOR ANTISTATIC LAYER, OPTICAL FILM, POLARIZING PLATE, AND DISPLAY PANEL

摘要

Disclosed is a curable resin composition for antistatic layers that can form antistatic layers with sufficient antistatic properties and excellent adhesion with adjacent HC layers. Also disclosed is an optical film with said antistatic layer. Specifically disclosed is a curable resin composition for antistatic layers that is characterized by containing: (A) an antistatic agent; (B) a polyfunctional monomer with two or more photocuring groups per molecule and a molecular weight of 900 max.; and (C) a urethane acrylate with six or more (meth) acryloyl groups per molecule and a weight average molecular weight of 1,000 - 11,000; and wherein the ratio of (A) to the total amount of (A), (B), and (C) is 1 - 30 mass% and the ratio of (C) to the total amount of (B) and (C) is 1 - 40 mass%. Also specifically disclosed is an optical film provided with an antistatic layer with a film thickness of 1 - 5 µm formed by a cured product from the curable resin composition for antistatic layers, and a hard coat layer, which are provided on one surface side of a TAC substrate, from the TAC substrate side.
