Title:
ANTISTATIC ANTIREFLECTIVE FILM CAPABLE OF PREVENTING OCCURRENCE OF INTERFERENCE FRINGE
Document Type and Number:
WIPO Patent Application WO/2005/098481
Kind Code:
A1
Abstract:
An antireflective film that is capable of preventing the occurrence of interference fringe, having antistatic properties and excels in coating film adherence. There is provided the first form of antireflective film comprising transparent base film (1) and, superimposed in sequence thereon, antistatic hard coat layer (2-1) containing an antistatic agent selected from among polymer antistatic agents, low molecular antistatic agents having crosslink groups, and conductive antistatic agents and exhibiting hardness and low refractive index layer (3) having a refractive index lower than that of an underlayer in direct contact therewith. The occurrence of interference fringe is prevented by adjusting the absolute value of refractive index difference between the transparent base film (1) and the antistatic hard coat layer (2-1) to ≤0.03.
