FILM FOR OPTICAL USE, TRANSPARENT CONDUCTIVE MEMBER USING THE SAME, AND TRANSPARENT TOUCH PANEL |
摘要 |
<p>Disclosed is a film for optical use, wherein interference variations are not conspicuous, while maintaining adequate hard coat properties and perspective resolution. Specifically disclosed is a film for optical use comprising a foundation layer (22) arranged between a base layer (21) and a resin layer (23) having hard coat properties. Assuming the refractive index of the base layer (21) is na, the refractive index of the foundation layer (22) is nb and the refractive index of the resin layer (23) is nc, the following relation: na = nb = nc or na = nb = nc (provided that na ? nc) is satisfied. The difference between the refractive index na of the base layer (21) and the refractive index nc of the resin layer (23) is 0.5 or less. Consequently, the difference of refractive indexes between adjacent layers can be small, thereby suppressing interference variations and maintaining adequate perspective resolution.</p> |
