| 摘要 |
The present invention relates to a rainbow reduction optical polyester film and, more specifically, to a rainbow reduction optical polyester film having an excellent adhesive force with a primer layer, a polyester film base material, and an optical functional layer, having excellent optical properties, and capable of reducing a rainbow phenomenon by adjusting a refractive index. According to the present invention, the rainbow reduction optical polyester film is formed by applying a coating solution containing polyurethane resin, isocyanate hardener, an oxazoline curing agent, and inorganic nanoparticles to at least one side of an optical polyester base film, and is characterized by including a primer layer whose refractive index is 1.55-1.65. |
