AI Technical Summary
Technical Problem
Conventional anti-reflection films lack sufficient thermoformability and abrasion resistance, which are essential for applications in display technologies and optical components.
Method used
An anti-reflection film comprising a base material layer made of thermoplastic resin and a high-refractive-index layer with a polymer of urethane (meth)acrylate derived from fluorene-based diol, isocyanate, and (meth)acrylate, where the high-refractive-index layer includes zirconia, providing enhanced thermoformability and abrasion resistance.
Benefits of technology
The film achieves low surface reflectivity, excellent thermoformability, and high abrasion resistance, making it suitable for applications in computer displays, plasma displays, and optical components.

Abstract
The present invention enables the achievement of: an antireflection film which is a multilayer body that has low surface reflectance, while having excellent heat moldability and good scratch resistance; and the like. The above are achieved by means of an antireflection film which comprises a base material layer that contains a thermoplastic resin and a high refractive index layer that is superposed on at least one surface of the base material layer, while having a refractive index that is higher than the refractive index of the base material layer, and which is configured such that the high refractive index layer contains a fluorene diol, an isocyanate and a polymer of a resin material that contains a (meth)acrylate and a urethane (meth)acrylate derived from a (meth)acrylate.
