COMPOSITION FOR FORMATION OF HIGH REFRACTIVE INDEX LAYER FOR ANTIREFLECTION FILM AND ANTIREFLECTION FILM COMPRISING HIGH REFRACTIVE INDEX LAYER COMPOSED OF THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a composition for formation of high refractive index layer for an antireflection film, capable of suppressing occurrence of a defect associated with aggregation of metal oxide fine particles and increase in luminous reflectance.;SOLUTION: A composition for formation of a high refractive index layer contains (A) polyfunctional (meth)acrylate and (B) metal oxide fine particles. When the volume of the polyfunctional (meth)acrylate (A) contained in the composition for formation of a high refractive index layer is defined as (V_A) and the volume of the metal oxide fine particle (B) is defined as (V_B), the volume ratio of the metal oxide fine particle (B) {V_B/(V_A+V_B)} is 15 to 37% relative to the total volume of the polyfunctional (meth)acrylate (A) and the metal oxide fine particle (B).;COPYRIGHT: (C)2013,JPO&INPIT
