低屈折率組成物、低屈折率膜、光学多層膜および反射防止膜

Document Type and Number:

Japanese Patent JP4759780

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a composition having a low refractive index and excellent in physical strengths and productivity at a low cost. SOLUTION: In the composition comprising as a main component a multi- functional acrylic compound represented by silica sol particles and dipentaerythritol hexacrylate (DPHA), the composition comprises at least 20% of silica sol particles having specific particle diameters (50-100 nm) to form a nano porous structure in the composition film to cause to reduce the apparent refractive index due to the nanoporous structure.
