Title: Inventor Takahiro Sakakibara: Innovation in Anti-Reflection Films

Introduction

Takahiro Sakakibara is a distinguished inventor based in Tokyo, Japan, whose contributions to technology have resulted in four patents. He has played a significant role in advancing materials science, particularly in the development of innovative anti-reflection films.

Latest Patents

Sakakibara's latest patents focus on an anti-reflection film characterized by a laminated structure. This film includes a substrate, a hard coat layer, and an anti-reflection layer, featuring a luminous reflectance of 2% or less on the anti-reflection layer's surface. Notably, one of the key innovations is its exceptional bending resistance, achieved through a unique cylindrical mandrel method. The minimum value of the mandrel diameter indicating bending resistance is in the range of 6 mm or less when bent inward, and 10 mm or less when bent outward. This anti-reflection film not only provides high bending resistance but also ensures excellent anti-reflective properties.

Furthermore, the film includes an anti-reflection layer with a surface having a coefficient of kinetic friction and a coefficient of static friction both at 0.3 or less. After a rigorous rubbing test using fine steel wool, the haze value remains consistent with a difference of 0.1% or less, illustrating its high scratch resistance alongside its anti-reflective attributes.
