Title: Eiki Kunimoto: Innovator in Transparent Film Technology
Introduction
Eiki Kunimoto is a notable inventor based in Fuji, Japan. He has made significant contributions to the field of materials science, particularly in the development of transparent films. With a total of 2 patents to his name, Kunimoto's work focuses on enhancing the properties of cyclic olefin resins.
Latest Patents
Kunimoto's latest patents include a groundbreaking transparent film that boasts heat resistance and improved brittleness. This innovative film is characterized by an internal haze value of 1.0% or less and incorporates a cyclic olefin resin with a refractive index of n1 and a glass transition temperature (Tg) of 170°C or more. Additionally, it features a styrene elastomer with a refractive index of n2, ensuring that the difference in refractive indices, denoted as Δn=|n2−n1|, is 0.012 or less. Furthermore, the heat-resistant transparent film may contain multiple types of styrene elastomers, and the cyclic olefin resin can be a copolymer of norbornene and ethylene.
Another significant patent involves an antihazing agent designed for noncrystalline cycloolefin resins. This agent effectively inhibits hazing caused by fine cracking due to environmental changes, particularly from high temperature and humidity to ordinary conditions. It maintains the inherent characteristics of the resins, preserving their transparency and preventing a decrease in light transmittance. The antihazing agent comprises a compound component with a metal rosinate as the main ingredient, and it is enhanced by the inclusion of alkali metal salts, alkaline earth metal salts, and Group 12 metal salts.
