Title: Hiroo Matsuda: Innovator in Reversible Recording Materials
Introduction
Hiroo Matsuda is a notable inventor based in Tsukuba-shi, Ibaraki, Japan. He has made significant contributions to the field of reversible recording materials, holding a total of 3 patents. His work focuses on innovative technologies that utilize cholesteric liquid crystals for advanced recording applications.
Latest Patents
Matsuda's latest patents include a reversible recording material based on thermal energy. This invention discloses a reversible recording material that contains a liquid crystal mixture comprising at least two cholesteric liquid crystal compounds. These compounds have a molecular weight of less than 2000 and a glass transition temperature of 30°C or higher. The compatibility of the two cholesteric liquid crystal compounds allows for effective recording. The process involves heating the material to a temperature where it transitions to a cholesteric liquid crystal phase, followed by rapid cooling to fix the reflecting color for recording purposes.
Another significant patent is the reversible recording medium and method. This invention features a support with a reversible light-absorbing layer and a cholesteric reflection layer. The cholesteric liquid crystalline compound in this layer can reversibly show iridescent colors through selective reflection. The patent also describes a method for recording images in this medium and a reversible recording apparatus that utilizes it.
