With a total of seven patents to his name, Shimizu has made significant advancements in the production of innovative materials that change color in response to temperature variations.

Latest Patents

Shimizu's latest patents include a process for producing linear material and a thermochromic color masterbatch. The process for producing linear material involves dipping a core, either monofilament or multifilament, into a vinyl chloride resin sol composition that contains thermochromic particulate material. This material is prepared by enclosing an electron-donating chromogenic substance and an electron-accepting substance within a high polymer compound, along with a solvent. The core is then withdrawn from the sol composition and heated to gel the composition, resulting in a coated core. The thermochromic color masterbatch is designed for use in thermoplastic resin and consists of a wax with thermochromic granular material that is coated with a hydrophilic high-molecular weight substance.
