Title: Satoshi Yanagida: Innovator in Photocurable Resin Technology
Introduction
Satoshi Yanagida is a notable inventor based in Tochigi, Japan. He has made significant contributions to the field of photocurable resin compositions, particularly for protective films used in optical devices. With a total of 3 patents to his name, Yanagida's work has had a substantial impact on the industry.
Latest Patents
One of his latest patents is a solvent-free photocurable resin composition designed for protective films. This innovative composition can be applied to the surface of optical discs, forming a highly transparent protective layer that adheres stably and effectively protects against scratches. The formulation includes a urethane(meth)acrylate oligomer, a trifunctional (meth)acrylic acid ester monomer, a photopolymerization initiator, and a dilution monomer. The dilution monomer is particularly noteworthy as it contains a fluorine-based (meth)acrylic acid ester monomer with three or more fluorine atoms, along with a monofunctional or difunctional (meth)acrylic acid ester monomer in specific weight percentages.
Another significant patent involves compositions for protective films for optical discs. These compositions consist of inorganic microparticles dispersed in an acrylic radical-based binder resin. The binder resins are created from various monomers, including base components, scratch-resistant components, and diluent components. The diluent components feature monomers with principal chain structures that include functional groups with cyclic structures or branched carbon chain structures.
