Latest Patents

One of Onishi's latest patents is focused on blowing agents of tetrazoles and their derivatives. This novel blowing agent is characterized by being harmless, odorless, and inexpensive. It is low in physical sensitivities and safe for use, generating clean gas through sharp decomposition at elevated temperatures. The blowing agent employs aminotetrazole derivatives, offering applications in foaming agents for resin molded bodies, inflators for airbags, and smoking agents for diffusing chemicals through a cost-effective synthetic process.

Another significant invention by Onishi is a nonvolatile thermal micro-capsule toner. This innovative toner addresses the common issue of pattern vanishing in conventional toners. It consists of micro-capsules made from two or more types of compositions, with a component that thermally decomposes to generate gas added to the micro-capsule's core or interface. This toner can be applied to paints, adhesives, or moldable resins, allowing for the development of nonvolatile patterns through simple heating. It enables printing on various materials, including paper, synthetic resins, wood, and metals.
