Latest Patents

One of Kira's latest patents is titled "Process for producing encapsulated metal colloids as inorganic coloured pigments." This invention involves a method for producing encapsulated metal colloids that serve as inorganic colored pigments. The process includes reacting glass-forming components through the sol-gel method to create a sol that disperses a metal salt. An additional reducing agent is used to form metal colloids, which are then converted into xerogel-encapsulated metal colloids through spray drying and subsequent heating. The resulting inorganic colored pigments are characterized by a high proportion of metal colloid, at least 80%, within the capsules.

Another significant patent is the "Photochromic coating composition comprising nanoscale particles and process for providing substrate coated with the same." This coating composition features a silicon-containing precondensate derived from a hydrolysable silane, a photochromic dye, a stabilizer, and nanoscale particles. When applied to transparent plastic and glass substrates, the coating exhibits high light stability and excellent scratch resistance after curing.
