Latest Patents

Naitou's latest patents focus on the development of an azo-metal chelate dye and an optical recording medium. The azo-metal chelate dye is a compound that utilizes a 1,3,4-thiadiazole ring as the diazo component. This diazo component is combined with a coupler component that includes condensed rings with a fluorine-substituted alkylsulfonylamino group and an amino group. The resulting azo dye compound forms chelate bonds with metals such as Co, Ni, Cu, and Pd. The optical density ratio (OD2/OD1) of the two absorption bands in the absorption spectrum is greater than 1.25, which is a key characteristic of this dye. This innovation enables the creation of an optical recording medium capable of high-speed recording.
