Title: **Chiaki Sekioka: Pioneer in Latent Image Technologies**
Introduction
Chiaki Sekioka, an innovative inventor based in Inagi, Japan, has made significant contributions to the field of image technologies. With a total of nine patents to her name, Sekioka is recognized for her groundbreaking work in latent image printing and deciphering methods.
Latest Patents
Among her latest patents, Sekioka has developed a **latent image printing ink composition**, which incorporates an organic fluorescent substance. This substance responds to an excitation wavelength range of 600-850 nm and emits fluorescence within a wavelength range of 651-900 nm. Her inventions also include prints containing latent images created with this ink composition and a sophisticated apparatus for deciphering latent image data. The deciphering device features an emitting element that irradiates prints with the excitation wavelength, a receiving element that detects the resulting fluorescence, and a computer processor that interprets the emission against a standard value. This innovative approach allows reliable discrimination of article genuineness without third-party knowledge.
Furthermore, Sekioka has patented an **erasing method** that improves the recording and erasing process on various media. In one aspect, a non-catalyst-containing recording agent is used along with a liquid-state catalyst for effective erasing through heating and near-infrared irradiation. Additionally, she has devised a method where a catalyst-containing recording agent undergoes simultaneous heating and irradiation during erasing.
