Title: Kohei Kiyota: Innovator in Thermal Printing Technology
Introduction
Kohei Kiyota is a prominent inventor based in Machida, Japan. He has made significant contributions to the field of thermal printing technology, holding a total of 4 patents. His innovative work focuses on improving the quality and efficiency of thermal ink sheets used in printing applications.
Latest Patents
One of Kiyota's latest patents is for an ink sheet usable in thermal recording. This reusable thermal ink sheet features a thermal ink composition layer formed on a substrate. The thermal ink composition is a mixture of ink material and filler. The ink material includes a coloring agent and a low-temperature melting compound, which is solid at room temperature but melts during thermal printing in response to the printing image to be transferred. The low-temperature melting compound contains a urethane compound as a base material, along with additive materials that act as viscosity modulators, lowering the viscosity of the ink material at printing temperature. These additive materials include fatty acid compounds, fatty acid amide compounds, and ester compounds. The improved ink sheet ensures that a high-quality printing image is transferred to plain paper with a rough surface, even after multiple thermal printing occurrences. Additionally, it prevents ghost images and eliminates background noise. A plasticizer is also added to enhance the thermal printing ability at lower temperatures.
