热敏打印技术及热敏染料在彩色影像输出中的应用

The Application of Thermal Printing Technology and Thermal Dye in Color Image Output

全彩色热敏打印由于具有影像质量高、使用方便、利于环保等优点,成为彩色影像输出技术领域的发展方向。荧烷化合物具有在熔点下从无色到有色的互变结构,可通过变换取代基,得到黄、品、青系列染料,成为应用在热敏彩色影像输出技术中的主要染料类型。

Full-color thermal printing possessed advantages of high quality color images, convenient and environment friendly. It is the development trend of color image output technology. Fluorane compounds have tautomers of colorless form and colored form under the melting point. The yellow, magenta, cyan series dyes could be obtained by changing substituents of fluorane compounds. They had become the main type of dye applied in the field of thermal color images output.
