Multi-color transfer printing medium. |
摘要 |
<p>A multi-color transfer printing medium is comprised of at least two different kinds of microcapsules having a porous membrane and disposed on a substrate. Each kind of microcapsules contains a different electron-donating chromogenic material effective to produce a different color tone, and a different light-absorbing material effective to absorb a light of different wavelength. In use, the multi-color transfer printing medium is superposed with a color developing sheet coated with electron-accepting material, and is irradiated with lights of different wavelengths to transfer-print color image on the developing sheet to thereby obtain the multi-color image with a simple process at high speed.</p> |
