DYE DONOR ELEMENT FOR LASER-INDUCED HEAT-SENSITIVE DYE TRANSFER

摘要

PURPOSE: To provide a method for improving the tone scale in a laser induced heat-sensitive coloring matter transfer device. CONSTITUTION: A coloring matter donative body element for the laser induced heat-sensitive coloring matter transfer contains a substrate with a coloring matter layer containing an image coloring matter in a binder and an infrared ray absorbing matter combined with the image coloring matter. The binder contains an inorganic colloid, for example, a colloidal titanium dioxide or a colloidal silica oxide.
