Donor element for laser color transfer.

摘要

A donor element for laser color transfer processes includes a heat absorbing layer including a combination of a metal layer with an antireflecting layer having an index of refraction greater than 2. The heat absorbing layer may include a metal or an alloy either in single or multiple layers having a thickness sufficient to yield a heat capacity of less than 0.2 calories per degree Centigrade per square meter and an optical density at the laser wavelength of 1.0 or greater. <IMAGE>
