With its excellent color and tone reproduction, thermal dye transfer printing produces continuous-tone color images that rival silver halide photography. However, conventional thermal dye transfer images fade easily when subjected to light or to heat. Many approaches have been taken to solve this serious problem, including the addition of a protective layer over the dye receiver sheet, the addition of UV-light-absorbing agents and antioxidizing agents to the dye receiving layer, the addition of dye adsorbents to the dye receiving layer, the hardening of the dye receiving layer after thermal printing, and the employment of chemical reactions between reactive dyes and chemical agents in the dye receiving layer. Each of these approaches has had some success, but the last approach has been most promising.
In this paper, we describe the various methods to improve image stability and our study of the chelate system providing exceptionally high image stability.
