Effects of Toners on Photothermographic Materials Based on Silver Benzotriazole

Abstract

The photothermographic(PTG) imaging materials are used as digital hardcopy imaging medium in diagnostic medical field. We obtained the hardcopy image by driving laser or thermal print head on PTG materials based on electronic data. Toners, as the most important of components to provide best image quality, is a compound added to modify the normally yellow-brown color of thermally generated Ag0 particles to black. In the paper, the effects of phthalic acid(H2PA) and phthalazine(PHZ) as toners on photothermographic materials based on silver benzotriazole had been studied. The results indicated that H2PA as a toner can promote development in higher pH of system and the promotion increased with t..
