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 the amount of H2PA increased. We also found that the development of silver benzotriazole materials was promoted by the introduction of PHZ, and the promotion was strengthened by increasing the amounts of PHZ. The analysis data of SEM and IR indicated that a silver complex, which was supposed to be easy to transmit silver ions to development center to promote development, have been produced by introducing PHZ into the silver benzotriazole materials. The sharp of silver benzotriazole grains were changed by the silver complexes. The XRD data showed that the silver complexes had the same crystal structures as silver benzotriazole.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
