The Influence of Metallic Stearates on the Photographic Properties of Photothermographic Material Based on Silver Tolyltriazole

doi:10.7517/j.issn.1674-0475.2008.02.94

Abstract

Abstract: The influence of metallic stearates on the photographic properties of photothermographic (PTG) material based on silver tolyltriazole(AgTTA) was reported. The results showed that the stearates can accelerate the development of PTG material. The addition of NiSt₂ greatly increased the maximum density and the sensitivity together with a slight fog increase. However the addition of BaSt₂ and CaSt₂ did not make such great increase in the maximum density and the sensitivity, together with a slight fog decrease. The development processes were discussed by studying the effect of component and content on pH, [Ag⁺] and the photographic properties.

Key words: stearates, silver tolyltriazole, development accelerator, photothermographic material
