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.
