doi:10.7517/j.issn.1674-0475.2008.03.211

Abstract

Abstract: The effect of Pb²⁺ and Zn²⁺ on the photographic properties and storage stability of hydrophilic PTG materials using PVA as binder was respectively investigated. The results showed the thermal development fog and relative sensitivity of PTG materials were all significantly decreased by adding Pb²⁺ or Zn²⁺ to the coating dispersions, and those of PTG materials debased more quickly with the increase of percentage of Pb²⁺ or Zn²⁺. In addition, the thermal development fog increased slowly and relative sensitivity increased slightly relative to the primitive PTG materials after the PTG materials including Pb²⁺ or Zn²⁺ aged through different time.

Key words: Pb²⁺, Zn²⁺, photothermographic materials, photographic properties, aging stability
