The present invention is directed to the use of a mixture of non-light sensitive organic silver salts in a color photothermographic system comprising a blocked developing agent for color imaging. At least one of the organic silver salts is the sole of primary silver donor during thermal development and at least one other organic silver salt, present at levels in the range of 30,000 to 60,000 mg/mol of silver halide, effectively inhibits fog during thermal development of the photothermographic element. In one embodiment, and the system comprises a mixture of at least two organic silver salts, wherein the first organic silver salt exhibits a cLogP of 0.1 to 10 and a Ksp of 7 to 14 and wherein the second organic silver salt exhibits a cLogP of 0.1 to 10 and a Ksp of 14 to 21.
L'invention concerne l'utilisation d'un mélange de sels d'argent organiques non photosensibles dans un système photothermographique couleurs comprenant un agent de développement bloqué destiné à l'imagerie couleurs. Au moins un des sels d'argent organiques est le donneur d'argent unique ou primaire pendant le développement thermique et au moins un autre sel d'argent organique, présent à des teneurs comprises entre 30,000 et 60,000 mg/mol d'halogénure d'argent, inhibe de manière efficace un voile pendant le développement thermique de l'élément photothermographique. Dans un mode de réalisation, le système renferme un mélange d'au moins deux sels d'argent organiques, le premier sel d'argent organique présentant un a cLogP compris entre 0.1 et 10 et un Ksp compris entre 7 et 14 et le second sel d'argent organique présentant un cLogP compris entre 0.1 et 10 et un Ksp compris entre 14 et 21.
