Abstract
Photothermographic materials provide images having improved image stability due to the presence of certain image stabilizing compounds in a silver-containing layer. These image stabilizing compounds are fluorenone, fluorene, coumarin, naphthalic acid imide, pyrazoline, or anthracene compounds. In particular, they reduce image browning that may occur from the presence of various components in the materials.
