Abstract: A non-photosensitive core-shell silver salt can be used in thermographic and photothermographic imaging compositions and materials. This core-shell silver salt includes one or more silver salts in the core, at least one of which is different from the one or more silver salts used in the shell. The molar ratio of the different silver salts in the core and shell is from about 0.01:1 to about 100:1.
