<p>thermographic recording material, consisting of a substrate with layer(s) of a binder, a reducing agent and a Ag cp., contains Ag salt(s) (I) complexed with complexing agent(s) (II) with a total stability constant of 4.50-10.00, pref. is not 95% and esp. all of the total (I), except the Ag halide, being present in the form of a (I) complex. Pref. (I) is an (in)org. Ag salt and (II) contains an imidazole gp., which can complex Ag ions. The material contains 1-15 mole % Ag halide, w.r.t. the total Ag, in catalytic proximity to (I).</p> |
