ABSTRACT:
Thermally developable imaging materials have an outermost protective layer that is composed of one or more hydrophilic film-forming components. Between the outermost protective layer and the underlying thermally developable imaging layers is an interlayer containing a film-forming ionic latex polymer other than a carboxy-containing latex polymer. This ionic polymer can be negatively-charged or positively-charged. The ionic latex polymer is present as latex particles that have been prepared in the presence of a stabilizer in an amount of at least 0.5% (by weight) that has an HLB value of 7 to 20. The stabilizer becomes associated with the latex polymer particles. Both thermographic and photothermographic materials can be prepared with such protective layers.
