摘要

In the preparation of the AgX/[AgO_2CR]_2 components that are used in photothermographic imaging films, where X = Br or Cl and R = linear alkyl chain, the reaction of silver ions with sodium fatty acid salts produces various silver soap structures containing different interface properties, depending on the starting silver ion source. Use of pre-prepared silver bromide microcrystals and silver nitrate, for example, has been shown to produce a AgBr/[AgO_2CR]_2 epitaxial interface. Conversely, we now find that silver chloride can be reacted directly with NaO_2CR to prepare a [Ag(O_2C_nH_(2n-1))]_2 product without needing to add silver nitrate. In this article we report the results of our continuing investigation, by TEM and X-ray diffraction, of the nature of the interface formed between prepared silver halides and [AgO_2CR]_2.
