摘要：
Ionic liquids are added to black-and-white direct thermographic materials to provide increased image density or to allow for reduced silver coverage (that is, improved silver efficiency). Useful ionic liquids include imidazolium, pyrazolium, pyridinium, pyrimidinium, pyrazinium, tetra-alkylammonium, or tetra-alkylphosphonium cations.
