Abstract (en)
Toning agents are provided for use in thermographic and photothermographic materials, either on their own or in combination with at least one other toning agent, with improved compatibility with hydrophobic media as shown by reduced crystallization and reduced diffusion through the material, which properties enabling an improved imaging performance to be achieved and in particular a more neutral image tone after storage.
