Development accelerator for thermographic materials

Thermal recording material containing a suitable substrate coated with an image forming layer. The image forming layer contains a thermally reducible source of silver, a 3-indazolinone or urea compound; a polymeric binder; and optionally, an auxiliary reducing agent and toner. Preferably, an anti-st...

More Information
Summary:Thermal recording material containing a suitable substrate coated with an image forming layer. The image forming layer contains a thermally reducible source of silver, a 3-indazolinone or urea compound; a polymeric binder; and optionally, an auxiliary reducing agent and toner. Preferably, an anti-stick layer is coated on top of the imaging layer. The 3-indazolinone and urea compounds have been found to enhance the thermal image forming capability of thermal recording material.
