Coating method for thermographic imaging element, coating solution for thermographic image forming layer, thermographic imaging element, and photothermographic imaging element

摘要

In a process for the preparation of a thermographic imaging element, a coating solution containing an organic silver salt and a binder is applied. The coating solution should have a viscosity at 25°C of 500-500,000 mPa·s at a shear rate of 0.1 s^-1 and 0.1-100 mPa·s at a shear rate of 1,000 s^-1. A coating free of streaks and wind-swept variations can be formed at a high speed. Thermographic and photothermographic imaging elements having improved surface quality and a satisfactory imaging capability are obtained.
