Abstract
A photothermographic composite structure for use in a solvent-free dye thermal positive imaging diffusion-transfer process comprising: PA1 (a) an image-receiving element comprising a polymeric dyeable image-receiving layer having a glass transition temperature in the range of 20.degree. to 200.degree. C., and PA1 (b) strippably adhered to said image-receiving element, an imageable photothermographic element comprising in at least one layer thereof a binder, a silver source material, photosensitive silver halide in catalytic proximity to said silver source material, and a formazan dye.
