A UV sensitive dry silver photothermographic construction for graphic arts use can be freely handled for one to two minutes under cool white fluorescent lighting or incandescent lighting. The construction comprises in sequence: a. a substrate, b. a continuous layer of a dry silver dispersion coating containing an organic silver full soap/half soap blend, a reducing agent, halide ion, and a binder resin, and c. a continuous protective topcoat layer comprising a cellulose acetate resin admixed with an effective amount of a development accelerator, said construction further comprising (1) halide ion in said silver dispersion coating or in said topcoat layer, said halide ion being at least 96 mole percent chloride ion, said halide ion when present in said dispersion coating being admixed in said dispersion subsequent to the admixing of at least a portion of said binder resin with said organic silver soap blend, and (2) an antihalation agent in any of the aforementioned layers or in a separate layer. |
