ABSTRACT:
A photographic, silver halide element that can be dried under rapid conditions during coating without deleterious effects on fog, kinks and other surface conditions, is described. This process can function with the addition of a small amount of a high boiling, aromatic alcohol to the emulsion prior to coating. Further improvements are noted with the addition of small amounts of a humectant and a plasticizer. The films resulting from this novel process can be handled without problems in the modern, automatic changing devices, for example.
