Latest Patents
Celada holds a patent titled "Ageing improvements of photographic elements comprising dextran." This invention relates to a process for enhancing the ageing properties of a silver halide photographic element. The process involves a support bearing at least one light-sensitive silver halide emulsion layer and at least one light-insensitive layer. The silver halide light-sensitive emulsion layer includes negative acting surface latent image-type silver halide grain in association with a contrast promoting agent and a hydrazine compound. By adding a total amount of at least 0.40 grams per square meter of dextran to the light-sensitive silver halide emulsion layer and/or to the light-insensitive layer, the ageing properties of the photographic element are significantly improved. Celada's innovative approach has the potential to enhance the longevity and quality of photographic images.
