Photographic elements with j-aggregating carbocyanine infrared sensitizing dyes

摘要

The present invention provides a photographic element comprising an infrared light sensitive silver halide emulsion layer containing silver halide grains that exhibit low cubicity and are sensitized to a maximum absorption over 700 nm with a carbocyanine dye free of water soluble groups, wherein said layer additionally comprises a pyrimidino- or triazino-stilbene compound containing at least 6 sulfonic acid or sulfonate substituents.
