Document Type and Number:
WIPO Patent Application WO2001057593
Kind Code:
A9
Abstract:
The invention relates to color photographic materials used for color image recording in the visible and infrared regions. The inventive material consists of a polymer base on one side of which an ant-halo backing is coated and at least two light-sensitive layers are coated on the other side. A light-sensitive layer is made from silver bromide-iodide emulsion containing microcrystals with octahedral or flattened faces or mixture thereof and with grains ranging from 0.5 to 1.5 mu m. One light-sensitive layer (in case of two or more layers) comprises an infrachromatic sensitizing polymethine dye corresponding to formula (I) cited in the description. The other light-sensitive layer comprises more than one orthochromatic polymethine dye of formula (II) cited in the description. The third light-sensitive layer, if any, comprises polymethine dye of formula (III) cited in the description. Auxiliary gelatin layer containing a hardener are applied between the light-sensitive layers. As a hardener preferably triazine-1,3,5 is used. This material possesses a high photographic sensitivity and resolving power.
