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.
Abstract:
The present invention is directed to a method of scanning silver-halide-containing color photographic and photothermographic film. In particular, the present invention comprises record shifting by means by employing at least one infrared dye in a color unit of the film, thereby forming at least one image record in the infrared. This expedient leads to the formation of high quality images, especially when scanning photothermographic elements in which the silver halide, metallic silver, and/or any organic silver salts have not been removed.
