Abstract

1298335 Photographic emulsions AGFA GEVAERT N V 8 Dec 1969 [11 Dec 1968] 58844/68 Heading G2C A photographic silver halide emulsion contains at least one light-absorbing dye which (a) absorbs light in the region to which the emulsion is sensitive giving an optical density of 0À05-0À14 measured at the absorption maximum of the dye(s), and (b) is decolourized and/or removed during processing. Many types of dye may be used.
