Abstract
396,585. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Oct. 28, 1932, No. 30290. Convention date, Nov. 25, 1931. [Class 98 (ii).] A tripack of the kind described in Specification 389,341, which comprises a front support carrying a blue-sensitive layer, an intermediate support carrying on its front surface a greensensitive layer coated with a yellow filter layer and on its rear surface a red filter layer, and a rear support carrying a panchromatic emulsion, is provided with an additional yellow filter layer on the blue-sensitive emulsion in order to flatten the gradation of the blue record image, and yield images of the same gradation on all three emulsion layers. The two yellow filters together absorb all blue rays.
