Abstract
335,432. I. G. Farbenindustrie Akt.- Ges. Nov. 12, 1928, [Convention date]. Colour kinematography. - Component colourrecord pictures of smaller size than 19 by 25 mm., and intended for additive synthesis, are taken in recurring sequence upon a narrow film of less than 35 mm. width carrying a high-speed panchromatic emulsion of the reversal type, and the pictures are developed as positives by the silver reversal process. The emulsion referred to contains a mixture of coarse and fine grains of silver bromide, of which the highly-sensitive coarse grains are chiefly affected during the camera exposure, while the less-sensitive fine grains are affected during the second or reversal exposure. The known narrow films of 16 mm. width may be used.
