Description

“In October, Eggert of the Agfa Research Department, read a paper at the Berlin meeting of the Deutsche Gesellschaft für photographische Forschung, on the Pantochrom subtractive lenticular bipack tricolor process. (Fig. 1) The green and blue separation positive images are formed in a lenticular emulsion (nearest the lens) and the red separation image is formed in a single layer coating in contact with the emulsion side of the lenticularfilm. Positives are printed on double coated stock carrying on one side an ordinary silver bromide emulsion, and on the other a double coated emulsion having a purple pigment in the upper layer and a yellow pigment in the lower layer. Printing is effected by contact simultaneously from both camera films, the front one, which has gone through a reversal process, being printed on the double emulsioned side of the positive and the other camera film on the single emulsion side. The single emulsion of the projection print (carrying the sound-track) is processed by a catalytic bleach method to form a blue-green image, whereas the double emulsion side is processed similarly to yield the remaining two-color subtractive positive.”
