Abstract

350,973. Photographic film packs. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Dec. 10, 1929, No. 37870. Convention date, Dec. 10, 1928. Void [Published under Sect. 91 of the Acts]. [Class 98 (i).] A photographic film pack has its case, or the cardboard sheet of the last tab, or both, wholly or in part in a colour which is distinguishable from a dark background in the dark room under red light or under green light. The colour, which is preferably such that its appearance under red light is different from that under green light, may be applied as a coloured celluloid lacquer or as adhesive labels and may be used to denote the nature of the film. For example a pack containing orthochromatic films may be in red and a pack containing panchromatic films in green.
