Abstract
475,191. Colour photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) May 20, 1936, No. 14292. [Class 98 (ii)] Colour photographic material comprises particles of different silver halide emulsions each sensitive to a different region of the spectrum and containing a dyestuff component for colour development as defined in Specifications 458,400 and 465,823. In an example, one silver halide emulsion contains di - (benzoylacetic acid) - benzidide, a green sensitized silver halide emulsion contains 1 - (p - stearylaminophenyl) - 3 - methyl - 5- pyrazolone and filter yellow and a red-sensitized silver halide emulsion contains di-(1-oxy- 2-naphthoyl)-benzidide and filter yellow. The three emulsions are formed into small particles and mixed, and the mixture is applied with a binder to the support. After exposure, the film is developed in an ordinary developer, strongly illuminated, and re-developed in a p-diethylaminoaniline developer. The silver is removed before or after colour development. The film may be developed to a negative, which is printed on to similar material to give a positive. Specifications 15055/12 and 2562 /13, [both in Class 98 (ii)], also are referred to.
