Abstract
384,312. Colour photography. LEJEUNE, F., 19, Auerspergstrasse, Vienna. April 30, 1931, No. 12805. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 4, 1931.] [Class 98 (ii).] Relates to the production of photographs in natural colours by forming component relief images, treating such images with appropriate salt solutions, and bringing them successively into contact with a colloid layer and, after each imbibition, treating with a precipitant to produce an insoluble coloured precipitate; and consists in forming the yellow, blue, and red component images respectively of lead chromate, Turnbull's or Prussian blue, and nickel dimethylglyoxime. To produce sharp images and avoid spreading, the precipitants may be incorporated in the colloid layer in waterinsoluble form, e.g. the colloid layer contains a white precipitate of lead carbonate or hydrocarbonate, dimethylglyoxime is incorporated in the colloid layer during coating, and the coating is treated with a solution of ferric chloride.
