Abstract
734,932. Colour photography. PAPADAKIS, S. April 16, 1952 [April 25, 1951], No. 9516/52. Class 98(2). A three-colour picture is made on a support carrying a single layer as of gelatin or collodion by immersion thereof in a bath of a sulphuric ester salt of a leuco derivative of a blue colour base, exposure through a separation negative, and washing to eliminate residual salts; with repetition of these operations using leuco derivative salts for the red and yellow component colours. The baths may comprise the salts of 5-7 5<SP>1</SP>-7<SP>1</SP>-tetrabromoindigo or 6-6<SP>1</SP>- dibromindigo for the blue, of 1-2 anthraquinone-naphthacridone for the red, and of flavanthrene for the yellow, and may include glycerin and thiosinamine in acid solution.
