Abstract

333,668. Herzog, H., and Herzog, C., (trading as Herzog & Co., J.). June 4, 1929. Colour photography.-For the production of colour photographs consisting of superposed components produced on ready-coloured material by a tanning development method, the component negatives are printed on transparent supports coated with gelatin emulsions dyed with non- diffusing colloidal and highly transparent dyes, e.g. substantive dyes such as the monazo, diazo or tetrazo dyes. The following dyes are mentioned, Erica, alkali blue, benzo purpurin, dianil red, dianil ruby, Congo red, Hessian purple, thiazo yellow and Para yellow. The developed prints are transferred to and superposed upon a common final support. In developing the prints, a considerable percentage (60 to 100 per cent) of sulphite is added to the developer (e.g. pyrocatechin). The strength of the colours may be modified by organic reducers such as alcohol, acetone, acetic acid, benzol, or ammonia.
