Title: Improvements in and relating to the preparation of pigments
IPC: C09C3/08
Filed: 1949-04-21
Abstract: Pigments of improved texture are prepared by incorporating in an aqueous paste or suspension of the pigment before drying a water-soluble salt of a branched chain carboxylic acid of general formula C17H217r, COOH, where n=3 to 39.  It is preferred that the acid has at least six carbon atoms in the molecule and good results have been obtained using an acid having two chains of at least two carbon atoms attached to the carbon atom in the L-position to the carboxytic acid group.  Specified acids are isobutyric, 2-ethyl butyric, 2-ethyl pentric, 2-ethyl hexoic, 2-ethyl heptoic and isononoic acids.  The salt is preferably an ammonium one but sodium, potassium or an alkylolamine salt may be used.  The quantity of salt preferred is from 5-6 per cent by weight of the pigment, but up to 10 per cent or more may be used.  Specified pigments are the blue pigments, particularly iron blue, lead chromate, chrome green, phthatozyamine blue or organic pigments such as Helio red or Lithol red.  The products may be incorporated into paints, enamels, lacquers &c.

Title: Improvements in or relating to the treatment of photographic images
IPC: G03C5/38
Filed: 1938-04-06
Abstract: 513,288. Photographic processes. DU PONT FILM MANUFACTURING CORPORATION. April 6, 1938, No. 10571. Convention date, April 7, 1937. [Class 98 (ii)] The solvent action of aqueous sodium, thiosulphate solution on silver salts present in a gelatine emulsion layer (which may be composed of several sub-layers) is restricted to the silver salts adjacent to the surface of the layer by using a solution containing at least 70, e.g., between 70 and 90, parts of weight of crystalline sodium thiosulphate to 100 parts by weight of added water, such a solution having a low rate of effective penetration through the layer due to its high viscosity. The invention can be used for fixing only the outer of two developed silver images or only the outer image or images of more than two images superposed in a gelatine layer carried on a single support or to the elimination of the outer of two superposed developed silver images or the outer image or images of more than two superposed developed silver images and including the initial step of reconverting the silver images to silver salts by bleaching before treatment with the thiosulphate solution. The latter application can be used in the production of separate colour-component records from inseparable records formed by simultaneous exposure on a bipack or monopack and includes the steps of first making a single intermediate copy of the superposed records, reconverting all the original superposed images to silver salts, then eliminating the outer image by treatment with sodium thiosulphate solution as aforesaid and subsequently redeveloping the remaining original image or images and forming an independent copy of the eliminated record by printing from the combination of the intermediate record and the remaining original record or records in register, and when there are more than two original records, repeating the steps aforesaid until all but one of the records have been eliminated. The constitution of bleaching and developing baths is given. In the above examples the surface portion of the gelatine layer containing the silver salts to be acted upon by the sodium thiosulphate solution is initially substantially dry and the underlying portion of the layer is allowed to remain wet from previous processing steps. The invention can be applied to composite or trick cinematography for the preparation of travelling mattes wherein an object is photographed under one quality of illumination against a background of another quality illumination, exposures being made simultaneously on a two-layered film and the outer of the images recorded by the two-layered film being removed by the use of a sodium thiosulphate solution as aforesaid.
