Abstract
523,478. Processing photographic material. DU PONT FILM MANUFACTURING CORPORATION. Jan. 2, 1939, No. 90. Convention date, Jan 3, 1938. [Class 98 (ii)] In the production or treatment of photographic material, there is incorporated in the light-sensitive layer or in a layer adjacent thereto or in a processing bath or there is applied to the surface of developed photographic material an organic pentavalent nitrogen compound which conforms to one of the general formulae where X is a hydroxyl group or negative acid radical such as chlorine, bromine or iodine, R 1 , R 2 , R 3 , and R, are hydrocarbon or substituted hydrocarbon radicals at least one of which contains six or more carbon atoms and two of which may be linked to form a ring, R is a hydrocarbon or substituted hydrocarbon radical containing six or more carbon atoms, Y is CO or SO 2 , and Z is hydrogen or a salt or esterforming atom or group such as an alkali metal. In formulae II and IV the nitrogen atom forms part of a heterocyclic ring. Examples of suitable hydrocarbon radicals and of compounds according to the invention are given. The compounds may be applied to an emulsion surface by bathing the material in an aqueous-alcoholic solution thereof, or the solution may be applied to the surface by a roller or by spraying, or the film may be passed between rollers. The compounds may be applied in conjunction with developing, fixing, bleaching, and stop baths, particularly in the case of colour films. The photographic materials produced or treated may have gelatino silver halide emulsion, bichromated colloid layers containing protein binding agents, gelatin layers containing diazonium salts for use in the diazotype-process, and emulsion layers for the production of coloured images suitably sensitized and containing salts of leuco bases and esters of leuco bases of dyes. In an example the compound prepared from α-bromostearic acid and trimethylamine is added to a gelatino silver halide emulsion before coating on to a cellulose nitrate support. The resultant film may be developed in a metolhydroauinone borax developer. The sensitizing properties of dyes such as thiocarbocyanine iodides are not effected. Sensitizing dyes which are either free bases or salts may be employed. In another example the compound prepared from sodium chloracetate and dimethyloctadecylamine is added to a gelatino silver halide emulsion before coating on a cellulose acetate support. The reaction product of chloracetic acid and dimethyl-n-dodecylamine may be added to a metol-hydroquinone borax developer. The reaction product of cetyl bromide and γ-dimethylamino-#-hydroxy propanesulphonate may be mixed with 10 per cent. gelatin solution and coated over a panchromatic emulsion layer. Other compounds added to gelatino silver halide emulsions are N - (n-decyl) - α - betaine, the reaction product of sodium chloracetate and dimethylolcylamine, and the compound obtained by neutralizing the reaction product of chloracetic acid and dimethyltetradecylamine. A lubricating composition applied to a film after processing comprises C - (n - hexadecyl) - α - betaine, glycerine or ethylene glycol, ethyl alcohol, and water.
