Abstract

852,067. Photographic emulsions. KODAK Ltd. Oct. 11, 1956 [Oct. 12, 1955], No. 30937/56. Drawings to Specification. Class 98(2) Photographic silver halide emulsions are supersensitized with a combination of a dicarbocyanine dye of the general formula wherein R and R are alkyl or substituted alkyl groups, X is an anion, n is 0 or 1, Z completes a benzthiazole, naphthothiazole, benzoxazole, naphthoxazole, benzoselenazole or naphthoselenazole nucleus and Z1 completes a naphthothiazole, benzoxazole, naphthoxazole, benzoselenazole, naphthoselenazole, 2-quinotine, 4-quinoline, benzimidazole or 5;6-benzoquinoline nucleus, and a bis (s-triazin-2-ylamino) stilbene compound of the general formula: wherein R4 and R5 are hydrogen atoms or water-solubilizing groups such as sulpho or carboxyl or their alkali metal, ammonium or amine salts, and D and D1 represent s-triazin-2-yl nuclei. The triazinyl nuclei may be substituted in the 4- and/or 6-positions by hydroxy, aryloxy or substituted aryloxy (e.g. phenoxy, p-toloxy, or p-sulphophenoxy), alkoxy (e.g. methoxy or ethoxy), heterocyclic (e.g. morphotinyl or piperidyl), alkylthio, arylthio, heterocyclothio (e.g. benzthiazylthio), amino, alkylamino (e.g. methylamino, ethylamino, propylamino, dimethylamino, diethylamino or dodecylamino), cyclohexylamino, #-hydroxyethylamino, di-#-hydroxyethylamino, #-sulphoethylamino, arylamino or substituted arylamino (e.g. anilino, sulphoanilino, chloroanilino, anisylamino, toluidino, carboxyanilino, hydroxyanilino, sulphonaphthylamino, aminoanilino or acetamido-anilino), or heterocyclylamino (e.g. 2-benzthiazylamino or 2-pyridylamino) groups, or by halogen atoms. A list of suitable s-triazine compounds is given including ones wherein the triazine nuclei have a 4-[4<1>-(N<1>-4<11>- sulphobenzyl-N<1>-ethyl)amino-anilino] or 4-[4<1>- (5<11>-keto-3<11>-methyl-2<11>-pyrazolin-1<11>-yl) - anilino] substituent. The triazinyl compounds are described in Specifications 595,065, 623,849, 624,051, 624,052, 678,291, 681,642 and 705,406 and in U.S.A. Specifications 2,171,427, 2,473,475, 2,595,030 and 2,660,578. Such compounds also are sold under the trade names of "Calcofluor White" and "Blancofor" and under the Registered Trade Marks "Leucophor", "Tinopal" and "Hiltamine". The supersensitizing combinations of the invention are effective in overcoming the desensitization caused by adding certain colour couplers or ultra-violet absorbers to photographic emulsions. Couplers specified for use in the invention are those in Specifications 541,589 and certain couplers in Specifications 545,448, 627,814, 649,660, 680,488, 736,922, 739,913 and 791,219. Specifications 513,170, 556,266, 581,772, 770,494, 851,186, 852,069, 852,074 and 852,075 also are referred to.
