Abstract
972,991. Photographic materials and processes. KODAK Ltd. Dec. 23, 1960 [Dec. 28, 1959], No. 44324/60. Heading G2C. Photographic light-sensitive material for use in the transfer process as described in Specification 725,667 comprises a substantially unhardened silver halide emulsion layer containing a tanning developing agent, a non-tanning, self-coupling, developing agent, and a tri-alkyl or tri-phenylphosphite, the phenyl groups of which may carry substituents. The tanning developing agent is preferably 3, 4-dihydroxy-diphenyl, 2, 5-dihydroxydiphenyl, 2, 3-dihydroxy-diphenyl or 5, 6, 7, 8- tetrahydronaphthohydroquinone, but it may also be hydroquinone or pyrocatechol. The non-tanning, self-coupling, developing agent may be 4-methoxy- 1-naphthol or 8-hydroxy-alpha-naphthol. Phosphites specified for use in the invention are tri-sio-octyl phosphite, tricresyl phosphite, triphenyl phosphite, tri-(2-methoxy-phenyl) phosphite, 2-ethylhexyl-, octyl-phenyl phosphite and the trimethyl-, tri-npropyl-, tri-iso-propyl-, tri-n-butyl-, tri-n-hexyl-, and tri-2-ethylhexyl phosphites. The exposed material is developed in an alkaline solution such as aqueous sodium carbonate, as described in Specification 725,667, and pressed against a receiving sheet to transfer a thin layer of unhardened gelatin in the shadow areas. The developing solution may contain #-diethylamino-ethanol as described in Specification 945,496 or potassium carbonate/acetamide as described in Specification 933,004. Specifications 655,274 and 800,772 also are referred to.
