Abstract

1,144,289. Tanning developing agents. E.I. DU PONT DE NEMOURS & CO. May 24, 1967 [June 3, 1966], No.24224/67. Heading G2C. Silver halide emulsion layers or layers of photographic silver halide materials in water permeable relationship therewith or developers therefore contain as a tanning developing agent a polyhydroxy-spiro-bis-indane in which one of the benzene rings contains at least two hydroxyl groups. The tanning developing agents may be used in conjunction with auxiliary developers e.g. hydroquinone and alkyl gallates. The emulsion is preferably coated on a matter support as described in Specification 1,121,859 and the binder for the emulsion may be gelatine and a vinylidene chloride/alkyl acrylate copolymer or other water permeable colloid.
