PUBLISHED APRIL 7, 1970 T873,003 PHOTOGRAPHIC GELATIN HARDENING 'COM- POSITION CONTAINING MAGNESIUM SULFATE Lawrence J. Donivan, 1669 Lake Ave., Rochester, NY. 14650 Continuation-impart of application Ser. No. 595,353,
Nov. 18, 1966. This application Sept. 15, 1969, Ser.
Int. Cl. G03c 1/30 US. Cl. 96-111 No Drawing. 12 Pages Specification The hardening and swelling of photographic gelatin layers is controlled by treatment with acidic aqueous hardening solutions containing magnesium sulfate and an aldehydic gelatin hardening agent such as a mixture of formaldehyde and succinaldehyde bis-bisulfite. The solutions allow the gelatin layers to be carried through the various processing zones of roller transport processing systems without the production of roller pattern on the layers. Crystallization of salts on the apparatus is also avoided. Representative packaged compositions which are dissolved in Water to form a working hardening solution comprise 1) a dry mixture of chemicals containing an aldehyde bisulfite, and magnesium sulfate and (2) an aqueous solution of a mixture of acetic acid and formaldehyde.
