Stabilization of emulsions sensitized with alkylene oxide polymers

Claim 1

A LIGHT-SENSITIVE SILVER HALIDE EMULSION SENSITIZED WITH AN ALKYLENE OXIDE POLYMER SELECTED FROM THE CLASS CONSISTING OF (1) POLYALKYLENE GLYCOLS, (2) CONDENSATION PRODUCT OF ALKYLENE OXIDE WITH GLYCOLS, (3) CONDENSATION PRODUCTS OF ALKYLENE OXIDE WITH ALIPHATIC COMPOUNDS SELECTED FROM THE CLASS CONSISTING OF ALCOHOLS, ACIDS AND AMINES AND (4) CONDENSATION PRODUCTS OF ALKYLEND OXIDE WITH HEXITOL RING DEHYDRARTION PRODUCTS, SAID ALKYLENE OXIDE CONTAINING FROM 2 TO 4 CARBON ATOMS AND SAID ALKYLENE OXIDE POLYMER HAVING A MOLECULAR WEIGHT OF AT LEAST 300, SAID EMULSION CONTAINING A SMALL AMOUNT OF A MERCURY COMPOUND SELECTED FROM THE CLASS CONSISTING OF (1) A MOLECULAR ADDITION COMPOUND O A MERCURY SALT WITH A NITROGEN COMPOUND OF THE CLASS CONSISTING OF HETEROCYLIC NITROGEN COMPOUNDS IN WHICH AT LEAST THREE BONDS OF THE HETEROCYCLIC NITROGEN ATOM ARE ATTACHED TO CARBON, AMINE-SUBSTITUTED MONONUCLEAR AROMATIC COMPOUNDS IN WHICH THREE BONDS OF THE AMINO NITROGEN ATOM ARE ATTACHED TO CARBON, THEIR HALOGEN ACID SALTS, AND THE HALOGEN ACID SALTS, OF ALIPHATIC AMINES CONTAINING AT LEAST THREE CARBON ATOMS, (2) ORGANIC COMPOUNDS OF MERCURY IN WHICH THE MERCURY ATOM IS ATTACHED BY A NON-IONIC MERCURY TO CARBON BOND TO A CYCLIC ORGANIC NUCLEUS AND BY AN IONIC BOND TO AN ANION, AND (3) SIMPLE SALTS OF MERCURY WITH ORGANIC AND INORGANIC ACIDS.
