-0- FLUOROSURFACTANTS CONTAINING POLYGLYCIDYL GROUPS Abstract of the Disclosure A water-soluble compound useful as a surfact- ant in photographic elements comprises a hydrophobic fluorocarbon group linked with a hydrophillc poly- glycidyl group containing an anion and cation. The compound preferably has the formula: [(YXET?)xT?]Mu wherein Y is a fluorocarbon group; X represents one or more linking groups; E is a polyglycidyl group; T1 and T2 are anionic groups; M is a cationic group and z is an integer of 1 to the maximum number of sites on E to which an anionic group is attachable; y is 0 or 1 provided that z + y is at least equal to 1; x is an integer of 1 or 2; and u is the number of cations required to neutralize the anionic groups present.
