Abstract
Abstract Fluorine-containing surfactants according to formula (Rf--X) n --A--L--Z wherein Rf is a short-chain fluorine-containing group derived from hexafluoropropylene or trifluorochloroethylene, X is --O--, --S--, or --SO 2 --, n is at least 2, the Rf groups being same or different, L is a monovalent bond or a bivalent bridging group such as --COO--alkylene, --CONR 1 --alkylene, or --SO 2 NR 1 --alkylene, wherein R 1 is hydrogen or C 1 -C 5 alkyl, and Z represents a hydrophilic polyoxyethylene group or a hydrophilic group such as ##STR1## wherein M is hydrogen, an alkali metal, ammonium, or organic ammonium, and R 3 is alkyl; A is an aliphatic, aromatic, or aliphatic-aromatic group. These surfactants can be used in hydrophilic colloid layers, which may form part of light-sensitive silver halide materials.
