FLUORINE-CONTAINING SURFACTANTS AND THEIR USE IN HYDROPHILIC COLLOID COATING COMPOSITIONS AND LIGHT-SENSITIVE SILVER HALIDE MATERIALS

Novel fluorine-containing surfactants and their use i hydrophilic colloid coating compositions and lightsensitive silver halide materials. Fluorine-containing surfactants according to formula(Rf-X)n-A-L-Z wherein Rf is a short-chain fluorine-con-taining group derived from hexafluoropropylene or trif...

Zusammenfassung:	Novel fluorine-containing surfactants and their use i hydrophilic colloid coating compositions and lightsensitive silver halide materials. Fluorine-containing surfactants according to formula(Rf-X)n-A-L-Z wherein Rf is a short-chain fluorine-con-taining group derived from hexafluoropropylene or trifluorochloroethylene, X is -O-, -S-, or -SO2-, 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, -CONR1-alkylene, or -SO2NR1-alkylene, wherein R is hydrogen or C1-C5 alkyl, and Z represents a hydrophilic polyoxyethylene group or a hydrophilic group such as -SO3M, -OSO3M, -COOM, and wherein M is hydrogen, an alkali metal, ammonium, or organic ammonium, and R3 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. GV.1049
