Zusammenfassung:	A method for imparting water- and oil-repellent properties to leather is disclosed which uses as the treating composition a solution of A. A CONDENSATION PRODUCT FORMED BY (1) AN ALUMINUM ALCOHOLATE OF A LOWER MONOHYDROXY ALCOHOL HAVING A CARBON CHAIN LENGTH OF ONE TO FOUR CARBON ATOMS WITH (2) A PHOSPHORIC ACID MONOESTER OF A HIGHER FATTY ALCOHOL HAVING A CARBON CHAIN LENGTH OF 12 TO 20 CARBON ATOMS, AND B. A FLUORINATED COMPOUND COMPRISING LIPOPHILIC RADICALS HAVING A CARBON CHAIN LENGTH OF EIGHT TO 20 CARBON ATOMS, SELECTED FROM THE GROUP CONSISTING OF FLUOROCARBOXYLIC ACIDS AND ESTERS THEREOF, AND FLUOROALCOHOLS AND ESTERS, ETHERS AND ACETALS THEREOF IN AN INERT ORGANIC SOLVENT; THE SOLUTION IS APPLIED TO DRY LEATHER BY IMMERSION OR SPRAYING, AS WELL AS THE WATER- AND OIL-REPELLENT LEATHER SO PRODUCED.
