Fluoroaliphatic-thio,-sulfinyl and -sulfonyl substituted bicycloaliphatic amic acid amine salts of the formula: <IMAGE> (I) where Rf is perfluoroalkyl, R' is alkylene optionally interrupted by -O-, -S- or <IMAGE> where Ra is hydrogen or alkyl, Y is lower alkylene or -O-, n is 0-2, R1 and R2 are independently hydrogen, lower alkyl, hydroxy lower alkyl or together with the nitrogen to which they are attached, represented morpholino, R3, R4 and R5 are independently hydrogen, lower alkyl, or hydroxy lower alkyl, R6 is lower alkyl, carboxy lower alkyl, sulfo lower alkyl, hydroxy lower alkyl, benzyl or together with R5 and the nitrogen to which they are attached represent morpholino, and R is hydrogen or methyl are provided. These salts applied in the form of aqueous solutions, dispersions or emulsions are useful in rendering cellulosic and natural and synthetic polyamide materials oil and water repellent. |
