摘要:
A surface-active fluorinated composition characterized by the association therein of from 35% to about 60% of at least one surface-active ampholyte compound of the formula ##EQU1## wherein n is an integer between 1 and 20, a is a number between 2 and 10, R.sub.1 is an atom of hydrogen or an alkyl radical containing from 1 to 6 atoms of carbon, R.sub.2 and R.sub.3 are alkyl radicals containing from 1 to 3 atoms of carbon, at least one of which is the methyl radical and p and q are integers between 0 and 10; from about 20% to about 40% of at least one surface-active fluorinated non-ionic compound of the formulaC.sub.n F.sub.2n.sub.+1 -- (CH.sub.2).sub.a -- CO--O--(CH.sub.2 --CH.sub.2 --O).sub.m R.sub.4wherein n and a have the same meaning as above, m is an integer between 1 and 20 and R.sub.4 is an alkyl radical containing from 1 to 6 atoms of carbon; and from about 8% to about 40% of at least one amine salt compound of the formula ##EQU2## wherein X is the group CO or SO.sub.2 R.sub.1, R.sub.5 and R.sub.6 may be hydrogen atoms, alkyl radicals containing from 1 to 6 atoms of carbon, or the group ##EQU3## in which R.sub.2, R.sub.3, p and q have the values given above.
