Fluorine compounds
The present invention relates to fluorine compounds (I), (II) and (III), to processes for the preparation thereof, and to the use thereof.
1. A compound of the formulae (XI) to (XVI)
where
Rs is an optionally fluorinated alkyl group,
n is a number of from 5 to 20,
PEG is a polyethylene oxide group and
Rf is a group of the formula CF 3 —(CF 2 ) a —O b —(CF 2 ) c —O d —,
where
a=1, 2 or 3,
b=0 or 1,
c=0, 1, 2 or 3 and
d=0 or 1.
2. The compound of claim 1 , wherein Rf is a group of the formula CF 3 —(CF 2 ) 1-3 — or CF 3 —(CF 2 ) 1-3 —O—.
3. An additive in a composition, wherein the composition is selected from the group consisting of: paints, coatings, printing inks, protective coatings, special coatings in electronic or optical applications, photoresists, top antireflective coatings or bottom antireflective coatings, developer solutions and wash solutions and photoresists for photolithographic processes, cosmetic products, agrochemicals, floor polishes, photographic coatings and coatings of optical elements; and the additive comprises a compound of claim 1 .
4. A composition comprising one or more compounds according to claim 1 and a vehicle which is suitable for the respective application and optionally further specific active substances.
5. The composition according to claim 4 , characterised in that the composition is selected from the group consisting of: paint and coating preparations, fire-extinguishing compositions, lubricants, washing and cleaning compositions, de-icers, developer solutions and wash solutions and photoresists for photolithographic processes, cosmetic products, agrochemicals, floor polishes and hydrophobicising compositions for textile finishing or glass treatment.
6. A coated article whose coating has been produced using at least one compound according to claim 1 .
