Abstract

Use of a polymer as a levelling agent or anti-cratering agent, said polymer comprising at least one fluorinated unit represented by formula 1, (Formula 1) wherein R?1 is a moiety represented by Cn?F2n+1?-(CH2?)m?-, ΛCn?F2n?-(CH2?)m?-, Cn?F2n+1?-(CII2?)m?-(OCII2?CIIR?5)p?-, ΛCn?F2n?-(CH2?m?-(OCH2?CHR?5)p′? Cn?F2n+1?-(CII2?)m?-X-, ACn?F2n?-(CII2?)m?-X-ΛCn?F2n?-(CH2?)m?-(OCH2?CHR?5)p?-X or Cn?F2n+1?-(CII2?)m?-(OCII2?CIIR?5)p?-X-; wherein A=H, Cl, Br, I, a C1–12? alkyl or a OC1–12 ?alkyl, wherein 4≦n≦20,0≦m˜≦4 and 0≦p≦20, wherein X is a spacer moiety selected from the group consisting of esters, amides, sulphoamides, mercapto groups, poltyurethane groups and alkyl groups, wherein R?2, is H, a metal moiety, an (alkyl)ammonium moiety or an alkyl group, Cn?F2n+1?-(CII2?)m?-, ACn?F2n?-(CII2?)m?-, Cn?F2n+1?-(CII2?)m?-(OCII2?CIIR?5)p?-, ΛCn?F2n?-(CH2?)m?-(OCH2?CHR?5)p′? Cn?F2n+1?-(CH2?)m?-X-, ΛCn?F2n?-(CH2?)m?-X-, ACn?F2n?-(CH2?)m?-(OCH2?CHR?5)p?-X or Cn?F2n+1?-(CH2?)m?-(OCH2?CHR?5)p?-X-; wherein A=H, Cl, Br, I, C1–12? alkyl or OC1-12 alkyl, wherein 4≦n≦20, 0≦m≦4 and 0≦p≦20, wherein X is a spacer moiety selected from the group consisting of esters, amides, sulphoamides, mercapto groups, poly…
